Ember Patch Config

Patch Ember CLI 2.x app configuration at runtime.

What is it for?

Well, sometimes you just want to change ember's config (app/config/environment.js) before everything is loaded, or even extract it programmatically from Local Storage or a Cookie.

Ok, how?

First you need to import EmberApp from a different location:

// ember-cli-build.js

const EmberApp = require('ember-patch-config/ember-app');

module.exports = function (defaults) {
	const app = new EmberApp(defaults, {
        // ...
    }
}

Then, add an inline script in app/index.html (before the app & vendor scripts):

<!-- app/index.html -->
<!DOCTYPE html>
{{content-for 'rev-header'}}
<html>
  <!-- ... -->
  <body>
    <!-- ... -->
    <script>
        window.configToPatch = {
            property1: 'value1',
            property2: 'value2',
            property3: {
                someKey: 'someValue'
            },
            property4: localStorage.getItem('property4')
        };
    </script>
    <!-- ... -->
  </body>
</html>

The content of window.configToPatch will be DEEPLY MERGED into the module <your-app-name>/config/environment.js at runtime, before the app is initialized (even before initializers).

Options

Options can be passed within the ember-patch-config node of EmberApp options object.
