How to render Markdown in Angular
Rendering Markdown in Angular can be accomplished using a library such as ngx-markdown. This library allows you to easily convert Markdown code into HTML, which can then be displayed on your Angular website or application.
To use ngx-markdown, you will first need to install the library via npm by running the command npm install ngx-markdown
. Next, you will need to import the MarkdownModule into your Angular module file.
In the component where you want to display the Markdown content, you will need to import the MarkdownService from the ngx-markdown library. Then, you can use the service’s compile
method to convert your Markdown code into HTML.
For example, you can create a variable in your component to hold the Markdown code, and then use the compile
method to convert it to HTML, which can be displayed on the page using Angular’s built-in interpolation.
import { Component } from '@angular/core';
import { MarkdownService } from 'ngx-markdown';
@Component({
selector: 'app-root',
template: `
<div [innerHTML]="html"></div>
`,
})
export class AppComponent {
markdown = '# Hello, world!';
html: string;
constructor(private markdownService: MarkdownService) {
this.html = this.markdownService.compile(this.markdown);
}
}
In the above example, the markdown variable contains the markdown code and the html variable contains the compiled HTML. The compile
method is used to convert the markdown code to html, which is then displayed on the page using Angular’s built-in interpolation with the [innerHTML]
directive.
Alternatively, you can use the markdown
component provided by the ngx-markdown library. This component can take the markdown code as an input, and it will automatically convert it to HTML and display it on the page.
<markdown [data]="markdown"></markdown>
You can also use the data
input property to bind the markdown code, or you can use the src
input property to load the markdown code from an external file.
<markdown src="path/to/file.md"></markdown>
Furthermore, you can also use the transform
input property to customize the way the markdown code is converted to HTML. For example, you can use it to add custom CSS classes to the generated HTML elements.
<markdown [data]="markdown" [transform]="customTransform"></markdown>
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<markdown [data]="markdown" [transform]="customTransform"></markdown>
`,
})
export class AppComponent {
markdown = '# Hello, world!';
customTransform(html: string): string {
return html.replace('<h1>', '<h1 class="custom-class">');
}
}
In conclusion, rendering Markdown in Angular is a simple process using libraries like ngx-markdown. It provides an easy way to convert markdown
