Top Things You Didn’t Know You Could Do With Netlify CLI

(This is a sponsored post.)

First things first, if you didn’t know Netlify had a CLI, they do.  One of my favorite things about it running the command netlify dev on nearly any static-site generator project is seeing it detect what it should be doing and spinning the site up in a dev server for you. But not just any dev server, a dev server that replicates the Netlify environment, meaning things like running your serverless functions and making your environment variables available.

Here are five more things you can do with it that you might not realize.

1) Create a new site from a template

That’s right, spin up a new site by typing a single command and walking through the steps. Try it:

netlify sites:create-template

There is a shorthand to the CLI as well! Try the above as ntl sites:create-template

As Charlie Gerard writes in a blog post about this:

At the moment, our templates include a Gatsby and Hugo starter with the Netlify CMS, as well as a Next.js starter. 

2) Manage your environment variables 

The netlify env command, now in Beta, allows you to control environment variables. You can list them out with netlify env:list, get and set (and unset) them. My favorite: move a whole set of them from one site to another like netlify env:migrate --to <to-site-id>.

3) Test serverless functions

By virtue of spinning up your site locally with the Netlify CLI, your serverless functions will run. You can test that they are working and inspect the network traffic and such that way. But the CLI can help you as well, the netlify functions command is capable of testing functions at the command line level. For example, netlify functions:invoke can trigger a function with simulated data.

4) Live stream your Dev environment

Here’s Melanie Crissey on the Netlify Blog about this:

While Netlify’s collaborative Deploy Previews are our go-to for asynchronous feedback, sometimes you need to drop everything and pair on an issue together. That’s when Netlify Live really shines.

For example, just last week, our team was working quickly to debug some funky edge case issues with authentication for the Your Year on Netlify project. Zach Leatherman, who was working on the fix, spun up a local version of the app with Netlify Live. Within minutes, he was able to see the logs, identify the issue, and make a few changes. Meanwhile, I was able to test out the fix before it was ever deployed—without pulling down a copy of his latest version from a repo. Netlify CLI to the rescue and problem solved!

Remember how I mentioned you spin up a dev environment locally with netlify dev? The trick here is to do netlify dev --live. So rather than a localhost URL that only you would be able to see, you’ll get a special netlify.live URL that the world can see.

5) Run netlify switch to switch between different Netlify accounts, like from your personal side project to a work project

You literally auth with the CLI (netlify login, imagine that), so that you can act on behalf of your own Netlify account. Deploy sites and whatnot. But it’s perfectly reasonable that you have multiple Netlify accounts (like work and personal). Running netlify switch makes it trivial to move between accounts.


This video is 50 seconds long and shows how you can go from having some static files locally to a deployed with the CLI:

Netlify Has Scheduled Functions

(This is a sponsored post.)

Hey! Scheduled Functions are cool! Think of them like a CRON job. I want this code to run every Monday at 2pm. I want this code run every hour on the hour. That kind of thing. Why would you want to do that? There are tons of reasons! Perhaps something like “send my newsletter” where you write it on your site in Markdown, it gets processed into an email template and sent out via a Netlify Function. Now you could make that happen on a set schedule. Or something like “send all my new blog posts out, if there are any.”

This is pretty near and dear to me, because I’ve reached for paid outside services to do this for me in the past!

See, I have a little mini site right here on CSS-Tricks that is very time-based in that it lists upcoming conferences. It’s a totally static site, so once a date is passed, it, uh, kinda doesn’t matter, the site just stays how it is. But there is code that during the build process, it only builds out conferences in the future, not the past. So the trick is to run the build process every day.

Before Scheduled Functions, I used Zapier to do this, which has been humming along doing this just fine for years:

But the knowlege of how that works is basically locked up in my head. Plus, I’m doing it on a non-free third-party service, and there is always a little bit of Rube Goldberg-y technical debt to that.

I’m literally switching up how I’m doing it right this second as I type out this blog post. I’m just going to write the dumbest function ever that kicks a POST request to the URL that Netlify gives me to trigger builds and do it once a day. That’s it.

Might as well keep that URL as an “Enviornment Variable” like process.env.BUILD_SECRET or whatever

With this in place, I’m gonna switch off my Zap and just rest easy knowing all this functionality is now shored up in one place.

This is a Beta feature, for the record. Netlify doesn’t recommend it for production just quiiiiite yet, as per the Labs documentation. But my thing isn’t super mission-critical so I’m giving it a shot.

What else might you use them for? The blog post about the new feature has some ideas:

• Invoke a set of APIs to collate data for a report at the end of every week

• Back up data from one data store to another at the end of every night

• Build and deploy all your static content every hour instead of for every authored or merged pull request, or

• Anything else you can imagine you might want to invoke on a regular basis!

Netlify Identity, a Key Aspect to Jamstack Development

(This is a sponsored post.)

Netlify is amazing at static file hosting, but it’s really so much more than that. You can build any sort of website, even highly dynamic apps, with the Jamstack approach and static file hosting at the core.

Say you want to build a TODO app with users. Those users will need to sign up and log in. Can’t do that with a static site, right? You can, actually. Netlify helps with Netlify Identity, a robust offering they’ve had for years. Enabling it is just a few clicks in the admin UI, and they even provide auth widgets so you have to build precious little to get this working.

Showing a login widget powered by Netlify Identity.

Now you’ve got a website with authentication, great! But how do you keep going with your TODO app? You’ll need some kind of cloud storage for the data on your user’s lists. For that, you’ll have to reach outside of Netlify to find a cloud storage provider you like. Netlify has had a first-class integration with Fauna for years, so that’s a good choice.

You’ll need to communicate with Fauna, of course, and being a static site, JavaScript is how that’s going to work. Fortunately, your client-side JavaScript can communicate with your own server-side JavaScript that Netlify helps with, which is called Netlify Functions. That’s right, Netlify helps you build/deploy Lambda functions. This means you can actually have the Lambda functions do the communicating with Faunda, keeping your API keys safe.

Those are the building blocks. This is a well-worn approach, and really at the heart of Jamstack. Need a head start? Netlify has templates for this kind of thing. Here are some examples with this approach in mind: netlify-fauna-todo-app and netlify-faunadb-example. We even have a tutorial that covers that. And there’s a one-minute video demo:

There you have it, a website that is every bit as dynamic as something you’d build with a traditional server. Only now, you’re building with Netlify meaning you get so many other advantages, like the fact that you’re deploying from commits to a Git repository and getting build previews, and every other amazing feature Netlify offers.

