Index.html works as an App Shell, which render meanful pixel onto the screen. And our module will be rendered when the data binding is ready.
Create first Module:
This module will bootstrap our application, normally this only happen once. This is the main entry point of the whole application.
import {Component, NgModule} from "@angular/core";
import {platformBrowserDynamic} from "@angular/platform-browser-dynamic";
import {BrowserModule} from "@angular/platform-browser";
@Component({
selector: ‘app‘,
template: `<h1>Hello Angular 2</h1>`
})
export class App{
}
/*
* Declare the NgModule
* */
@NgModule({
declarations: [App], // tell which component will be include into this module
imports: [BrowserModule], // if building web app, we need to use BrowserModule, native mobile app use other module
bootstrap: [App] // App component will be the entry point of the whole application
})
export class AppModule{
}
// Bootstrap the AppModule
platformBrowserDynamic().bootstrapModule(AppModule);
Last insert out App into html:
<div class="l-course-content card card-strong lesson-1">
<app></app>
</div>
