Overview of this book

A key technology for building web applications and tooling, Node.js brings JavaScript to the server enabling full-stack development in a common language. This fourth edition of the Node Cookbook is updated with the latest Node.js features and the evolution of the Node.js framework ecosystems. This practical guide will help you to get started with creating, debugging, and deploying your Node.js applications and cover solutions to common problems, along with tips to avoid pitfalls. You'll become familiar with the Node.js development model by learning how to handle files and build simple web applications and then explore established and emerging Node.js web frameworks such as Express.js and Fastify. As you advance, you'll discover techniques for detecting problems in your applications, handling security concerns, and deploying your applications to the cloud. This recipe-based guide will help you to easily navigate through various core topics of server-side web application development with Node.js. By the end of this Node book, you'll be well-versed with core Node.js concepts and have gained the knowledge to start building performant and scalable Node.js applications.

Using http module to make HTTP requests

Programs and applications often need to obtain data from another source or server. In modern web development, this is commonly achieved by sending an HTTP GET request to the source or server. Similarly, an application or program may also need to send data to other sources or servers. This is commonly achieved by sending an HTTP POST request containing the data to the target source or server.

As well as being used to build HTTP servers, the Node.js core http and https modules expose APIs that can be used to send requests to other servers.

In this recipe, we're going to use the Node.js core http and https modules to send both an HTTP GET request and an HTTP POST request.

Getting ready

Start by creating a directory named making-requests for this recipe. We'll also create a file called requests.js:

$ mkdir making-requests
$ cd making-requests
$ touch requests.js
