![]() Similar to Fetch, it uses Promise to handle responses asynchronously. AxiosĪxios is one of the most popular libraries used to make HTTP requests and it works for both front-end and back-end Javascript. If you want to use Fetch for Node.js, you can use an external module like node-fetch. It is implemented in Node v17.5.0 onwards but it is still in an experimental phase. It will only throw an error when it is network-related.Īlthough Fetch is Javascript, it might not be available for some versions of Node.js. For example, if you already get the data using response.json(), you can’t use response.text() for the same request.Īnother thing to take note of when using Fetch is that it won’t reject HTTP response errors from the server like 4xx and 5xx. However, the response can only be accessed using one of the methods. It can be as short as the example below to make a default GET request :įor other types of requests, you can refer to this POST request example.īesides JSON, the response can be resolved into various types of formats using other methods like text(), formData(), blob(), and arrayBuffer(). Making a request using Fetch is simple as the path to the request is the only mandatory field. HTTP requests made using the fetch() method will return a Promise that resolves to a Response object. You can use the global fetch() method to make a request instead, making the code much shorter and readable.įetch is a Promised-based API. Unlike XMLHttpRequest, you don’t need to create a new instance of the Request object to make an HTTP request to the server. It reduces the data transfer between client. The Fetch API is also similar to XMLHttpRequest but with a cleaner syntax. Http client programming enables the application to connect and fetch data from http server through JavaScript. ![]() It implements the Promise interface, hence the HTTP request is asynchronous and allows multiple callbacks. The $.ajax method and the shorthand methods return a jQuery XMLHttpRequest (jqXHR) object, which is a superset of the browser's native XMLHttpRequest object. To make a request, you need to create a new instance of the XMLHttpRequest object. XMLHttpRequest is supported by all browsers. Despite its name, XMLHttpRequest does not only retrieve XML but can also be used to retrieve any type of data including HTML, JSON, text, blob, etc. XMLHttpRequest (XHR) is the underlying object used by most HTTP request libraries to interact with servers. This article lists some of the ways you can use. If you are doing front-end development, making an HTTP request in Javascript is something that you must learn. When a user is browsing a website, the client (browser) will need to make HTTP requests to the server to retrieve the data needed.Īs of 2022, 98% of the websites use Javascript on the client side for webpage behaviors. The back-end focuses on the application logic while the front-end focuses on things that users see.Īlthough both types of developments are separated, they need a medium to communicate with each other. They can also be known as client-side and server-side. ![]() Web development can be categorized into front-end and back-end. ![]()
