Code your Angular website faster with Stylify CSS

Code your Angular website faster with Stylify CSS



Style your Angular app quickly and easily with Stylify CSS. Split CSS for large pages or create one bundle for a whole app and get extremely small CSS.

Introduction

Stylify is a library that uses CSS-like selectors to generate optimized utility-first CSS based on what you write.
  • ✅ CSS-like selectors
  • ✅ No framework to study
  • ✅ Less time spent in docs
  • ✅ Mangled & Extremely small CSS
  • ✅ No CSS purge needed
  • ✅ Components, Variables, Custom selectors
  • ✅ It can generate multiple CSS bundles

Also we have a page about what problems Stylify CSS solves and why you should give it a try!

Installation

First, install the @stylify/bundler package using NPM or Yarn:

npm i -D @stylify/bundler
yarn add -D @stylify/bundler

Also for the watch mode, we need to run two parallel tasks. This can be solved using concurrently:

yarn add -D concurrently
npm i concurrently

Next, create a file, for example stylify.js:

const { Bundler } = require('@stylify/bundler');

const isDev = process.argv[process.argv.length - 1] === '--w';
const bundler = new Bundler({
  watchFiles: isDev,
  // Optional
  compiler: {
    mangleSelectors: !isDev,
    // https://stylifycss.com/docs/stylify/compiler#variables
    variables: {},
    // https://stylifycss.com/docs/stylify/compiler#macros
    macros: {},
    // https://stylifycss.com/docs/stylify/compiler#components
    components: {},
    // ...
  },
});

// This bundles all CSS into one file
// You can configure the Bundler to bundle CSS for each page separately
// See bundler link below
bundler.bundle([
    {
        files: ['./src/**/*.html', './src/**/*.ts'],
        outputFile: './src/styles.css',
    },

    // You can also split CSS for each component
    // You can map files within the components using content comment option
    // https://stylifycss.com/docs/bundler#files-content-option
    // Stylify takes that option and searches for defined files. If defined file
    // also has an option, id check also those files and so long.
    // This way it maps all files and all dependencies.
    /*
    {
        files: ['./src/app/app.component.*'],
        outputFile: './src/app/app.component.css',
    },
    */
]);

If you don't define multiple bundles, everything will be bundled into the styles.css. If you define multiple bundles, don't forget to add paths to those generated files into Angular components.

The last step is to add scripts into the package.json:

"scripts": {
    "dev": "concurrently 'yarn stylify.dev' 'ng serve -c development'",
    "prod": "yarn stylify.build & ng serve",
    "stylify.build": "node stylify.js",
    "stylify.dev": "node stylify.js --w"
}

In production, you will get optimized CSS and mangled HTML:

<h1 class="font-size:24px color:#dd0031 font-family:arial">
Hello World!
</h1>
.a{font-size:24px}
.b{color:#dd0031}
.c{font-family:arial}
