In Ember.js, you can declare a constants file by creating a new file inside the app/utils directory (or any other directory you prefer). Inside this file, you can export the constants like below:

1
2
3
4
5
6
7
// app/utils/constants.js

export default {
  API_URL: 'https://api.example.com',
  MAX_RESULTS: 10,
  DEFAULT_COLOR: 'blue'
};


You can then import and use these constants in your Ember components, services, routes, etc. as needed. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
// app/components/my-component.js

import Constants from '../utils/constants';

export default Ember.Component.extend({
  init() {
    this._super(...arguments);

    console.log(Constants.API_URL); // Outputs: 'https://api.example.com'
    console.log(Constants.MAX_RESULTS); // Outputs: 10
    console.log(Constants.DEFAULT_COLOR); // Outputs: 'blue'
  }
});


By using a constants file, you can maintain all the constants in one place and easily reference them throughout your application.