How to Create a Contact Form With Next.js and Netlify

We’re going to create a contact form with Next.js and Netlify that displays a confirmation screen and features enhanced spam detection.

Next.js is a powerful React framework for developing performant React applications that scale. By integrating a Next.js site with Netlify’s technology, we can quickly get a working contact form up and running without having to write any server-side code.

Not only is it a relatively fast process to set up forms to be processed by Netlify, but it’s also free to get started (with up to 100 free submissions/per site hosted on Netlify). Form submissions automatically go through Netlify’s built-in spam filter which uses Akismet and there are also options that can be configured to increase the level of spam detection.

Creating the contact form

Within the Next.js application we should create a ContactForm component to render the contact form inside of the contact page. If you’d like for this form to render at /contact, then the ContactForm component below with labels and input fields should be used within the pages/contact.js file.

const ContactForm = (   <form     name="contact-form"     method="POST"     action="contact/?success=true"   >     <label htmlFor="name">Name *</label>     <input       id="name"       name="name"       required       type="text"     />     <label htmlFor="company">Company *</label>     <input id="company" name="company" required type="text" />     <label htmlFor="email">E-mail Address *</label>     <input id="email" type="email" name="email" required />     <label htmlFor="message">Message *</label>     <textarea id="message" name="message" required></textarea>     <button type="submit">Submit</button>   </form> );

The above markup is required to render a form with a field for Name, Company, Email address and message with a submit button. When submitting the form, based on the value of the form’s action, it should redirect to contact/?success=true from /contact. Right now there is not yet a difference between the page’s appearance with and without the success query parameter, but we will update that later.

Our Contact.js file looks like this so far:

import React from "react"; const ContactPage = () => {  const ContactForm = (/* code in above code sample*/)    return (    <div>      <h1>Contact Us</h1>      {ContactForm}    </div>  ); };   export default ContactPage;

Now that we have the basic form set up, the real magic will happen after we add additional information for Netlify to auto-recognize the form during future site deployments. To accomplish this we should update the form to have the attribute data-netlify="true" and a hidden input field that contains the name of our contact form. In Netlify, once we navigate to our site in the dashboard and then click on the “forms” tab  we will be able to view our form responses based on the name that we’ve put in our hidden field. It’s important that if you have multiple forms within a site that they have unique names so that they are recorded properly in Netlify.

<form   method="POST"   name="contact-form"   action="contact/?success=true"   data-netlify="true" > <input type="hidden" name="form-name" value="contact-form" />

After successfully deploying the site to Netlify with the data-netlify attribute and the form-name field  then we can go to the deployed version of the site and fill out the form. Upon submitting the form and navigating to https://app.netlify.com/sites/site-name/forms (where site-name is the name of your site) then our most recent form submission should appear if we have successfully set up the form. 

Redirect to confirmation screen 

In order to improve the user experience, we should add some logic to redirect to a confirmation screen on form submission when the URL changes to /contact/?success=true. There is also the option to redirect to an entirely different page as the action when the form is submitted but using query params we can achieve something similar with the Next Router. We can accomplish this by creating a new variable to determine if the confirmation screen or the form should be visible based on the query parameter. The next/router which is imported with import { useRouter } from "next/router"; can be used to retrieve the current query params. 

const router = useRouter();   const confirmationScreenVisible = router.query?.success && router.query.success === "true";

In our case, the confirmation screen and form can never be visible at the same time; therefore, the following statement can be used to determine if the form is visible or not.

const formVisible = !confirmationScreenVisible; 

To give users the option to resubmit the form, we can add a button to the confirmation screen to reset the form by clearing the query params. Using router.replace (instead of router.push) not only updates the page but replaces the current page in the history to the version without query params. 

<button onClick={() => router.replace("/contact", undefined, { shallow: true })}> Submit Another Response </button>

We can then conditionally render the form based on whether or not the form is visible with:

{formVisible ? ContactForm : ConfirmationMessage}

Putting it all together, we can use the following code to conditionally render the form based on the query params (which are updated when the form is submitted):

import React, { useState } from "react"; import { useRouter } from "next/router";   const ContactPage = () => {  const [submitterName, setSubmitterName] = useState("");  const router = useRouter();  const confirmationScreenVisible =    router.query?.success && router.query.success === "true";  const formVisible = !confirmationScreenVisible;    const ConfirmationMessage = (    <React.Fragment>      <p>        Thank you for submitting this form. Someone should get back to you within 24-48 hours.      </p>        <button onClick={() => router.replace("/contact", undefined, { shallow: true })}> Submit Another Response </button>    </React.Fragment>  );    const ContactForm = (/* code in first code example */);    return (    <div>      <h1>Contact Us</h1> {formVisible ? ContactForm : ConfirmationMessage}    </div>  ); };   export default ContactPage;

Adding a hidden bot field

Now that the core functionality of our form is working, we can add additional spam detection to our form in addition to the base spam detection because Akismet is included with all Netlify Forms by default. We can enable this by adding data-netlify-honeypot="bot-field" to our form.

<form   className="container"   method="POST"   name="contact-form"   action="contact/?success=true"   data-netlify="true"   data-netlify-honeypot="bot-field" >

We also need to create a new hidden paragraph that contains a label named bot-field that contains the input. This field is “visible” to bots, but not humans. When this honeypot form field is filled, Netlify detects a bot and then the submission is flagged as spam.

<p hidden>   <label>     Don’t fill this out: <input name="bot-field" />   </label> </p>

Further customizations

  • We could explore another spam prevention option that Netlify supports by adding reCAPTCHA 2 to a Netlify form.
  • We could update the form to allow uploaded files with input <input type="file">.
  • We could set up notifications for form submissions. That happens over at https://app.netlify.com/sites/[your-site-name]/settings/forms where we can include a custom subject field (which can be hidden) for email notifications.

Full code

The code for the full site code is available over at GitHub.


