Basic knowledge of web servers, HTTP, and RESTful API will help you understand building web servers and interacting with databases.
Understanding how to use Git for version control will be necessary while working with others on projects and managing your codebase.
Here is the Node.js learning roadmap for mastering backend development:
Understanding the basics of Node.js architecture is essential. Non-blocking I/O is further molded into a model assisting in event-driven programming, thus allowing for quick and scalable network application development. Discuss the history and evolution of Node.js from 2009 until today (with version 20.0.0). Understand its core features and why all major companies are implementing Node.js.
Single-Threaded Event Loop
One of the crucial features of Node.js is the single-threaded nature of its event-driven, or non-blocking, I/O architecture. Unlike traditional server-side technology that relies on vertically open parallel threads to handle multiple client requests, Node.js relies on a single-threaded event loop for handling various client requests, thus allowing for high throughputs.
Installation on your machine with Node.js is simple. Installing the latest stable version is possible from the official Node.js website. Installation will differ according to your operating system, so follow the installation guide and check the installation by sending in a simple command in your terminal that checks for the Node version.
The npm is bundled with Node.js and is the largest software registry. You learn to use it to install any libraries and dependencies for your projects. Using npm is powerful because it can integrate third-party packages, thus speeding up coding time.
You need to know the basic structure of any Node.js project. The package.json file is your project's principal place of metadata, holding dependency lists, scripts to be run, and configuration options. You learn how to configure and create this file, which is central to Node.js project management.
Basics of Scripting
To begin with Node.js, writing simple JavaScript programs to familiarize yourself with how Node.js works is essential. The language will discuss variables, data types, operators, and control flow. All Node.js applications are in JavaScript; hence, a strong foundation in the language would be crucial.
Learn how to use Node.js to access the file system. The fs module should be able to read from and write to files. File handling is essential to all applications that require data.
Events are at the heart of Node.js. Learn to handle events with the built-in events module and understand how Node.js's non-blocking I/O model manages multi-requests.
The HTTP module is the backbone for web servers and handling HTTP requests with Node.js. Learn how to set up a simple server and utilize this approach to build basic RESTful APIs.
