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.
globalVarName
