What is the best way to set up a hook that runs following every XHR request?

My scenario:
I am utilizing Angular in combination with a Django backend. The Django framework offers an useful built-in feature called messages, which enables displaying one-time messages to users, such as "Your account has been successfully activated!". My goal is to leverage AJAX for showing these messages - by making requests after each XHR from the client, as detailed in this article.

Any suggestions on how to create this kind of hook?

Answer №1

Utilizing the httpInterceptor is recommended for executing specific tasks before or after every $http request.

To learn more about setting up an http interceptor, check out this informative post.

The key is to create a factory with the desired functionality.

module.factory('myCustomInterceptor', ['$q', 'someAsyncService', function($q, someAsyncService) {
    var requestInterceptor = {
        request: function(config) {
                   //insert your custom logic here
        }
    };

    return requestInterceptor;
}]);

Lastly, don't forget to add it to the list of http interceptors.

module.config(['$httpProvider', function($httpProvider) {
    $httpProvider.interceptors.push('myCustomInterceptor');
}]);
