Loading Libraries from CDN

If we want to use React from a shared CDN instead of through SystemJS, we can build our bundle with react as and react-dom as excludes:

  jspm bundle test.js - react - react-dom app-bundle.js -m

Then in jspm.browser.js, in order to provide the react and react-dom to the CDN versions, we need to add custom paths configs:

SystemJS.config({
  baseURL: "/",
  production: true,
  paths: {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*",
    "jspm-react-component/": "src/",
    "npm:[email protected]": "https://fb.me/react-15.1.0.min.js",
    "npm:[email protected]": "https://fb.me/react-dom-15.1.0.min.js"
  }
});

We use CloudFlare over Facebook's CDN here because Facebook's CDN doesn't set the Access-Control-Allow-Origin: '*' header which is needed for SystemJS support.
