nx - tailwindcss not working with next js - tailwind-css

Question

I Generate a new project with nx using nextjs preset. Then with the help of the nx dev blog post i setup tailwind css like following
postcss.config.js
const { join } = require('path');
module.exports = {
plugins: {
tailwindcss: { config: './apps/storefront/tailwind.config.js' },
// tailwindcss: {
// config: join(__dirname, 'tailwind.config.js'),
// },
autoprefixer: {},
},
}
tailwind.config.js
const { createGlobPatternsForDependencies } = require('#nrwl/react/tailwind');
module.exports = {
purge: createGlobPatternsForDependencies(__dirname),
darkMode: false, // or 'media' or 'class'
theme: {
extend: {},
},
variants: {
extend: {},
},
plugins: [],
};
next.config.js
// eslint-disable-next-line #typescript-eslint/no-var-requires
const withNx = require('#nrwl/next/plugins/with-nx');
/**
* #type {import('#nrwl/next/plugins/with-nx').WithNxOptions}
**/
const nextConfig = {
nx: {
// Set this to true if you would like to to use SVGR
// See: https://github.com/gregberge/svgr
svgr: false,
},
};
module.exports = withNx(nextConfig);
But now if I run the apps, tailwind CSS does not seem to be laded in the app. So what am I doing wrong, and how can fix the issue?

Answer 1

In tailwind.config.js, you should change "purge" into "content" which recommends by the new release version of tailwindcss and also the path should config by starting from the root path. For example: content: ['./apps/blogs/pages/**/*.{js,ts,jsx,tsx}']

YR007 answer should be marked as the correct one, both postcss.config.js and tailwind.config.js should have root references if they are inside a monorepo app, for example:
postcss.config.js
module.exports = {
plugins: {
'tailwindcss/nesting': {},
tailwindcss: { config: './apps/backoffice/tailwind.config.js' },
autoprefixer: {},
},
};
tailwind.config.js
module.exports = {
content: [
'./apps/backoffice/index.html',
'./apps/backoffice/src/**/*.{vue,js,ts,jsx,tsx}',
],
darkMode: 'class',
theme: {
extend: {},
},
plugins: [],
};

**In Nx + Nextjs with tailwind some libs components are missing tailwindcss classes you can configure them like that in tailwind.config.js in Nextjs project **
you can point directly to libary
module.exports = {
content: [
join(__dirname, '**/*.{js,ts,jsx,tsx}'),
join('libs/ui/src/lib/**/*.{js,ts,jsx,tsx}'),
...createGlobPatternsForDependencies(__dirname),
],
}

There is a simple way for it's setup. Make a tailwind.config.js file at root and add this code
module.exports = {
mode: "jit",
purge: [
"./pages/**/*.{js,ts,jsx,tsx}",
],
darkMode: false, // or 'media' or 'class'
theme: {
extend: {},
},
variants: {
extend: {},
},
plugins: [],
};
Create a postcss.config.js file and make this
// postcss.config.js
module.exports = {
plugins: {
tailwindcss: {},
autoprefixer: {},
},
};
Then in your globals.css , simply import tailwind
#import "tailwindcss/base";
#import "tailwindcss/components";
#import "tailwindcss/utilities";
and include this globals.css file in your app.js
