How to use Tailwind with Create React App and PostCSS with no hassle

I really like styled components and CSS in JS in general, but this has quickly overtaken as my favourite way to do styling in React. It took a little while to figure out the configuration so I'm going to share that here.

The combination that works to make this seamless is as follows:

Getting set up

Using Create React App is very well documented. We'll start a new project and install our dev dependencies.

npx create-react-app cra-postcss-tailwind
cd cra-postcss-tailwind
yarn add -D @craco/craco autoprefixer postcss-nested tailwindcss

Setting up the basic webpack config

To allow us to customise the Create React App webpack config we'll be using Craco.

Create a tailwind.config.js file in the root of the project for whatever customisations you like. This is also where we set up the production purge to get rid of unused utilities and keep file size down.

module.exports = {
  purge: ["./src/**/*.html", "./src/**/*.jsx", "./src/**/*.js"],
  theme: {
    extend: {
      screens: {
        xs: { max: "400px" },

And create a craco.config.js file to set up the postcss plugins:

module.exports = {
  style: {
    postcss: {
      plugins: [require("tailwindcss")("./tailwind.config.js")],

Now let's change the scripts inside package.json to use craco instead of react-scripts. This is what allows us to bypass the restrictions with Create React App without ejecting.

"scripts": {
  "start": "craco start",
  "build": "craco build",
  "test": "craco test",

Finally, let's set up the global stylesheet. Adding to the start of src/index.css:

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

That's it for the basics, you should now be able to use tailwind in your markup with all the benefits of CRA with impunity. Let's run the project with yarn start and add a utility class to test it out:

Composition and modules

This setup comes with all the benefits of a normal CRA + PostCSS setup, which means we can compose classes inside CSS modules alongside regular CSS like this:

/* App.css */
.App {
  width: 100vw;
  height: 100vh;
  @apply bg-green-500;

And with the inclusion of the postcss-nested plugin we can have SASS style nesting as well:

// craco.config.js
/* App.css */
.App {
  width: 100vw;
  height: 100vh;
  @apply bg-green-500 flex items-center justify-center;

  &-inner {
    @apply bg-gray-900 text-white p-4;
// App.js
return (
  <div className="App">
    <div className="App-inner border border-white">Success!</div>

Resulting in this:

And that's it. This is definitely my new favourite way to do styling in React. Go to the repo
