The size of the generated file from tailwind build is compact

I've been working with TailwindCSS and have followed the installation process outlined below. However, after completing the steps, I ended up with a tailwind.css file that only contains 369 lines. This seems to be fewer lines than what others have in their tailwind result files, and it's causing me to be unable to use the tailwind styles properly. Could there be something essential that I missed during the installation?

My Installation Process

  1. Starting with CRA-typescript - installed packages without any modifications to tailwindcss.config.js file
npm install -D tailwindcss postcss autoprefixer postcss-cli
npx tailwindcss init
  1. Modified postcss.config.js
module.exports = {
  plugins: [
    require('tailwindcss'),
    require('autoprefixer'),
  ]
}
  1. Edited index.css as follows
@tailwind base;
@tailwind components;
@tailwind utilities;
  1. Created a script and ran it
"scripts": {
  //...
  "build:styles": "postcss src/index.css -o src/tailwind.css", 
}

Any helpful insights are welcome. Thank you.

Recently, Tailwind has embraced the JIT paradigm starting from version 3.0. The main goal was to eliminate the need for large CSS files during the development phase. Instead of purging all unused styles at the end of development, the new approach involves dynamically adding styles while working on the project.

This shift might be confusing for users transitioning from version 2 to version 3. The key step is to configure our tailwind.config.js file to reference our templates with classes.

module.exports = {
  content: ['../templates/core/*.html'],
  theme: {
    extend: {},
  },
  plugins: [],
}

By using the --watch flag in the build process, any new styles added will be automatically included in our main CSS file.

npx tailwindcss -i ./css/input.css -o ./css/style.css --watch

This shift ensures that our CSS files never balloon to unmanageable sizes.

I recently followed the official setup guide for combining Create React App (CRA) with Tailwind CSS, and I was pleasantly surprised by how well it worked. The key difference I noticed was in the configuration files. Here is the setup that worked for me:

postcss.config.js

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
}

tailwind.config.js

module.exports = {
  content: [
    "./src/**/*.{js,jsx,ts,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

Simply running react-scripts start was all it took to get everything up and running smoothly.
