Routing with Angular2

1. Create a default template with the following tutorial http://festintecnologico.blogspot.com.au/2016/05/setup-of-environment-with-vs-code-for.html

2. Add  <base href="/">  before the body tag on index.html

3.Create a file named default.component.ts in the app directory with the following content:
import {Component} from "@angular/core"

@Component({
  selector:'default',
  template:'Welcome to Default Component'
})
export class DefaultComponent{

}


4. Create a file named first-example.component.ts in the app directory with the following content:
import { Component } from '@angular/core';

@Component({
  selector:'myTag',
  template:'This is a test'
})
export class FirstExampleComponent{

}



5. Open main.ts add

import {ROUTER_PROVIDERS} from "@angular/router"

and modify bootstrap to

bootstrap(AppComponent,[ROUTER_PROVIDERS]);

The file should look like:
import { bootstrap }    from '@angular/platform-browser-dynamic';
import { AppComponent } from './app.component';
import {ROUTER_PROVIDERS} from "@angular/router"
bootstrap(AppComponent,[ROUTER_PROVIDERS]);


6. Open app.components.ts

import the following libraries:
import {DefaultComponent} from "./default.component";
import {ROUTER_DIRECTIVES,Routes,Router} from "@angular/router";
import {OnInit} from '@angular/core';

Modify the template to:
template: `
<br />
<h1>
THIS IS AN EXAMPLE</h1>
<br />
<br />
<a default="" href="#" routerlink="">Default</a><br />
<a firstexample="" href="#" routerlink="">First Example</a><br />
<br />
<div>
<br />
<router-outlet></router-outlet><br />
</div>
<br />
`,

Set directives as:
directives:[DefaultComponent, FirstExampleComponent, ROUTER_DIRECTIVES]


Add a Route Decorator as
@Routes([
  {path:'/default', component:DefaultComponent},
  {path:'/firstExample', component:FirstExampleComponent}
  ])


Modify AppComponent class to:

export class AppComponent implements OnInit{
  constructor(private router: Router) {}

  ngOnInit() {
    this.router.navigate(['/default']);
  }
 
}

The file should be like:
import { Component } from '@angular/core';
import {DefaultComponent} from "./default.component";
import {FirstExampleComponent} from "./first-example.component";
import {ROUTER_DIRECTIVES,Routes,Router} from "@angular/router";
import {OnInit} from '@angular/core';



@Component({
  selector: 'my-app',
  template:
`
<br />
<h1>
THIS IS AN EXAMPLE</h1>
<br />
<br />
<a default="" href="#" routerlink="">Default</a><br />
<a firstexample="" href="#" routerlink="">First Example</a><br />
<br />
<div>
<br />
<router-outlet></router-outlet><br />
</div>
<br />
`,


  directives:[DefaultComponent, FirstExampleComponent, ROUTER_DIRECTIVES]
})

@Routes([
  {path:'/default', component:DefaultComponent},
  {path:'/firstExample', component:FirstExampleComponent}
  ])
export class AppComponent implements OnInit{
  constructor(private router: Router) {}

  ngOnInit() {
    this.router.navigate(['/default']);
  }
 
}


7. Finally use Ctrl+Shift+B to compile the code and F5 to run it
