Using Tailwind CSS with Enhance

Obviously, we are a bit biased around here, and we think that @enhance/styles is an excellent solution for styling your web application, but we acknowledge that there is more than one way to write an app. Plus, we ask you to learn a bunch of new ways of doing things when you build an Enhance app so you may feel comfortable with a different CSS utility framework.

Adding Tailwind CSS to your Enhance app

Many folks are familiar with Tailwind CSS, so we thought we’d give you a quick tutorial on setting it up in an Enhance context.

Step 1: Install arc-plugin-tailwind

The first step is to install arc-plugin-tailwind from community member @andybee.

npm i -D arc-plugin-tailwindcss

Do you know of other community-developed plugins needing more of a spotlight? Please let us know on Twitter.

Step 2: Add the plug-in to your .arc file

In your favorite text editor, open up the .arc as we will add a few lines to enable and configure the plugin.

First, in the @plugins section under the entry for enhance/arc-plugin-enhance add a new line for arc-plugin-tailwindcss as this will enable the plugin for the Enhance application. Then we’ll add a few more lines to configure the plugin.

  src my-styles.css
  build public/tailwind.css

The src line tells the plugin where to find the Tailwind CSS directives file. More on that in step 4. The build line specifies where the output of the Tailwind CSS build should live.

If you started with a default Enhance project, your .arc file should look like this:



  src my-styles.css
  build public/tailwind.css

Step 3: Create your tailwind.config.js file

At the root of your project, create a file called tailwind.config.js.We need to tell the Tailwind CSS compiler to look at all our .html and .mjs files in our app folder for utility classes. Any utility classes found in these files will be added to our public/tailwind.css file.

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./app/**/*.{html,mjs}"],
  theme: {
    extend: {},
  plugins: [],

Step 4: Create a Tailwind CSS directives file

In step 2, we told the Tailwind CSS plugin that the directives would be stored in my-styles.css, so let’s create that file and populate it with the following lines:

@tailwind base;
@tailwind components;
@tailwind utilities;

Step 5: Override the default Head component

Enhance provides a Head component that automatically includes @enhance/styles, but now we want to use Tailwind CSS instead. We’ll create a file named app/head.mjs and populate it with the following lines:

export default function Head() {
  return `
    <!DOCTYPE html>
    <html lang="en">
      <meta charset="utf-8">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <title>My Enhance Project</title>
      <link rel="stylesheet" href="/_static/tailwind.css">
      <link rel="icon" href="/_static/favicon.svg">

Whew, we are all done. Now, if you run npm start, you can develop your application locally using Tailwind CSS. Every time you edit a file under the app folder, arc-plugin-tailwind will automatically run the Tailwind CSS compiler and regenerate the public/tailwind.css file.

Example component

Create a new file app/elements/my-button.mjs with the contents:

export default function MyButton({ html }) {
  return html`
      <button class="text-white bg-indigo-500 border-0 py-2 px-8 focus:outline-none hover:bg-indigo-600 rounded text-lg">
        My Button

Check out how the file watcher automatically updates the tailwind.css file.

Happy styling!