The following code includes everything we covered as well as the logic for setting a custom subject line with what was submitted in the name field.

import React, { useState } from "react"; import { useRouter } from "next/router";   const ContactPage = () => {  const [submitterName, setSubmitterName] = useState("");  const router = useRouter();  const confirmationScreenVisible =    router.query?.success && router.query.success === "true";  const formVisible = !confirmationScreenVisible;    const ConfirmationMessage = (    <React.Fragment>      <p>        Thank you for submitting this form. Someone should get back to you        within 24-48 hours.      </p>        <button onClick={() => router.replace("/contact", undefined, { shallow: true })}> Submit Another Response </button>    </React.Fragment>  );    const ContactForm = (    <form      className="container"      method="POST"      name="contact-form"      action="contact/?success=true"      data-netlify="true"      data-netlify-honeypot="bot-field"    >      <input        type="hidden"        name="subject"        value={`You've got mail from $ {submitterName}`}      />      <input type="hidden" name="form-name" value="contact-form" />      <p hidden>        <label>          Don’t fill this out: <input name="bot-field" />        </label>      </p>        <label htmlFor="name">Name *</label>      <input        id="name"        name="name"        required        onChange={(e) => setSubmitterName(e.target.value)}        type="text"      />      <label htmlFor="company">Company *</label>      <input id="company" name="company" required type="text" />      <label htmlFor="email">E-mail Address *</label>      <input id="email" type="email" name="email" required />      <label htmlFor="message">Message *</label>      <textarea id="message" name="message" required/>      <button type="submit">Submit</button>    </form>  );    return (    <div>      <h1>Contact Us</h1> {formVisible ? ContactForm : ConfirmationMessage}    </div>  ); };   export default ContactPage;

Building a Tennis Trivia App With Next.js and Netlify

Today we will be learning how to build a tennis trivia app using Next.js and Netlify. This technology stack has become my go-to on many projects. It allows for rapid development and easy deployment.

Without further ado let’s jump in!

What we’re using

  • Next.js
  • Netlify
  • TypeScript
  • Tailwind CSS

Why Next.js and Netlify

You may think that this is a simple app that might not require a React framework. The truth is that Next.js gives me a ton of features out of the box that allow me to just start coding the main part of my app. Things like webpack configuration, getServerSideProps, and Netlify’s automatic creation of serverless functions are a few examples.

Netlify also makes deploying a Next.js git repo super easy. More on the deployment a bit later on.

What we’re building

Basically, we are going to build a trivia game that randomly shows you the name of a tennis player and you have to guess what country they are from. It consists of five rounds and keeps a running score of how many you get correct.

The data we need for this application is a list of players along with their country. Initially, I was thinking of querying some live API, but on second thought, decided to just use a local JSON file. I took a snapshot from RapidAPI and have included it in the starter repo.

The final product looks something like this:

You can find the final deployed version on Netlify.

Starter repo tour

If you want to follow along you can clone this repository and then go to the start branch:

git clone git@github.com:brenelz/tennis-trivia.git cd tennis-trivia git checkout start

In this starter repo, I went ahead and wrote some boilerplate to get things going. I created a Next.js app using the command npx create-next-app tennis-trivia. I then proceeded to manually change a couple JavaScript files to .ts and .tsx. Surprisingly, Next.js automatically picked up that I wanted to use TypeScript. It was too easy! I also went ahead and configured Tailwind CSS using this article as a guide.

Enough talk, let’s code!

Initial setup

The first step is setting up environment variables. For local development, we do this with a .env.local file. You can copy the .env.sample from the starter repo.

cp .env.sample .env.local

Notice it currently has one value, which is the path of our application. We will use this on the front end of our app, so we must prefix it with NEXT_PUBLIC_.

Finally, let’s use the following commands to install the dependencies and start the dev server: 

npm install npm run dev

Now we access our application at http://localhost:3000. We should see a fairly empty page with just a headline:

Creating the UI markup

In pages/index.tsx, let’s add the following markup to the existing Home() function:

export default function Home() {   return (     <div className="bg-blue-500">     <div className="max-w-2xl mx-auto text-center py-16 px-4 sm:py-20 sm:px-6 lg:px-8">       <h2 className="text-3xl font-extrabold text-white sm:text-4xl">         <span className="block">Tennis Trivia - Next.js Netlify</span>       </h2>       <div>         <p className="mt-4 text-lg leading-6 text-blue-200">           What country is the following tennis player from?         </p>         <h2 className="text-lg font-extrabold text-white my-5">           Roger Federer         </h2>          <form>           <input             list="countries"             type="text"             className="p-2 outline-none"             placeholder="Choose Country"           />           <datalist id="countries">             <option>Switzerland</option>            </datalist>            <p>              <button                className="mt-8 w-full inline-flex items-center justify-center px-5 py-3 border border-transparent text-base font-medium rounded-md text-blue-600 bg-white hover:bg-blue-50 sm:w-auto"                type="submit"              >                Guess             </button>           </p>         </form>          <p className="mt-4 text-lg leading-6 text-white">           <strong>Current score:</strong> 0         </p>       </div>     </div>     </div>   );

This forms the scaffold for our UI. As you can see, we are using lots of utility classes from Tailwind CSS to make things look a little prettier. We also have a simple autocomplete input and a submit button. This is where you will select the country you think the player is from and then hit the button. Lastly, at the bottom, there is a score that changes based on correct or incorrect answers.

Setting up our data

If you take a look at the data folder, there should be a tennisPlayers.json with all the data we will need for this application. Create a lib folder at the root and, inside of it, create a players.ts file. Remember, the .ts extension is required since is a TypeScript file. Let’s define a type that matches our JSON data..

export type Player = {   id: number,   first_name: string,   last_name: string,   full_name: string,   country: string,   ranking: number,   movement: string,   ranking_points: number, };

This is how we create a type in TypeScript. We have the name of the property on the left, and the type it is on the right. They can be basic types, or even other types themselves.

From here, let’s create specific variables that represent our data:

export const playerData: Player[] = require("../data/tennisPlayers.json"); export const top100Players = playerData.slice(0, 100);  const allCountries = playerData.map((player) => player.country).sort(); export const uniqueCountries = [...Array.from(new Set(allCountries))];

A couple things to note is that we are saying our playerData is an array of Player types. This is denoted by the colon followed by the type. In fact, if we hover over the playerData we can see its type:

In that last line we are getting a unique list of countries to use in our country dropdown. We pass our countries into a JavaScript Set, which gets rid of the duplicate values. We then create an array from it, and spread it into a new array. It may seem unnecessary but this was done to make TypeScript happy.

Believe it or not, that is really all the data we need for our application!

Let’s make our UI dynamic!

All our values are hardcoded currently, but let’s change that. The dynamic pieces are the tennis player’s name, the list of countries, and the score.

