Hey gang, in this Node.js tutorial we'll take a look at how we can gather information from a user request & then send back a response to the. Node-fetch is a light weight module that brings the browser library window.fetch to Node.js with minimal code. In Postman, the script execution order for a single request looks like this. It may take a bit more effort to get the data you want, but is a great utility if you don’t want to add too many dependencies to your codebase or want access to its low level functionality. Make XMLHttpRequests from the browser Make http requests from node.js Supports the Promise API Intercept request and response Transform request. based on Node.js that allows you to add dynamic behavior to requests and. It uses a native promise library but you can replace it with another one you like. The library makes conscious trade-offs when following stream specs and WhatWG fetch standard implementations. The simplest and most popular way to perform an HTTP request in Node.js is using the Axios library. One other problem is that this module does not support HTTPS by default, so we need to require the https module instead if the API we are using communicates over HTTPS. Notable features of this Node.js HTTP request client are: Perform consistently when working with window.fetch API. Before we dive into code and description, make sure that you have installed the latest LTS versions of Node.js and npm on your machine. This is fairly trivial if it is JSON formatted, but it is still an extra step. You also need to parse the response data manually. You’re required to receive response data in chunks rather than just providing a callback function to be executed as soon as all of the data is received. Much of the HTTP, and the HTTPS, module’s functionality is fairly low-level. The following code will send a GET request to NASA’s API and print out the URL for the astronomy picture of the day as well as an explanation: The downside is that it isn’t very user friendly compared to other solutions. ![]() With this module, you can just plug and go without having to install external dependencies. HTTP – the Standard Libraryįirst on our hit parade is the default HTTP module in the standard library. We’ll be using NASA’s Astronomy Picture of the Day API as the JSON API that we are interacting with in all of these examples because space is the coolest thing ever.īefore moving on, make sure you have up to date versions of Node.js and npm installed on your machine. Let’s take a look at some of the most popular ones. When it comes to Node.js there are a fair amount of solutions to this problem both built into the language and by the community. Making HTTP requests is a core functionality for modern languages and one of the first things many developers learn when acclimating to new environments.
