Set up Master CSS in Angular

Guide to setting up Master CSS in your Angular project.

Master CSS Runtime Rendering observes changes in DOM class names at browser runtime, generates corresponding CSS rules, and injects them into the running style sheet.

Fixed style cost

All features work out of the box with ~17KB transfer cost

Fully automatic

Capture any program-generated class names

CSS lifecycle

Generated on-demand and frees memory when not in use

Quick start

Clone the example

Copy-paste the commands to quickly start using the https://angular.rr.rc.css.master.co example.

You can skip all installation steps.

npm create @master/css@rc <project> --example angular-with-runtime-renderingcd <project>npm run dev

Installation

Create a project

If you don't have a Angular project, create one first. It's recommended to refer Angular CLI.

ng new <project>cd <project>

Initialize configuration file

Run the command to create a configuration file master.css.ts.

npm create @master/css@rc

Install Master CSS

Install Master CSS into your project via package managers.

npm i @master/css-runtime@rc

Set up CSS runtime engine

Import master.css.ts into the entry file src/main.ts to enable the runtime engine.

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';import { AppModule } from './app/app.module';import { initCSSRuntime } from '@master/css-runtime'; import config from '../master.css'; initCSSRuntime(config); platformBrowserDynamic().bootstrapModule(AppModule)    .catch(err => console.error(err));

Prevent flash of unstyled content

Add <html hidden> to avoid FOUC caused by the runtime engine not yet injecting CSS rules.

<!doctype html><html lang="en" hidden>

Launch server

Run the development server.

npm run start

Start using Master CSS

Now style your first element using Master CSS syntax!

<h1 class="font:40 font:heavy italic m:12x text:center">Hello World</h1>