Back in pages/index.tsx, let’s modify our getServerSideProps function to create a list of five random players as well as pull in our uniqueCountries variable.

import { Player, uniqueCountries, top100Players } from "../lib/players"; ... export async function getServerSideProps() {   const randomizedPlayers = top100Players.sort((a, b) => 0.5 - Math.random());   const players = randomizedPlayers.slice(0, 5);    return {     props: {       players,       countries: uniqueCountries,     },   }; }

Whatever is in the props object we return will be passed to our React component. Let’s use them on our page:

type HomeProps = {   players: Player[];   countries: string[]; };  export default function Home({ players, countries }: HomeProps) {   const player = players[0];   ... }  

As you can see, we define another type for our page component. Then we add the HomeProps type to the Home() function. We have again specified that players is an array of the Player type.

Now we can use these props further down in our UI. Replace “Roger Federer” with {player.full_name} (he’s my favorite tennis player by the way). You should be getting nice autocompletion on the player variable as it lists all the property names we have access to because of the types that we defined.

Further down from this, let’s now update the list of countries to this:

<datalist id="countries">   {countries.map((country, i) => (     <option key={i}>{country}</option>   ))} </datalist>

Now that we have two of the three dynamic pieces in place, we need to tackle the score. Specifically, we need to create a piece of state for the current score.

export default function Home({ players, countries }: HomeProps) {   const [score, setScore] = useState(0);   ... }

Once this is done, replace the 0 with {score} in our UI.

You can now check our progress by going to http://localhost:3000. You can see that every time the page refreshes, we get a new name; and when typing in the input field, it lists all of the available unique countries.

Adding some interactivity

We’ve come a decent way but we need to add some interactivity.

Hooking up the guess button

For this we need to have some way of knowing what country was picked. We do this by adding some more state and attaching it to our input field.

export default function Home({ players, countries }: HomeProps) {   const [score, setScore] = useState(0);   const [pickedCountry, setPickedCountry] = useState("");   ...   return (     ...     <input       list="countries"       type="text"       value={pickedCountry}       onChange={(e) => setPickedCountry(e.target.value)}       className="p-2 outline-none"       placeholder="Choose Country"     />    ...   ); }

Next, let’s add a guessCountry function and attach it to the form submission:

const guessCountry = () => {   if (player.country.toLowerCase() === pickedCountry.toLowerCase()) {     setScore(score + 1);   } else {     alert(‘incorrect’);   } }; ... <form   onSubmit={(e) => {     e.preventDefault();     guessCountry();   }} >

All we do is basically compare the current player’s country to the guessed country. Now, when we go back to the app and guess the country right, the score increases as expected.

Adding a status indicator

To make this a bit nicer, we can render some UI depending whether the guess is correct or not.

So, let’s create another piece of state for status, and update the guess country method:

const [status, setStatus] = useState(null); ... const guessCountry = () => {   if (player.country.toLowerCase() === pickedCountry.toLowerCase()) {     setStatus({ status: "correct", country: player.country });     setScore(score + 1);   } else {     setStatus({ status: "incorrect", country: player.country });   } };

Then render this UI below the player name:

{status && (   <div className="mt-4 text-lg leading-6 text-white">     <p>             You are {status.status}. It is {status.country}     </p>     <p>       <button         autoFocus         className="outline-none mt-8 w-full inline-flex items-center justify-center px-5 py-3 border border-transparent text-base font-medium rounded-md text-blue-600 bg-white hover:bg-blue-50 sm:w-auto"       >         Next Player       </button>     </p>   </div> )}

Lastly, we want to make sure our input field doesn’t show when we are in a correct or incorrect status. We achieve this by wrapping the form with the following:

{!status && (   <form>   ...   </form> )}

Now, if we go back to the app and guess the player’s country, we get a nice message with the result of the guess.

Progressing through players

Now probably comes the most challenging part: How do we go from one player to the next?

First thing we need to do is store the currentStep in state so that we can update it with a number from 0 to 4. Then, when it hits 5, we want to show a completed state since the trivia game is over.

Once again, let’s add the following state variables:

const [currentStep, setCurrentStep] = useState(0); const [playersData, setPlayersData] = useState(players);

…then replace our previous player variable with:

const player = playersData[currentStep];

Next, we create a nextStep function and hook it up to the UI:

const nextStep = () => {   setPickedCountry("");   setCurrentStep(currentStep + 1);   setStatus(null); }; ... <button   autoFocus   onClick={nextStep}   className="outline-none mt-8 w-full inline-flex items-center justify-center px-5 py-3 border border-transparent text-base font-medium rounded-md text-blue-600 bg-white hover:bg-blue-50 sm:w-auto"  >     Next Player </button>

Now, when we make a guess and hit the next step button, we’re taken to a new tennis player. Guess again and we see the next, and so on. 

What happens when we hit next on the last player? Right now, we get an error. Let’s fix that by adding a conditional that represents that the game has been completed. This happens when the player variable is undefined.

{player ? (   <div>     <p className="mt-4 text-lg leading-6 text-blue-200">       What country is the following tennis player from?     </p>     ...     <p className="mt-4 text-lg leading-6 text-white">       <strong>Current score:</strong> {score}     </p>   </div> ) : (   <div>     <button       autoFocus       className="outline-none mt-8 w-full inline-flex items-center justify-center px-5 py-3 border border-transparent text-base font-medium rounded-md text-indigo-600 bg-white hover:bg-indigo-50 sm:w-auto"       >       Play Again     </button>   </div> )}

Now we see a nice completed state at the end of the game.

Play again button

We are almost done! For our “Play Again” button we want to reset the state all of the game. We also want to get a new list of players from the server without needing a refresh. We do it like this:

const playAgain = async () => {   setPickedCountry("");   setPlayersData([]);   const response = await fetch(     process.env.NEXT_PUBLIC_API_URL + "/api/newGame"   );   const data = await response.json();   setPlayersData(data.players);   setCurrentStep(0);   setScore(0); };  <button   autoFocus   onClick={playAgain}   className="outline-none mt-8 w-full inline-flex items-center justify-center px-5 py-3 border border-transparent text-base font-medium rounded-md text-indigo-600 bg-white hover:bg-indigo-50 sm:w-auto" >   Play Again </button>

Notice we are using the environment variable we set up before via the process.env object. We are also updating our playersData by overriding our server state with our client state that we just retrieved.

We haven’t filled out our newGame route yet, but this is easy with Next.js and Netlify serverless functions . We only need to edit the file in pages/api/newGame.ts.

import { NextApiRequest, NextApiResponse } from "next" import { top100Players } from "../../lib/players";  export default (req: NextApiRequest, res: NextApiResponse) => {   const randomizedPlayers = top100Players.sort((a, b) => 0.5 - Math.random());   const top5Players = randomizedPlayers.slice(0, 5);   res.status(200).json({players: top5Players}); }

This looks much the same as our getServerSideProps because we can reuse our nice helper variables.

