npm install -g jspm@betajspm initjspm install angular2 reflect-metadata zone.js es6-shimThis will create a jspm_packages folder, and a config.js file.
Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate
The single hardest part of front-end development at scale is making changes to code and understanding all of the visual and behavioral effects that will occur as a result.
When you build a component, tests should be written that expose each state a component can be in. This test should generate a static html file and a corresponding image for every discrete state a component can be in.

This year marks the first year that we are doing full scale rendering of our SPA application on our mobile.walmart.com Node.js tier, which has provided a number of challenges that are very different from the mostly IO-bound load of our prior #nodebf.
The infrastructure outlined for last year is the same but our Home, Item and a few other pages are prerendered on the server using fruit-loops and hula-hoop to execute an optimized version of our client-side JavaScript and provide a SEO and first-load friendly version of the site.
To support the additional CPU load concerns as peak, which we hope will be unfounded or mitigated by our work, we have also taken a variety of steps to increase cache lifetimes of the pages that are being served in this manner. In order of their impact:

| beforeEach(module('monModuleATester')); | |
| // Inject ce que tu as besoin | |
| // inject() est obligatoire, c'est direct ngMOck | |
| beforeEach(inject(function ($rootScope, $injector) { |
