Top method for isolating AngularJs controller code

I have a question regarding organizing bulk code in an AngularJs controller. I currently have a controller named userDashboard.js with numerous methods for making API calls to retrieve data, such as:

1) Charts - Chart 1, Chart 2, Chart 3, etc.

2) Tables - Table 1, Table 2, etc.

3) Sections - 1, 2, 3, etc.

I would like to create separate JavaScript files for each functionality within the same controller to improve code readability and maintainability. How can I accomplish this?

Would it work if I use the same controller name in other files, like:

controller1.js

'use strict';
angular.module('onepgr')
  .controller('userDashboard',
  function ($scope, $routeParams, MyAppService, Excel, $timeout) {
   //API
   //Chart
  });

controller2.js

'use strict';
angular.module('onepgr')
  .controller('userDashboard',
  function ($scope, $routeParams, MyAppService, Excel, $timeout) {
    //Table function
    //API
  });

Answer №1

Instead of copying controllers, develop new ones. To handle shared functionalities, generate a service/factory that can be accessed by all controllers and store common business operations there.

Answer №2

Personal preference plays a significant role in this decision. Take a look at the insight provided by Sajan Mullappally.

Additionally, johnpapa has developed a helpful guideline that has been approved by the Angular team. https://github.com/johnpapa/angular-styleguide

Evaluate whether this aligns with your preferences and those of your team members. Ultimately, you are the ones who will be interacting with the code on a daily basis, so it is important for you to determine what works best for your specific situation.
