Building an Angular module that allows for customizable properties: A step-by-step guide

I am in the process of developing an AngularJS module that will simplify interactions with my product's REST API. Since my product is installed on-premise, each user will need to provide their own URL to access the API. Therefore, it is essential that the base URL be customizable.

I have been exploring how to set default headers using $http in order to create a user-friendly API for configuring these properties. However, I have not made much progress so far. My goal is to achieve something similar to this:

In my api.js file:

angular.module('myProduct', [])
  properties.baseUrl = 'someDefault';
  properties.authenticationToken;

  authenticate = function(user, pass) {
    properties.authenticationToken = $http.get(properties.baseUrl + '/login');
  }

In the customer's app.js file:

angular.controller('myController', ['myProduct'], function($myProduct) {
  // Setting the base URL during initialization
  $myProduct.properties.baseUrl = 'customer.com/myProduct';

  // Calling the authenticate function either during initialization or after submitting a login form
  $myProduct.authenticate('username', 'password')
    .then(/* perform additional API calls */);
})

My inquiries include:

  • How can I expose the properties in my module in a user-friendly and easily configurable manner?
  • How can I make the authenticate function accessible within my module so it can be invoked seamlessly from the customer's app.js?

If there are any relevant resources in the Angular documentation that I may have overlooked, please feel free to share them as well.

Answer №1

One method in Angular involves using providers to configure modules.

Also, there are two fiddles available: one demonstrating the use of defaultUrl and another showcasing how to change it from the client side.
