Answer 1

For a project based on the angular2-seed, I needed to:

1. Install underscore package:

   npm install underscore --save
   

2. Add following to typings.json under globalDependencies:

   "underscore": "github:DefinitelyTyped/DefinitelyTyped/underscore",
   

3. Add following under project.config.ts:

   this.SYSTEM_CONFIG_DEV.paths['underscore'] =
       `${this.APP_BASE}node_modules/underscore`;
   this.SYSTEM_BUILDER_CONFIG.packages['underscore'] = {
       main: 'underscore.js',
       defaultExtension: 'js'
   };
   

4. Import "_" in my ts files:

   import * as _ from 'underscore';