If we go back to the app, notice the “Play Again” button works as expected.

Improving focus states

One last thing we can do to improve our user experience is set the focus on the country input field every time the step changes. That’s just a nice touch and convenient for the user. We do this using a ref and a useEffect:

const inputRef = useRef(null); ... useEffect(() => {   inputRef?.current?.focus(); }, [currentStep]);  <input   list="countries"   type="text"   value={pickedCountry}   onChange={(e) => setPickedCountry(e.target.value)}   ref={inputRef}   className="p-2 outline-none"   placeholder="Choose Country" />

Now we can navigate much easier just using the Enter key and typing a country.

Deploying to Netlify

You may be wondering how we deploy this thing. Well, using Netlify makes it so simple as it detects a Next.js application out of the box and automatically configures it.

All I did was set up a GitHub repo and connect my GitHub account to my Netlify account. From there, I simply pick a repo to deploy and use all the defaults.

The one thing to note is that you have to add the NEXT_PUBLIC_API_URL environment variable and redeploy for it to take effect.

You can find my final deployed version here.

Also note that you can just hit the “Deploy to Netlify” button on the GitHub repo.


Woohoo, you made it! That was a journey and I hope you learned something about React, Next.js, and Netlify along the way.

I have plans to expand this tennis trivia app to use Supabase in the near future so stay tuned!

Accessing Your Data With Netlify Functions and React

(This is a sponsored post.)

Static site generators are popular for their speed, security, and user experience. However, sometimes your application needs data that is not available when the site is built. React is a library for building user interfaces that helps you retrieve and store dynamic data in your client application. 

Fauna is a flexible, serverless database delivered as an API that completely eliminates operational overhead such as capacity planning, data replication, and scheduled maintenance. Fauna allows you to model your data as documents, making it a natural fit for web applications written with React. Although you can access Fauna directly via a JavaScript driver, this requires a custom implementation for each client that connects to your database. By placing your Fauna database behind an API, you can enable any authorized client to connect, regardless of the programming language.

Netlify Functions allow you to build scalable, dynamic applications by deploying server-side code that works as API endpoints. In this tutorial, you build a serverless application using React, Netlify Functions, and Fauna. You learn the basics of storing and retrieving your data with Fauna. You create and deploy Netlify Functions to access your data in Fauna securely. Finally, you deploy your React application to Netlify.

Getting started with Fauna

Fauna is a distributed, strongly consistent OLTP NoSQL serverless database that is ACID-compliant and offers a multi-model interface. Fauna also supports document, relational, graph, and temporal data sets from a single query. First, we will start by creating a database in the Fauna console by selecting the Database tab and clicking on the Create Database button.

Next, you will need to create a Collection. For this, you will need to select a database, and under the Collections tab, click on Create Collection.

Fauna uses a particular structure when it comes to persisting data. The design consists of attributes like the example below.

{   "ref": Ref(Collection("avengers"), "299221087899615749"),   "ts": 1623215668240000,   "data": {     "id": "db7bd11d-29c5-4877-b30d-dfc4dfb2b90e",     "name": "Captain America",     "power": "High Strength",     "description": "Shield"   } }

Notice that Fauna keeps a ref column which is a unique identifier used to identify a particular document. The ts attribute is a timestamp to determine the time of creating the record and the data attribute responsible for the data.

Why creating an index is important

Next, let’s create two indexes for our avengers collection. This will be pretty valuable in the latter part of the project. You can create an index from the Index tab or from the Shell tab, which provides a console to execute scripts. Fauna supports two types of querying techniques: FQL (Fauna’s Query language) and GraphQL. FQL operates based on the schema of Fauna, which includes documents, collections, indexes, sets, and databases. 

Let’s create the indexes from the shell.

This command will create an index on the Collection, which will create an index by the id field inside the data object. This index will return a ref of the data object. Next, let’s create another index for the name attribute and name it avenger_by_name.

Creating a server key

To create a server key, we need to navigate the Security tab and click on the New Key button. This section will prompt you to create a key for a selected database and the user’s role.

Getting started with Netlify functions and React

In this section, we’ll see how we create Netlify functions with React. We will be using create-react-app to create the react app.

npx create-react-app avengers-faunadb

After creating the react app, let’s install some dependencies, including Fauna and Netlify dependencies.

yarn add axios bootstrap node-sass uuid faunadb react-netlify-identity react-netlify-identity-widget

Now let’s create our first Netlfiy function. To make the functions, first, we need to install Netlifiy CLI globally.

npm install netlify-cli -g

Now that the CLI is installed, let’s create a .env file on our project root with the following fields.

FAUNADB_SERVER_SECRET= <FaunaDB secret key> REACT_APP_NETLIFY= <Netlify app url>

Next, Let’s see how we can start with creating netlify functions. For this, we will need to create a directory in our project root called functions and a file called netlify.toml, which will be responsible for maintaining configurations for our Netlify project. This file defines our function’s directory, build directory, and commands to execute.

[build] command = "npm run build" functions = "functions/" publish = "build"  [[redirects]]   from = "/api/*"   to = "/.netlify/functions/:splat"   status = 200   force = true

We will do some additional configuration for the Netlify configuration file, like in the redirection section in this example. Notice that we are changing the default path of the Netlify function of /.netlify/** to /api/. This configuration is mainly for the improvement of the look and field of the API URL. So to trigger or call our function, we can use the path:


 …instead of:


Next, let’s create our Netlify function in the functions directory. But, first, let’s make a connection file for Fauna called util/connections.js, returning a Fauna connection object.

const faunadb = require('faunadb'); const q = faunadb.query  const clientQuery = new faunadb.Client({   secret: process.env.FAUNADB_SERVER_SECRET, });  module.exports = { clientQuery, q };

Next, let’s create a helper function checking for reference and returning since we will need to parse the data on several occasions throughout the application. This file will be util/helper.js.

const responseObj = (statusCode, data) => {   return {     statusCode: statusCode,     headers: {      /* Required for CORS support to work */       "Access-Control-Allow-Origin": "*",       "Access-Control-Allow-Headers": "*",       "Access-Control-Allow-Methods": "GET, POST, OPTIONS",     },    body: JSON.stringify(data)   }; };  const requestObj = (data) => {   return JSON.parse(data); }  module.exports = { responseObj: responseObj, requestObj: requestObj }

Notice that the above helper functions handle the CORS issues, stringifying and parsing of JSON data. Let’s create our first function, getAvengers, which will return all the data.

const { responseObj } = require('./util/helper'); const { q, clientQuery } = require('./util/connection');  exports.handler = async (event, context) => {   try {    let avengers = await clientQuery.query(      q.Map(        q.Paginate(q.Documents(q.Collection('avengers'))),        q.Lambda(x => q.Get(x))       )     )     return responseObj(200, avengers)   } catch (error) {     console.log(error)     return responseObj(500, error);   } };

In the above code example, you can see that we have used several FQL commands like Map, Paginate, Lamda. The Map key is used to iterate through the array, and it takes two arguments: an Array and Lambda. We have passed the Paginate for the first parameter, which will check for reference and return a page of results (an array). Next, we used a Lamda statement, an anonymous function that is quite similar to an anonymous arrow function in ES6.

