How to communicate data between controllers in ember.js?

There are several ways to communicate data between controllers in Ember.js:

1. Using services: Services in Ember.js act as a global store for data that can be accessed by multiple controllers. You can define a service with the data you want to share and then inject it into the controllers that need access to that data.
2. Using the Ember Data store: If you are working with Ember Data, you can use the store to retrieve and share data between controllers. The store acts as a centralized repository for all the models in your application.
3. Using queryParams: You can use queryParams in your routes to pass data between controllers. QueryParams allow you to define parameters in the URL that can be used to filter and share data between controllers.
4. Using the model hook in routes: If you are using nested routes in your application, you can use the model hook in the parent route to load and share data between controllers.

Overall, the best approach to communicate data between controllers in Ember.js depends on the specific requirements of your application. You may need to combine multiple techniques or use a custom solution to meet your needs.
