Quick Guide

app.module.ts

This library has dependency on HttpClientModule. It should be always provided in your application.

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

import { NgxMdModule } from 'ngx-md';
import { HttpClientModule } from '@angular/common'
import { AppComponent } from '../src/app.component';

@NgModule({
  imports: [
    BrowserModule,
    HttpClientModule,
    NgxMdModule.forRoot(),
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})

index.html

If you want syntax highlighting you need to import the prism css file.

Alternative 1: Import from cdn

<head>
    <meta charset="utf-8">
    <base href="https://github.com/dimpu/ngx-md/blob/main/">

    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="icon" type="image/x-icon" href="https://github.com/dimpu/ngx-md/blob/main/favicon.ico">
    <link href="https://cdnjs.cloudflare.com/ajax/libs/prism/1.6.0/themes/prism.min.css" rel="stylesheet" />
  </head>

Alternative 2: Download the css file (or copy it from node_modules/prismjs/themes/, place it somewhere in your src folder and import

<link href="https://github.com/dimpu/ngx-md/blob/main/css/prism.min.css" rel="stylesheet" />

Alternative 3: Include the prism css file in your sass style file

@import 'prismjs/themes/prism.css';

To support sytnax helight for other langugage you need to include

// import 'prismjs/prism';
import 'prismjs/components/prism-c';
import 'prismjs/components/prism-cpp';
import 'prismjs/components/prism-csharp';
import 'prismjs/components/prism-css';
import 'prismjs/components/prism-diff';
import 'prismjs/components/prism-java';
import 'prismjs/components/prism-javascript';
import 'prismjs/components/prism-perl';
...
...
...

app.component.html

<div Markdown>
    ### your markdown code
</div>

<!-- or use angular component -->

<ngx-md>
    ### your markdown code
</ngx-md>

<!-- to load from remote URL -->

<div NgxMd [path]="'/path/to/readme.md'" (error)="errorHandler($event)" (loaded)="loadedHandler($event)" (rendered)="renderedHandler($event)"></div>

<!-- load remote source code with auto syntax highlighting -->

<ngx-md [path]="'/path/to/code.cpp'"></ngx-md>

<ngx-md [path]="'/path/to/code.java'"></ngx-md>

<!-- load remote source code from url stored in variable
(see additional details about variable binding in the next section) -->

<ngx-md [path]="urlVariable"></ngx-md>

<ngx-md [path]="urlVariable" (loaded)="onLoad($event)" (error)="onError($event)"></ngx-md>

Variable binding

Now, with >1.4.x you can bind a variable to the markdown component. To do so:

@Component({
    selector: 'app-root',
    template: `
    <textarea [(ngModel)]="textData"></textarea>
    <ngx-md [data]="textData"></ngx-md>
    `,
})
export class MyComp {
  public textData = `## Markdown content data`;
}

Marked customization

Marked can be customized/extended by accessing the renderer from the MarkdownService:

import { NgxMdService } from 'ngx-md';
@Component({
    selector='my-comp',
    template: `
    <ngx-md>
     > Block
     > quote
     > here
    </ngx-md>
    `,
})
export class MyComp {
  constructor(private _markdown: NgxMdService) {}

  ngOnInit() {
    this._markdown.renderer.blockquote = (quote: string) => {
      return `<blockquote class="king-quote">${quote}</blockquote>`;
    }
  }

See marked documentation for all renderer extension points.

Example

You can find a working example inside the demo directory.