Next, Let’s create our function AddAvenger responsible for creating/inserting data into the Collection.

const { requestObj, responseObj } = require('./util/helper'); const { q, clientQuery } = require('./util/connection');  exports.handler = async (event, context) => {   let data = requestObj(event.body);    try {     let avenger = await clientQuery.query(       q.Create(         q.Collection('avengers'),         {           data: {             id: data.id,             name: data.name,             power: data.power,             description: data.description           }         }       )     );      return responseObj(200, avenger)   } catch (error) {     console.log(error)     return responseObj(500, error);   }   };

To save data for a particular collection, we will have to pass, or data to the data:{} object like in the above code example. Then we need to pass it to the Create function and point it to the collection you want and the data. So, let’s run our code and see how it works through the netlify dev command.

Let’s trigger the GetAvengers function through the browser through the URL http://localhost:8888/api/GetAvengers.

The above function will fetch the avenger object by the name property searching from the avenger_by_name index. But, first, let’s invoke the GetAvengerByName function through a Netlify function. For that, let’s create a function called SearchAvenger.

const { responseObj } = require('./util/helper'); const { q, clientQuery } = require('./util/connection');  exports.handler = async (event, context) => {   const {     queryStringParameters: { name },   } = event;    try {     let avenger = await clientQuery.query(       q.Call(q.Function("GetAvengerByName"), [name])     );     return responseObj(200, avenger)   } catch (error) {     console.log(error)     return responseObj(500, error);   } };

Notice that the Call function takes two arguments where the first parameter will be the reference for the FQL function that we created and the data that we need to pass to the function.

Calling the Netlify function through React

Now that several functions are available let’s consume those functions through React. Since the functions are REST APIs, let’s consume them via Axios, and for state management, let’s use React’s Context API. Let’s start with the Application context called AppContext.js.

import { createContext, useReducer } from "react"; import AppReducer from "./AppReducer"  const initialState = {     isEditing: false,     avenger: { name: '', description: '', power: '' },     avengers: [],     user: null,     isLoggedIn: false };  export const AppContext = createContext(initialState);  export const AppContextProvider = ({ children }) => {     const [state, dispatch] = useReducer(AppReducer, initialState);      const login = (data) => { dispatch({ type: 'LOGIN', payload: data }) }     const logout = (data) => { dispatch({ type: 'LOGOUT', payload: data }) }     const getAvenger = (data) => { dispatch({ type: 'GET_AVENGER', payload: data }) }     const updateAvenger = (data) => { dispatch({ type: 'UPDATE_AVENGER', payload: data }) }     const clearAvenger = (data) => { dispatch({ type: 'CLEAR_AVENGER', payload: data }) }     const selectAvenger = (data) => { dispatch({ type: 'SELECT_AVENGER', payload: data }) }     const getAvengers = (data) => { dispatch({ type: 'GET_AVENGERS', payload: data }) }     const createAvenger = (data) => { dispatch({ type: 'CREATE_AVENGER', payload: data }) }     const deleteAvengers = (data) => { dispatch({ type: 'DELETE_AVENGER', payload: data }) }      return <AppContext.Provider value={{         ...state,         login,         logout,         selectAvenger,         updateAvenger,         clearAvenger,         getAvenger,         getAvengers,         createAvenger,         deleteAvengers     }}>{children}</AppContext.Provider> }  export default AppContextProvider;

Let’s create the Reducers for this context in the AppReducer.js file, Which will consist of a reducer function for each operation in the application context.

const updateItem = (avengers, data) => {     let avenger = avengers.find((avenger) => avenger.id === data.id);     let updatedAvenger = { ...avenger, ...data };     let avengerIndex = avengers.findIndex((avenger) => avenger.id === data.id);     return [         ...avengers.slice(0, avengerIndex),         updatedAvenger,         ...avengers.slice(++avengerIndex),     ]; }  const deleteItem = (avengers, id) => {     return avengers.filter((avenger) => avenger.data.id !== id) }  const AppReducer = (state, action) => {     switch (action.type) {         case 'SELECT_AVENGER':             return {                 ...state,                 isEditing: true,                 avenger: action.payload             }         case 'CLEAR_AVENGER':             return {                 ...state,                 isEditing: false,                 avenger: { name: '', description: '', power: '' }             }         case 'UPDATE_AVENGER':             return {                 ...state,                 isEditing: false,                 avengers: updateItem(state.avengers, action.payload)             }         case 'GET_AVENGER':             return {                 ...state,                 avenger: action.payload.data             }         case 'GET_AVENGERS':             return {                 ...state,                 avengers: Array.isArray(action.payload && action.payload.data) ? action.payload.data : [{ ...action.payload }]             };         case 'CREATE_AVENGER':             return {                 ...state,                 avengers: [{ data: action.payload }, ...state.avengers]             };         case 'DELETE_AVENGER':             return {                 ...state,                 avengers: deleteItem(state.avengers, action.payload)             };         case 'LOGIN':             return {                 ...state,                 user: action.payload,                 isLoggedIn: true             };         case 'LOGOUT':             return {                 ...state,                 user: null,                 isLoggedIn: false             };         default:             return state     } }  export default AppReducer; 

Since the application context is now available, we can fetch data from the Netlify functions that we have created and persist them in our application context. So let’s see how to call one of these functions.

const { avengers, getAvengers } = useContext(AppContext);  const GetAvengers = async () => {   let { data } = await axios.get('/api/GetAvengers);   getAvengers(data) }

To get the data to the application contexts, let’s import the function getAvengers from our application context and pass the data fetched by the get call. This function will call the reducer function, which will keep the data in the context. To access the context, we can use the attribute called avengers. Next, let’s see how we could save data on the avengers collection.

const { createAvenger } = useContext(AppContext);  const CreateAvenger = async (e) => {   e.preventDefault();   let new_avenger = { id: uuid(), ...newAvenger }   await axios.post('/api/AddAvenger', new_avenger);   clear();   createAvenger(new_avenger) }

The above newAvenger object is the state object which will keep the form data. Notice that we pass a new id of type uuid to each of our documents. Thus, when the data is saved in Fauna, We will be using the createAvenger function in the application context to save the data in our context. Similarly, we can invoke all the netlify functions with CRUD operations like this via Axios.

