One thing that I've noticed is that the AngularJS (*.js) files I've come across typically only have one module, and the module name doesn't always match the file name.
I'm curious to know if it's possible to include multiple modules in a single AngularJS file.
Additionally, how does the server determine the correct module name when a function call is made on a webpage? Does it search through each file in the directory in a brute force manner?
It is possible to include multiple modules in a single file, although it may not be considered best practice. Angular is able to determine which module to load by registering each individual module with Angular.
angular.module('myModule', [])
This allows Angular to avoid having to search for modules based on naming conventions.
When referencing a module name in your HTML, you can use ng-app="yourModule" on an HTML element. It is perfectly fine to have multiple modules in a single file. In fact, this is what the minification and obfuscation processes do to create production-ready code: Combine all of your JavaScript code into one file.
My recommendation is:
Absolutely, it is perfectly acceptable to include multiple modules in a single file. However, it is important to ensure that all modules are registered before the application is bootstrapped to avoid encountering a dependency error. For further information on this topic, you can refer to the section on dependency injection.
One common approach is to have a separate file for each module declaration. For more details, check out the resource available at: Angular Best Practices
When working with Angular, you typically register each module using angular.module. From there, you can proceed to define your services, controllers, and more within the context of the specific module.
angular.module("myApp", []); // Register the module
angular.module("myApp").service("myService", function(){}); // Define a service within the myApp module
