Collaborative AngularJS $http intercept strategies

Question

Collaborative AngularJS $http intercept strategies

I'm curious whether Angular.js $http interceptors are shared across the entire application. What if I have a module called myDependentApp, which is used by multiple apps? This module has some interceptors configured to manage $http requests/responses. I include this module by declaring it in the application bootstrap:

angular.module('myApp', ['myDependentApp']);

Then, I have an application template:

<html ng-app="myApp">

Will myDependentApp's interceptors be active in myApp?

Thanks for the assistance.

Answer №1

A positive response is confirmed, as I have personally tested it in this scenario:

var dependentApp = angular.module('dependency',[]).config(['$httpProvider', function($httpProvider) {
    $httpProvider.interceptors.push(function ($q) {
        return {
            'request': function (config) {
                console.log('request intercept');
            },

                'response': function (response) {
                console.log('response intercept');
            }
        };
    });
}]);

var app = angular.module('myapp', ['dependency']);
app.controller('mycontroller', ['$scope', '$http', function ($scope, $http) {
    $http.get('http://www.google.com');
}]);

Upon observation, the intercepted request was successfully executed. You can view the fiddle demonstration here: http://jsfiddle.net/6dbgo6pt/1/

Answer №2

A positive response is affirmed.

Sourced directly from the documentation

Angular services have these characteristics:

They are lazily created – Angular only creates a service when it is needed by an application component.

Singletons – Each component that relies on a service receives a reference to the one instance produced by the service factory.

$http is an example of such a service that is formed utilizing the provider recipe.

This implies that every module in your application will utilize the same $http service and any modules adding interceptors will share them with other modules because, once again, the $http service operates as a singleton similar to any other angular or custom-built service made using .service, .factory, or .provider.

$http Interceptors:

When it comes to implementing global error handling, authentication, or any type of pre-processing of requests or postprocessing of responses, the ability to intercept requests and responses is crucial. This allows for synchronous and asynchronous pre-processing using promise APIs.

The interceptors act as service factories that can be registered with the $httpProvider by adding them to the $httpProvider.interceptors array. These factories are called and provide dependencies (if specified) in order to return the interceptor.

$httpProvider:

Utilize $httpProvider to modify the default behavior of the $http service.
