'NextJs Tailwind build (purge) removes all styling
In my current NextJS project, I am using Tailwind as a CSS framework. When I run yarn dev, everything works fine, but whenever I run yarn build followed by a yarn start, all of my CSS seems to be purged as the layout of my page is completely different.
Before:
After:
My tailwind.config.js file:
/* eslint-disable global-require */
const defaultTheme = require('tailwindcss/defaultTheme');
module.exports = {
purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
darkMode: false, // or 'media' or 'class'
theme: {
screens: {
sm: '640px',
md: '768px',
max_md: { max: '767px' },
lg: '1024px',
xl: '1536px',
},
colors: {
primary: '#f2a53f',
white: '#fff',
},
fontFamily: {
title: ['Dancing Script', 'Times New Roman', 'sans-serif'],
sans: ['Roboto', ...defaultTheme.fontFamily.sans],
},
textShadow: {
default: '1px 1px 3px #000',
},
zIndex: {
1: -1,
},
extend: {
height: {
128: '32rem',
},
margin: {},
},
},
variants: {
extend: {},
},
plugins: [require('tailwindcss-textshadow')],
};
postcss.config.js file:
const purgecss = [
'@fullhuman/postcss-purgecss',
{
content: [
'./pages/**/*.{js,jsx,ts,tsx}',
'./components/**/*.{js,jsx,ts,tsx}',
],
defaultExtractor: (content) => content.match(/[\w-/:]+(?<!:)/g) || [],
},
];
module.exports = {
plugins: [
'tailwindcss',
process.env.NODE_ENV === 'production' ? purgecss : undefined,
],
};
_app.tsx:
import Head from 'next/head';
import { ApolloProvider } from '@apollo/client';
import { AppProps } from 'next/app';
import { useApollo } from '../../apollo/client';
import '../styles/globals.css';
const MyApp = ({ Component, pageProps }: AppProps) => (
<ApolloProvider client={useApollo(pageProps.initialApolloState)}>
<Component {...pageProps} />
</ApolloProvider>
);
export default MyApp;
globals.css:
@tailwind base;
@tailwind components;
@tailwind utilities;
@font-face {
font-family: 'Dancing Script';
font-style: medium;
font-weight: 500;
font-display: swap;

If there is anything that seems off, feel free to let me know. I have looked at other issues online but did not find and solution to my problem.
Solution 1:[1]
Double check the paths in tailwind.config.js. If your components are not in the components directory, then you need to update the purge paths to reflect this.
Solution 2:[2]
I think I see the issue. @fullhuman/postcss-purgecss has been bundled with tailwindcss since v1.4 or so. Since it's manually declared in your postcss file as well, it's being executed twice which is wiping all of your styles. Also the fact that it only wipes your styles in production indicates that it is the culprit as execution of that particular package is dependent on process.env.NODE_ENV===production. Removing it from your postcss file should resolve your issue since it is already being executed under the hood by the tailwindcss bundle.
Here is my postcss with [email protected] for comparison:
postcss.config.js
module.exports = {
plugins: [
'postcss-import',
'tailwindcss',
'postcss-nesting',
'postcss-flexbugs-fixes',
[
'postcss-preset-env',
{
autoprefixer: {
flexbox: 'no-2009'
},
stage: 3,
features: {
'custom-properties': false,
'nesting-rules': true
}
}
]
]
};
One other possibility is that you aren't wrapping the paths/file-types targeted for purging within a top-level content object. From the code provided for your tailwind.config.js file:
module.exports = {
purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
//...
}
Here is my tailwind.config.js for cross-comparison
const defaultTheme = require('tailwindcss/defaultTheme');
module.exports = {
important: true,
purge: {
content: [
'./components/**/*.{js,ts,jsx,tsx}',
'./pages/**/*.{js,ts,jsx,tsx}'

If you're wondering why I use the postcss-import package before tailwindcss in my postcss.config.js, it's for separation of concerns and cleaner code. I have a top-level styles directory containing index.css, base.css, utilities.css, components.css, and chrome-bug.css. Their contents are as follows:
index.css
@import 'tailwindcss/base';
@import './base.css';
@import 'tailwindcss/components';

Next.js, How to setup tailwindcss with purge css to remove unused css
- install tailwindcss
yarn add -D tailwindcss
npx tailwindcss init
- configure your tailwind.config.js
module.exports = {
content: [
'./pages/**/*.{js,jsx,ts,tsx}',
'./components/**/*.{js,jsx,ts,tsx}'
],
theme: {
extend: {},
},
plugins: [],
}
- install purge css plugins
yarn add @fullhuman/postcss-purgecss postcss-preset-env
- configure postcss.config.js
module.exports = {
plugins: {
tailwindcss: {},
autoprefixer: {},
'@fullhuman/postcss-purgecss': {
content: [
'./pages/**/*.{js,jsx,ts,tsx}',
'./components/**/*.{js,jsx,ts,tsx}'
],
defaultExtractor: content => content.match(/[\w-/:]+(?<!:)/g) || []
},
'postcss-preset-env': {}
},
}
After that try adding a classname that you intentionally won't use and try to build for production and test from coverage tab that this classname is not loaded within source file