How to deploy the application to Netlify

Now that we have a working application, we can deploy this app to Netlify. There are several ways that we can deploy this application:

  1. Connecting and deploying the application through GitHub
  2. Deploying the application through the Netlify CLI

Using the CLI will prompt you to enter specific details and selections, and the CLI will handle the rest. But in this example, we will be deploying the application through Github. So first, let’s log in to the Netlify dashboard and click on New Site from Git button. Next, It will prompt you to select the Repo you need to deploy and the configurations for your site like build command, build folder, etc.

How to authenticate and authorize functions by Netlify Identity

Netlify Identity provides a full suite of authentication functionality to your application which will help us to manage authenticated users throughout the application. Netlify Identity can be integrated easily into the application without using any other 3rd party service and libraries. To enable Netlify Identity, we need to login into our Neltify dashboard, and under our deployed site, we need to move to the Identity tab and allow the identity feature.

Enabling Identity will provide a link to your netlify identity. You will have to copy that URL and add it to the .env file of your application for REACT_APP_NETLIFY. Next, We need to add the Netlify Identity to our React application through the netlify-identity-widget and the Netlify functions. But, first, let’s add the REACT_APP_NETLIFY property for the Identity Context Provider component in the index.js file.

import React from 'react'; import ReactDOM from 'react-dom'; import './index.css'; import "react-netlify-identity-widget/styles.css" import 'bootstrap/dist/css/bootstrap.css'; import App from './App'; import { IdentityContextProvider } from "react-netlify-identity-widget" const url = process.env.REACT_APP_NETLIFY;  ReactDOM.render(   <IdentityContextProvider url=https://css-tricks.com/accessing-data-netlify-functions-react/>     <App />   </IdentityContextProvider>,   document.getElementById('root') );

This component is the Navigation bar that we use in this application. This component will be on top of all the other components to be the ideal place to handle the authentication. This react-netlify-identity-widget will add another component that will handle the user signI= in and sign up.

Next, let’s use the Identity in our Netlify functions. Identity will introduce some minor modifications to our functions, like the below function GetAvenger.

const { responseObj } = require('./util/helper'); const { q, clientQuery } = require('./util/connection');  exports.handler = async (event, context) => {     if (context.clientContext.user) {         const {             queryStringParameters: { id },         } = event;         try {             const avenger = await clientQuery.query(                 q.Get(                     q.Match(q.Index('avenger_by_id'), id)                 )             );             return responseObj(200, avenger)         } catch (error) {             console.log(error)             return responseObj(500, error);         }     } else {         return responseObj(401, 'Unauthorized');     } };

The context of each request will consist of a property called clientContext, which will consist of authenticated user details. In the above example, we use a simple if condition to check the user context. 

To get the clientContext in each of our requests, we need to pass the user token through the Authorization Headers. 

const { user } = useIdentityContext();  const GetAvenger = async (id) => {   let { data } = await axios.get('/api/GetAvenger/?id=' + id, user && {     headers: {       Authorization: `Bearer $ {user.token.access_token}`     }   });   getAvenger(data) }

This user token will be available in the user context once logged in to the application through the netlify identity widget.

As you can see, Netlify functions and Fauna look to be a promising duo for building serverless applications. You can follow this GitHub repo for the complete code and refer to this URL for the working demo.


In conclusion, Fauna and Netlify look to be a promising duo for building serverless applications. Netlify also provides the flexibility to extend its functionality through the plugins to enhance the experience. The pricing plan with pay as you go is ideal for developers to get started with fauna. Fauna is extremely fast, and it auto-scales so that developers will have the time to focus on their development more than ever. Fauna can handle complex database operations where you would find in Relational, Document, Graph, Temporal databases. Fauna Driver support all the major languages such as Android, C#, Go, Java, JavaScript, Python, Ruby, Scala, and Swift. With all these excellent features, Fauna looks to be one of the best Serverless databases. For more information, go through Fauna documentation.

Hack the “Deploy to Netlify” Button Using Environment Variables to Make a Customizable Site Generator

If you’re anything like me, you like being lazy shortcuts. The “Deploy to Netlify” button allows me to take this lovely feature of my personality and be productive with it.

Deploy to Netlify

Clicking the button above lets me (or you!) instantly clone my Next.js starter project and automatically deploy it to Netlify. Wow! So easy! I’m so happy!

Now, as I was perusing the docs for the button the other night, as one does, I noticed that you can pre-fill environment variables to the sites you deploy with the button. Which got me thinking… what kind of sites could I customize with that?

Ah, the famed “link in bio” you see all over social media when folks want you to see all of their relevant links in life. You can sign up for the various services that’ll make one of these sites for you, but what if you could make one yourself without having to sign up for yet another service?

But, we also are lazy and like shortcuts. Sounds like we can solve all of these problems with the “Deploy to Netlify” (DTN) button, and environment variables.

How would we build something like this?

In order to make our DTN button work, we need to make two projects that work together:

  • A template project (This is the repo that will be cloned and customized based on the environment variables passed in.)
  • A generator project (This is the project that will create the environment variables that should be passed to the button.)

I decided to be a little spicy with my examples, and so I made both projects with Vite, but the template project uses React and the generator project uses Vue.

I’ll do a high-level overview of how I built these two projects, and if you’d like to just see all the code, you can skip to the end of this post to see the final repositories!

The Template project

To start my template project, I’ll pull in Vite and React.

npm init @vitejs/app

After running this command, you can follow the prompts with whatever frameworks you’d like!

Now after doing the whole npm install thing, you’ll want to add a .local.env file and add in the environment variables you want to include. I want to have a name for the person who owns the site, their profile picture, and then all of their relevant links.

You can set this up however you’d like, because this is just test data we’ll build off of! As you build out your own application, you can pull in your environment variables at any time for parsing with import.meta.env. Vite lets you access those variables from the client code with VITE_, so as you play around with variables, make sure you prepend that to your variables.

