Upgrading $compile in Angular

In my pursuit to compile HTML content in Angular 4, I have come across options like $compile in Angular 1.

Unfortunately, the suggested alternatives in Angular 2 are now outdated.

If anyone has a better approach, please advise me on the most effective way forward.

Answer №1

When it comes to replacing the $compiler service in Angular, the go-to solution is utilizing the Compiler service. To implement this, you can simply inject it into your code like so:

class MyComponent {
     constructor(compiler: Compiler) {}

If you want a more comprehensive understanding of how the Compiler service can be used for dynamically compiling components, take a look at the insightful article titled Here is what you need to know about dynamic components in Angular.

An illustrative example from the aforementioned article showcases:

ngAfterViewInit() {
  const template = '<span>generated on the fly: {{name}}</span>';

  const tmpCmp = Component({template: template})(class {
  });
  const tmpModule = NgModule({declarations: [tmpCmp]})(class {
  });

  this._compiler.compileModuleAndAllComponentsAsync(tmpModule)
    .then((factories) => {
      const f = factories.componentFactories[0];
      const cmpRef = this.vc.createComponent(tmpCmp);
      cmpRef.instance.name = 'dynamic';
    })
}
