Config / Example

---

When you are using SystemJs you need to load angular2-set-class-in-view dependency

'angular2-set-class-in-view': {
        main: './main.js',
        defaultExtension: 'js'
      }

and map 'angular2-set-class-in-view to 'node_modules/angular2-set-class-in-view'.

Your systemjs.config.js could look like:

(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      'rxjs':                       'npm:rxjs',
      'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
      'angular2-set-class-in-view': 'npm:angular2-set-class-in-view'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      },
      'angular2-in-memory-web-api': {
        main: './index.js',
        defaultExtension: 'js'
      },
      'angular2-set-class-in-view': {
        main: './main.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);
