Compiling TypeScript into JavaScript with AngularJS 2.0

Exploring the capabilities of AngularJS 2.0 in my own version of Reddit, I've put together a script called app.ts

///<reference path="typings/angular2/angular2.d.ts" />

import {
    Component,
    View,
    bootstrap,
} from "angular2/angular2";

@Component({
    selector: 'hello world'
})
@View(
    { template: `<div>HelloWorld</div>` })
class HelloWorld {
}
bootstrap(HelloWorld)

However, when trying to compile this into a javascript (js) file using tsc app.ts, I encounter several errors displayed on the command line.

I have installed tsc through npm install -g 'typescript@^1.5.0-beta' and ran npm install as well. The errors point to issues like:

C:\angular2-reddit\typings\angular2\angular2.d.ts(7,22): error TS1005: ')' expec
ted.
C:\angular2-reddit\typings\angular2\angular2.d.ts(14,6): error TS1008: Unexpecte
d token; 'module, class, interface, enum, import or statement' expected.

If anyone has insights on where I might have gone wrong, I would appreciate your help!

Thank you...

Answer №1

In order for the compiler to function correctly, it is essential to provide specific parameters.

> tsc.cmd -m commonjs -t es5 --emitDecoratorMetadata app.ts

Additionally, ensure that you have the appropriate TypeScript definition files from the definitelytyped repository.

> npm install -g tsd@^0.6.0
> tsd install angular2 es6-promise rx rx-lite
