Angular2 - error in long-stack-trace-zone.js at line 106: Zone variable is not defined

Currently, I am utilizing the Angular2 starter with webpackjs AMD. While there are no build errors showing up, I encounter some issues when browsing (using npm server), resulting in the following errors:

What aspects might I be overlooking in my build configuration? What other factors should I review to ensure everything runs smoothly?

Thank you in advance.

//error one

In long-stack-trace-zone.js:106, an Uncaught ReferenceError occurs where Zone seems to be undefined. This issue is preventing specific functionalities from working as expected. The trace further indicates dependencies failing to load properly, impacting the application's performance.

//error two

The use of class decorators demands reflection metadata shim for proper integration. Missing out on this crucial element leads to potential failures and inconsistencies in functionality across the application. It is essential to address this requirement to maintain stability.

// Polyfills

import 'es6-promise';
import 'zone.js/dist/long-stack-trace-zone';
import 'reflect-metadata';

Answer №1

To ensure proper functionality, it is crucial that you include the zone module in your polyfills. Furthermore, there is no need for the es6-promise module when using es6-shim, as it already contains similar functionality.

import 'es6-shim';
import 'zone.js/dist/zone'; // Don't forget this one
import 'zone.js/dist/long-stack-trace-zone';
import 'reflect-metadata';

Remember to upgrade to beta.12 and zone.js 0.6.6 as these versions address several bugs present in earlier releases related to the zone functionality.
