Angular2 - Dynamically load component from module

Question

in my angular app I have the following:

export class MyComponent {
    subcompPath = \"path-to-subcomp#SubcompClassName\";
    @ViewChild(\"placeholder\", {          


        

Answer 1

Update:

If you want to use it together with aot compilation you should manually provide Compiler like

export function createJitCompiler () {
   return new JitCompilerFactory([{useDebug: false, useJit: true}]).createCompiler();
}
...
providers: [
  { provide: Compiler, useFactory: createJitCompiler}
],

Example

It might help you:

this.compiler.compileModuleAndAllComponentsAsync(DynamicModule)
      .then(({moduleFactory, componentFactories}) => {
        const compFactory = componentFactories
           .find(x => x.componentType === DynamicComponent);
        const cmpRef = this.placeholderRef.createComponent(compFactory, 0);

Answer 2

Based on yurzui's answer I've come to the following code:

export class MyComponent {
    subcompPath = "path-to-subcompMODULE#SubcompClassName";
    @ViewChild("placeholder", { read: ViewComponentRef }) placeholderRef: ViewComponentRef;

    /* Constructor where Compiler, ComponentFactoryResolver are injected */

    loadSubcomponent() {
        let [modulePath, componentName] = this.subcompPath.split("#");
        (<any>window).System.import(modulePath)
            .then((module: any) => module["default"])  // Or pass the module class name too
            .then((type: any) => {
                return this._compiler.compileModuleAndAllComponentsAsync(type)
            })
            .then((moduleWithFactories: ModuleWithComponentFactories<any>) => {
                const factory = moduleWithFactories.componentFactories.find(x => x.componentType.name === componentName); // Crucial: componentType.name, not componentType!!
                let componentRef = this.placeholderRef.createComponent(factory, 0);
            });
    }
}
