Ember inject POJO

foo.js

// app/initializers/foo.js

var POJO = {
  bar: 'this is your POJO'
  // whatever you need here
  // this can also be import from another file...
};

export function initialize(container, application) {
  application.register('pojo:main', POJO, { instantiate: false, singleton: true });
  application.inject('route', 'foo', 'pojo:main');
  // application.inject('component', 'foo', 'pojo:main');
  // inject whereever you need it...
  
  // then in your routes (or whereever) do:
  // `this.foo` and you should have your POJO
}
