Question

Setting up Tailwind CSS in a Rspack project.

• Using React

• Using Vue

1. Create your project

   Start by creating a new Rspack project if you don’t have one set up already. The most common approach is to use Rspack CLI.

   Terminal

   npm create rspack@latest

2. Install Tailwind CSS

   Install tailwindcss and its peer dependencies, then generate your tailwind.config.js and postcss.config.js files.

   Terminal

   npm install -D tailwindcss postcss postcss-loader autoprefixernpx tailwindcss init -p

3. Enable PostCSS support

   In your rspack.config.js file, enable the PostCSS loader. See the documentation for more information.

   rspack.config.js

   module.exports = {
     // ...
     module: {
       rules: [
         {
           test: /\.css$/,
           use: ["postcss-loader"],
           type: "css",
         },
     // ...
   

4. Configure your template paths

   Add the paths to all of your template files in your tailwind.config.js file.

   tailwind.config.js

   /** @type {import('tailwindcss').Config} */
   export default {
     content: [
       "./src/**/*.{js,ts,jsx,tsx}",
     ],
     theme: {
       extend: {},
     },
     plugins: [],
   }
   

5. Add the Tailwind directives to your CSS

   Add the @tailwind directives for each of Tailwind’s layers to your ./src/index.css file.

   index.css

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

6. Start your build process

   Run your build process with npm run dev.

   Terminal

   npm run dev

7. Start using Tailwind in your project

   Start using Tailwind’s utility classes to style your content.

   App.jsx

   export default function App() {
     return (
       <h1 className="text-3xl font-bold underline">
         Hello world!
       </h1>
     )
   }
