Issue: Module "expose?Zone!zone.js" could not be located

Just started experimenting with Angular 2 and encountering an issue when importing zone.js as a global variable:

https://i.stack.imgur.com/gUFGn.png

List of my packages along with their versions:

"dependencies": {
    "angular2": "2.0.0-beta.3",
    "es6-promise": "3.0.2",
    "es6-shim": "0.33.13",
    "expose-loader": "^0.7.1",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.0",
    "zone.js": "0.5.11"
}

Included zone.js in my index.ts using import 'expose?Zone!zone.js';.

Furthermore, the index.ts serves as the main entry point in the webpack.config.js file.

Seeking guidance on the correct method to import zone.js by exposing it as a global variable (utilizing expose-loader due to WebPack usage).

Answer №1

Zone.js plays a crucial role as a dependency of Angular 2 polyfills, as highlighted by Eric Martinez. Current resources on integrating Angular 2 with Webpack may be limited, but setting it up is actually quite straightforward.

To begin, in your main entry file or a separate one for vendor code, ensure the following imports are included:

// bundle.ts

import 'es6-shim';
import 'angular2/bundles/angular2-polyfills';
import 'rxjs';

These imports suffice for basic functionality. However, if you wish to segregate vendor code into a distinct chunk using Webpack's CommonsChunkPlugin, make sure to import other Angular 2 files needed later in your application:

// vendor.ts

import 'es6-shim';
import 'angular2/bundles/angular2-polyfills';
import 'angular2/platform/browser';
import 'angular2/core';
import 'angular2/router';
import 'rxjs';
