How to use templateUrl?

Description

I'm going with the following file structure:

./src
   app/
      app.component.html
      app.component.ts
   index.html
   index.ts

But when I want to use templateUrl: 'app.component.html' in my app.component.ts I get the following Error Message & Stack Trace (see below).

I succeeded to fix the problem by writing the full relative path: ./app/app.component.html but this is bad and when my app will grow (and it will grow pretty fast), moving components in subfolders will be a real pain.

In Angular Style guide, they suggest just to use templatename.html instead of ./relativepath/templatename.html but this does not work for me. Have you tried? Is it related to Webpack? Should I switch to SystemJS instead?

By the way, I suggest your generator to use templateUrl in one of your samples (todoMVC for example?) as a best practice 👍

Hi, thanks for following the issue template @wembernard
External template with Angular 2 will be part of the next release, the code is already on master. Meanwhile here are the steps you need to go through with angular2/webpack:

  • template = require('relative/path/to/template.html')

  • you also need to add moduleId: __moduleName in @Component({...})

  • at last, you need to install and set up the Webpack html loader

    • In conf/webpack-*.conf.js you have to add the following into module.loaders array
    {
  test: /.html$/,
    loaders: [
      'html'
    ]
}
    • npm install html-loader --save-dev

All this will be in next release in few days 😉
