In this module, we will build the AJAX API for our course project using the XMLHttpRequest object. Starting with a basic front-end setup, we will create GET, POST, PUT, and DELETE requests, integrating them into our project. We will address CORS issues by implementing custom middleware and using third-party modules like "cors". Additionally, we will focus on modularizing our AJAX functionality, making our code more readable and maintainable for future development.

In this module, we will upgrade our AJAX API by transitioning from the XMLHttpRequest object to the modern Fetch API. We will rewrite our GET, POST, PUT, and DELETE requests using Fetch, leveraging Promises to handle asynchronous operations more effectively. This refactoring will not only modernize our code but also enhance its efficiency and readability, ensuring a more robust and maintainable codebase.

In this module, we will incorporate Axios, a popular third-party library, into our project for making AJAX requests. We will start by installing and configuring Axios, then proceed to implement our CRUD operations using this library. By using Axios, we will simplify our code and improve data handling through its intuitive response objects, making our AJAX API more efficient and easier to work with.

In this module, we will bring together all the components of our course project. We will develop the final front-end using HTML, CSS, and JavaScript, creating a cohesive and functional user interface. By connecting this front-end with our back-end server through AJAX APIs, we will enable dynamic interactions and real-time updates, providing a seamless user experience. This final integration will showcase the culmination of our skills in building a full-stack web application.

In this concluding module, we will review the key concepts and skills we've acquired throughout the course. We'll reflect on how these can be applied to future projects and discuss potential improvements. Finally, we'll celebrate the completion of this comprehensive journey, recognizing the readiness to tackle new web development challenges with confidence and expertise.
