Overview of this book

Node.js revolutionizes server-side JavaScript development and empowers developers to build efficient, scalable, and versatile applications across a range of use cases. This book is written by a Node.js core collaborator and releaser and is the only book for beginners on Node.js. It takes you on a progressive learning path that will give you the skills needed to leverage Node.js. You’ll learn Node.js fundamentals and refresh your knowledge of JavaScript before transitioning to the development of modern web applications using Node.js, Express.js, and MongoDB. You’ll get hands-on with complex topics such as asynchronous programming, npm libraries, event-driven patterns for HTTP servers, RESTful API, and JSON Web Tokens. The final chapters will walk you through the deployment process, offering insights into various strategies, including bare metal setups, virtual machines, and containerization with Docker. You’ll also be guided through the use of Process Manager 2 (PM2) for efficient process management. By the end of this Node.js book, you'll have the skills to craft, test, and deploy Node.js web applications confidently and use this powerful stack in your day-to-day projects.

Mastering HTTP

Now that we have a better understanding of the HTTP concept, let’s take a look at the different parts of HTTP that we need to understand in order to build a web application.

We have already seen the request and response, but let’s take a deeper look at the different parts that compose the request and the response (headers, payloads, versions, and methods).

HTTP headers

Each request and response has a set of headers. These are key-value pairs and provide additional information about the request or the response.

While both the request and response headers may look similar, they are not the same, although they do share common key-value pairs.

Request headers

We will start by analyzing in Figure 9.6 what is included in the request header:
