Angular Code Builder

Write <code><code> in Angular templates in a declarartive way without caring about escaping special characters.

Usually in Angular templates you have to escape braces like { to {{'{'}} and } to {{'}'}}, otherwise the Angular compiler throws an error:

Unexpected character "EOF" (Do you have an unescaped "{" in your template? Use "{{ '{' }}") to escape it.) 

The Angular Code Builder does this "annoying" escaping for you, at build time.

Usage

ng add angular-code-builder

Then you should be able to write code parts directly in your template file:

<pre><code>
function sharksAreComing() {
  console.log('Shark is coming..');
}
</code><pre>

Without Angular Code Builder you would have to write:

<pre><code>
function sharksAreComing() {{'{'}}
  console.log('Shark is coming..');
{{'}'}}
</code><pre>

How does it work?

We are using a Angular Schematics to configure a custom webpack loader for html in which we search for <code> elements and do the escaping automatically.

For the custom webpack configuration we use the custom webpack builder: https://www.npmjs.com/package/@angular-builders/custom-webpack

Configuration

When you want to use a custom Angular component that wraps your code and for example does use prism to highlight your code you can configure the element tag on which we match in angular-code-builder/escapeBraces.js:

default:
const MATCH_BLOG_CODES = /(<code(.*?)>)([\s\S]*?)(<\/code>)/g;

change it if necessary;
const MATCH_BLOG_CODES = /(<blog-code(.*?)>)([\s\S]*?)(<\/blog-code>)/g;
