Angular 2 Angular2 provide external data to App before bootstrap Via Dependency Injection
Example
Instead of invoking the Angular’s bootstrap code directly, wrap the bootstrap code into a function and export the function. This function can also accept parameters.
import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";
import { AppModule } from "./src/app";
export function runAngular2App(legacyModel: any) {
platformBrowserDynamic([
{ provide: "legacyModel", useValue: model }
]).bootstrapModule(AppModule)
.then(success => console.log("Ng2 Bootstrap success"))
.catch(err => console.error(err));
}
Then, in any services or components we can inject the “legacy model” and gain access to it.
import { Injectable } from "@angular/core";
@Injectable()
export class MyService {
constructor(@Inject("legacyModel") private legacyModel) {
console.log("Legacy data — ", legacyModel);
}
}
Require the app and then run it.
require(["myAngular2App"], function(app) {
app.runAngular2App(legacyModel); // Input to your APP
});
