Even if the Günter's answer is great, I wasn't able to resist to create a little plunkr describing how to use Marked into a component: https://plnkr.co/edit/0oSeaIyMWoq5fAKKlJLA?p=preview.

Here are the details:

• Marked configuration the HTML file

• The component that uses Marked

  import { Component, Input } from 'angular2/core';
  import marked from 'marked';
  
  @Component({
    selector: 'markdown', 
    template: `
      
  
    `
  })
  export class MarkdownComponent {
    @Input('data')
    data:string;
  
    ngOnChanges() { 
      this.convertedData = marked(this.data);
    }
  }
  

• The component that uses the previous Markdown component

  import { Component } from 'angular2/core';
  import { MarkdownComponent } from './markdown';
  
  @Component({
    selector: 'my-app', 
    template: `
      
  
        
      
    `,
    directives: [ MarkdownComponent ]
  })
  export class AppComponent {
    constructor() {
      this.markdown = 'Hello';
  
      setTimeout(() => {
        this.markdown = `
  # Title
  
  Some __test__
  `;
      }, 1000);
    }
  }
