About the Advanced AJAX Online Course
This Advanced AJAX course is designed to elevate your skills in creating dynamic, interactive web applications without page refreshes. You will start with foundational AJAX concepts and progress to advanced topics like Basic Authentication, CORS, and server communication. Learn how to send authentication data using the XHR object and Fetch API, handle user inputs, convert them to JSON, and send them to the server. You'll also gain expertise in retrieving XML, JSON, and text data from servers, dynamically updating pages with JavaScript, and working with RESTful AJAX APIs. By the end of the course, you will be able to build fully functional sites that perform CRUD operations, interact with servers, and apply AJAX effectively in real-world applications.
Key Benefits
- You will learn to resolve CORS errors and configure the server to run on a different port from your front-end code.
- Additionally, you will gain hands-on experience in performing CRUD operations, with all AJAX code written in modular form, ensuring RESTful compliance throughout the process.
Target Audience
This course is designed for individuals aspiring to become experts in front-end development, equipping them with the skills and confidence to navigate the entire process. It is ideal for those looking to build their own frameworks or better understand the source code of established frameworks and libraries.
The course is also suited for those who wish to dive deeper into JavaScript-heavy frameworks and gain a comprehensive understanding of the front-end web development workflow. Targeted at beginners to advanced programmers, it is particularly beneficial for intermediates who are familiar with the basics and have some experience with AJAX but wish to explore its inner workings in greater detail.
Learning Objectives
- Master the process of sending authentication information using both XHR and Fetch.
- Gain expertise in setting up various server environments, including Apache, PHP, and Node servers.
- Understand the principles of RESTful APIs and learn how to configure a server to manage and store your data.
- Learn how to retrieve and manipulate JSON and text data from server responses.
- Explore how to utilize the DOMContentLoaded event to trigger AJAX requests.
- Develop the skills to access and process XML data received from server responses.
