Common Ajax request libraries include the following:

  • 1. Fetch API. The Fetch API is a modern replacement for XMLHttpRequest for retrieving resources from the server. It has a more powerful feature set and more meaningful naming. Based on its syntax and structure, Fetch is not only flexible but also easy to use. Fetch follows a request-response approach, that is, Fetch makes a request and returns a promise that resolves to a Response object. Fetch has support for all modern web browsers.

  • 2. jQuery’s $.ajax() method. This is a very common method, which can make asynchronous data requests and return data in JSON format.

  • 3. Axios. Axios is a Promise-based HTTP client that can be used in the browser and node.js. It can perform asynchronous operations, supports Promise API, can handle GET, POST and other requests, and also supports cancellation of requests, conversion of requests and response data, etc.

  • 4. XMLHttpRequest. This is the earliest implementation of AJAX, which creates an XMLHttpRequest object on the front end to send an asynchronous HTTP request to obtain server-side data.
