Cover Image for Next.js with Tailwind & TS


There a Repo with a template pre-made.

Setting up tailwind with Next.js & TypeScript can seem intimidating, but it's a fairly straightforward process once you have it all simplified.


yarn (or npm), Node.js 12+

App Setup

Firstly, we're going to setup our Next app & deps. This is as simple as running the following four commands

yarn create next-app my-app
cd my-app
touch tsconfig.json
yarn add typescript @types/node @types/react --dev

After this, you can rename the files under pages/ to end with .tsx, and the file under pages/api/ to hello.ts (although you can also delete it if you don't plan on using Now Functions.

When you start your app for the first time by running yarn dev, Next.js will populate your tsconfig.json, so you can leave it empty for now.

Finally, you can remove the styles folder, and change the import in _app.tsx to be import "tailwindcss/tailwind.css" instead. Remember to remove the import in index.tsx too.

Adding Tailwind

We need to install and setup tailwind and it's dependencies. We can do this by running these commands

yarn add tailwindcss@latest postcss@latest autoprefixer@latest --dev
npx tailwindcss init -p

This will create a tailwind.config.js as well as postcss.config.js. If you head to tailwind.config.js, we need to edit the value of purge to include our TypeScript content. This can be done by setting it to

module.exports = {
  purge: ["./pages/**/*.{ts,tsx}", "./components/**/*.{ts,tsx}"],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  variants: {
    extend: {},
  plugins: [],

And finally, our app is ready to start.