Ultimately, I made a rather large parsing function that I passed to my components to render into the template:

function getPageContent() {   // Pull in all variables that start with VITE_ and turn it into an array   let envVars = Object.entries(import.meta.env).filter((key) => key[0].startsWith('VITE_'))    // Get the name and profile picture, since those are structured differently from the links   const name = envVars.find((val) => val[0] === 'VITE_NAME')[1].replace(/_/g, ' ')   const profilePic = envVars.find((val) => val[0] === 'VITE_PROFILE_PIC')[1]      // ...      // Pull all of the links, and properly format the names to be all lowercase and normalized   let links = envVars.map((k) => {     return [deEnvify(k[0]), k[1]]   })    // This object is what is ultimately sent to React to be rendered   return { name, profilePic, links } }  function deEnvify(str) {   return str.replace('VITE_', '').replace('_LINK', '').toLowerCase().split('_').join(' ') }

I can now pull in these variables into a React function that renders the components I need:

// ...   return (     <div>       <img alt={vars.name} src={vars.profilePic} />       <p>{vars.name}</p>       {vars.links.map((l, index) => {         return <Link key={`link$ {index}`} name={l[0]} href={l[1]} />       })}     </div>   )  // ...

And voilà! With a little CSS, we have a “link in bio” site!

Now let’s turn this into something that doesn’t rely on hard-coded variables. Generator time!

The Generator project

I’m going to start a new Vite site, just like I did before, but I’ll be using Vue for this one, for funzies.

Now in this project, I need to generate the environment variables we talked about above. So we’ll need an input for the name, an input for the profile picture, and then a set of inputs for each link that a person might want to make.

In my App.vue template, I’ll have these separated out like so:

<template>   <div>     <p>       <span>Your name:</span>       <input type="text" v-model="name" /> 	</p>     <p>       <span>Your profile picture:</span>	       <input type="text" v-model="propic" />     </p>   </div>    <List v-model:list="list" />    <GenerateButton :name="name" :propic="propic" :list="list" /> </template>

In that List component, we’ll have dual inputs that gather all of the links our users might want to add:

<template>   <div class="list">     Add a link: <br />     <input type="text" v-model="newItem.name" />     <input type="text" v-model="newItem.url" @keyup.enter="addItem" />     <button @click="addItem">+</button>      <ListItem       v-for="(item, index) in list"       :key="index"       :item="item"       @delete="removeItem(index)"     />   </div> </template>

So in this component, there’s the two inputs that are adding to an object called newItem, and then the ListItem component lists out all of the links that have been created already, and each one can delete itself.

Now, we can take all of these values we’ve gotten from our users, and populate the GenerateButton component with them to make our DTN button work!

The template in GenerateButton is just an <a> tag with the link. The power in this one comes from the methods in the <script>.

// ... methods: {   convertLink(str) {     // Convert each string passed in to use the VITE_WHATEVER_LINK syntax that our template expects     return `VITE_$ {str.replace(/ /g, '_').toUpperCase()}_LINK`   },   convertListOfLinks() {     let linkString = ''          // Pass each link given by the user to our helper function     this.list.forEach((l) => {       linkString += `$ {this.convertLink(l.name)}=$ {l.url}&`     })      return linkString   },   // This function pushes all of our strings together into one giant link that will be put into our button that will deploy everything!   siteLink() {     return (       // This is the base URL we need of our template repo, and the Netlify deploy trigger       'https://app.netlify.com/start/deploy?repository=https://github.com/cassidoo/link-in-bio-template#' +       'VITE_NAME=' +       // Replacing spaces with underscores in the name so that the URL doesn't turn that into %20       this.name.replace(/ /g, '_') +       '&' +       'VITE_PROFILE_PIC=' +       this.propic +       '&' +       // Pulls all the links from our helper function above       this.convertListOfLinks()     )   }, }, 

Believe it or not, that’s it. You can add whatever styles you like or change up what variables are passed (like themes, toggles, etc.) to make this truly customizable!

Put it all together

Once these projects are deployed, they can work together in beautiful harmony!

This is the kind of project that can really illustrate the power of customization when you have access to user-generated environment variables. It may be a small one, but when you think about generating, say, resume websites, e-commerce themes, “/uses” websites, marketing sites… the possibilities are endless for turning this into a really cool boilerplate method.

Why Netlify?

I think it’s fair to think of Netlify as a CDN-backed static file host. But it would also be silly to think that’s all it is. That’s why I think it’s smart for them to have pages like this, comparing Netlify to GitHub Pages. GitHub Pages is a lot closer to only being a static file host. That’s still nice, but Netlify just brings so much more to the table.

Need to add a functional form to the site? Netlify does that.

Need to roll back to a previous version without any git-fu? Netlify does that.

Need to make sure you’re caching assets the best you can and breaking that cache for new versions? Netlify does that.

Need a preview of a pull request before you merge it? Netlify does that.

Need to set up redirects and rewrite rules so that your SPA behaves correctly? Netlify does that.

Need to run some server-side code? Netlify does that.

Need to do some A/B testing? Netlify does that.

That’s not all, just a random spattering of Netlify’s many features that take it to another level of hosting with a developer experience that’s beyond a static file host.

This same kind of thing came up on ShopTalk the other week. Why pick Netlify when you can toss files in a S3 bucket with Cloudfront in front of it? It’s a fair question, as maybe the outcome isn’t that different. But there are 100 other things to think about that, once you do, make Netlify seem like a no-brainer.

Next.js on Netlify

(This is a sponsored post.)

If you want to put Next.js on Netlify, here’s a 5 minute tutorial¹. One of the many strengths of Next.js is that it can do server-side rendering (SSR) with a Node server behind it. But Netlify does static hosting not Node hosting, right? Well Netlify has functions, and those functions can handle the SSR. But you don’t even really need to know that, you can just use the plugin.

Need a little bit more hand-holding than that? You got it, Cassidy is doing a free Webinar about all the next Thursday (March 4th, 2021) at 9am Pacific. That way you can watch live and ask questions and stuff. Netlify has a bunch of webinars they have now smartly archived on a new resources site.

  1. I’ve also mentioned this before if it sounds familiar, the fact that it supports the best of the entire rendering spectrum is very good.

High five to Netlify for the ❥ sponsorship. Netlify is a great place to host your static (or not-so-static!) website because of the great speed, DX, pricing, and feature set. I’ve thought of Netlify a bunch of times just in the past week or so, because either they release something cool, or someone else is writing about it.
