Craft 3

Setting up TailwindCSS in Craft 3 is relatively simple. Navigate to your Craft project folder:

cd my-project.test

First thing we need to do is create a package.json file.

npm init

Follow the instructions and once it's done, the next step is to install Tailwind itself.

npm install tailwindcss

We then need to create a configuration file. To do this, run the following in your Craft project folder:

./node_modules/.bin/tailwind init

This will create the config file for called tailwind.config.js within your Craft project folder.

Because Craft doesn't come with a compilation tool built in, we need to install one. For this tutorial, we'll be using Laravel Mix, which is a wrapper built around Webpack. It's much easier to use and works great with Craft.

In your Craft project folder, install Laravel Mix:

npm install laravel-mix

For the sake of this example, we're going to create our CSS file in resources/css/app.css. This is in our Craft project folder, so it'll be something like my-project.test/resources/css/app.css.

In that file, add:

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

Now create a file called webpack.mix.js in your Craft project folder. In it, add the following:

const mix = require('laravel-mix');
const tailwindcss = require('tailwindcss');

mix.postCss('resources/css/app.css', 'web/css/app.css', [
        tailwindcss('tailwind.config.js')
    ]
);

We also need to install a package called cross-env. This is only really required if you're working on Windows.

npm install cross-env

Once you've done that, open your package.json file and add the following:

"scripts": {
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "npm run development -- --watch",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},

After you've done this, run npm run dev. This will output a your css file at web/css/app.css.

To hook this into your Craft 3 templates, simply add the following to your templates/_layout.html template:

<link rel="stylesheet" href="/css/app.css">

If you load your Craft project, you should now see the default styling.

Build once

npm run dev

Keep building

npm run watch
