Do you want to build faster, more interactive web applications that communicate with servers without repeatedly reloading the page?
The AJAX Next Level: Authentication, Servers & Real-World Projects program provides a practical introduction to asynchronous requests, APIs, authentication, server configuration, PHP, Node.js, Express, and full-stack application development.
You can start learning free by opening an individual course and checking whether selected preview lessons are available before choosing full enrollment.
What Is the AJAX Next Level Program?
This beginner-friendly program includes three courses that progress from AJAX fundamentals to authentication, cross-origin requests, REST APIs, and backend development.
It is designed for learners with basic knowledge of HTML, CSS, and JavaScript. Previous AJAX experience is not required.
The complete learning path takes approximately four weeks when studying around ten hours per week.
What Will You Learn?
Throughout the program, you will learn how to:
- Understand the role of AJAX in modern web development
- Send asynchronous requests with XMLHttpRequest
- Use the modern Fetch API
- Retrieve and display JSON data
- Connect applications to internal and third-party APIs
- Work with PHP and Node.js servers
- Understand the Same-Origin Policy and CORS
- Add Basic Authentication to AJAX requests
- Configure Apache servers and
.htaccessfiles - Create RESTful API endpoints with Express
- Test backend routes using Postman
- Use middleware, modules, and NPM
- Build responsive, data-driven web applications
These skills can help you connect front-end interfaces with backend services and create smoother user experiences.
Courses Included in the Program
1. Introduction to AJAX and Mini-Projects
Begin with AJAX fundamentals and understand the difference between synchronous and asynchronous requests.
You will use XMLHttpRequest and Fetch API to retrieve, process, and display information from servers and external APIs through practical mini-projects.
2. AJAX Authentication and Cross-Origin Requests
Learn how AJAX applications handle authentication and cross-origin communication.
Topics include Apache configuration, .htaccess, Basic Authentication, Base64 credential handling, CORS, the Same-Origin Policy, and upgrading older XMLHttpRequest code to Fetch API.
3. Advanced AJAX Techniques and Final Projects
Move into backend application development with Node.js, Express, NPM, middleware, modules, and RESTful services.
You will create API endpoints, test routes with Postman, connect front-end and backend components, and build a complete server-based application.
