Installation

To install this library, run:

$ npm install angular-prism --save

Usage

Include the required prism theme CSS in your index.html or plug into your build System

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/prism/1.6.0/themes/prism-okaidia.min.css"/>

Configure your System.config

System.config({
  defaultJSExtensions: true,
  map: {
    "angular2": "node_modules/angular2",
    "rxjs": "node_modules/rxjs",
    ...
    "prismjs": "node_modules/prismjs"
    "angular-prism" : "node_modules/angular-prism/dist"
  },
  packages: {        
    'app': {
      main : './main.ts',
      defaultJSExtensions : 'ts'
    },
    'prismjs' : {
      defaultExtension : 'js'
    },
    'angular-prism' : {
      main : './angular-prism.js',
      defaultExtension : 'js'
    }
  }
});

and then from your Angular AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

/* Import prism core */
import 'prismjs/prism';

/* Import the language you need to highlight */
import 'prismjs/components/prism-typescript';

import { PrismComponent } from 'angular-prism';

@NgModule({
  declarations: [
    AppComponent,
    PrismComponent
  ],
  imports: [
    BrowserModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

and in your component which displays code block

@Component({
  selector: 'my-app',
  template: `
    <div>
      <prism-block [code]="cssCode" [language]="'css'"></prism-block>
    </div>
  `,
})
export class MyComponent {
  cssCode : string;

  constructor() {
    this.cssCode = `p {
                      color:red;
                    }`;

    }
}
