I'm doing the Angular2 5 minute quick start.



About half way through the tutorial now, I have the following files setup correctly:




  • index.html,

  • app.component.ts

  • app/boot.ts

  • package.json

  • tconfig.json



Ran npm start and am getting this error:






Uncaught ReferenceError: require is not defined(anonymous function) @ boot.js:1
angular2-polyfills.js:143
Uncaught TypeError: Cannot read property 'split' of undefinedreadMemberExpression @ system.src.js:1456(anonymous function) @ system.src.js:3224(anonymous function) @ system.src.js:3749complete @ system.src.js:2487run @ angular2-polyfills.js:138zoneBoundFn @ angular2-polyfills.js:111






I found this link about using the es6 shim and I included <script src=node_modules/es6-shim/es6-shim.js></script>.



However I'm still getting the Uncaught ReferenceError: require is not defined error.






app.component.ts



import {Component} from 'angular2/core';

@Component({
selector: 'my-app',
template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }


(app/boot.ts)



import {bootstrap}    from 'angular2/platform/browser'
import {AppComponent} from './app.component'

bootstrap(AppComponent);


index.html



<html>

<head>
<title>Angular 2 QuickStart</title>

<!-- 1. Load libraries -->

<script src=node_modules/rxjs/bundles/Rx.js></script>

<!-- 2. Configure SystemJS -->
<script>

packages: {
app: {

}
});
System.import('app/boot')
.then(null, console.error.bind(console));
</script>

</head>

<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>

OK finally got my 'basic' app to work.



First my problem was that npm start was not compiling my typescript .ts files.



From this post, I found an answer here Cannot find external module 'angular2/angular2' - Angular2 w/ Typescript



I needed to run npm install -g tsd@latest to update my TypeScript definition. Right after that I needed to update the TypeScript Definition (TSD) for Angular2 tsd install angular2.



After this was done I was still getting errors from my boot.js file.



Instead of this import {AppComponent} from './app.component'



I needed to write it like this import {AppComponent} from '../app.component.js'






Now it works! https://github.com/leongaban/angular2quickstart

One annoying problem is that npm start still isn't auto compiling the typescript files, so I still have to manually compile each .ts file by hand tsc app.component.ts --module system
