Node.js is a strong framework built on JavaScript that allows developers to work not only on the backend but also on the front end. It is a common misconception that a node is a backend framework, which is untrue. While JavaScript is a programming language that can develop scripts to run those scripts, we need a runtime environment, which Node provides. Since it was created in 2009, it has changed a lot and become even more powerful, and it holds the largest market share in 2024.

Evolution Of Node.js

Here's the Node.js roadmap, which has grown over the years:

  1. Node.js 0.1.0 (2009): The initial release of Node.js laid the foundation for its event-driven, non-blocking I/O architecture. It included the V8 JavaScript engine, an event loop, and a set of core modules.
  2. npm (2010): The Node Package Manager (npm) was introduced to manage dependencies and package distribution for Node.js applications. It quickly became a crucial tool in the Node.js ecosystem.
  3. Stable Releases and Growing Ecosystem (2010-2012): Node.js went through several stable releases, expanding its ecosystem rapidly. Developers started building modules and frameworks, contributing to the growth of the Node.js community.
  4. Node.js and io.js Reconciliation (2015): The Node.js and io.js communities reconciled under the Node.js Foundation, leading to the formation of the Node.js Foundation. This collaboration aimed to streamline development efforts and combine the best features from both projects.
  5. Node.js 4.0.0 (2015): The release of Node.js 4.0.0 marked the end of the Node.js and io.js schism. It incorporated features from both projects and set the stage for future releases.
  6. Long-Term Support (LTS) Versions (2015-2022): Node.js adopted a Long-Term Support (LTS) release strategy, ensuring stability and backward compatibility for enterprise users.
  7. Introduction of Node.js 6, 8, 10, 12, 14, and 16 (2016-2022): Node.js continued to evolve by introducing new versions, each bringing enhancements, performance improvements, and new features. 
  8. Adoption of ECMAScript Modules (ESM): Node.js began to support ECMAScript Modules, the official standard for organizing and declaring dependencies in JavaScript, alongside the CommonJS module system.
  9. Node.js 14 LTS and 16 Current: Node.js 14 was the LTS version, while Node.js 16 was the current release. Each version brought improvements to performance and new features.

Core Components Of The Node.js

  • Node Package Manager (NPM): NPM helps you organize and manage different parts of code, known as packages. Adding, removing, or monitoring these is a breeze with NPM.
  • V8 JavaScript Engine: This engine runs your JavaScript code smoothly and efficiently. 
  • Event Loop: The Event Loop is like Node.js' multitasking brain. It smartly handles tasks, ensuring your programs can juggle many things simultaneously without complicating them.
  • Callbacks: They're handy for keeping things in the right order, ensuring tasks happen when they should.
  • Streams: Streams in Node.js let you handle bits of data at a time, which is super useful when dealing with lots of information.

Ultimate Roadmap To Learn Node.js

We have listed down the most important points on the Node.js roadmap:

1. Javascript

Be very clear on the concepts of javascript. Learn the syntax and basic operations, DOM manipulation, scope, callbacks, sync, and wait.

2. Learn LINUX

Spend much time learning and getting used to the Linux interface and command prompts.

3. Databases

Learning SQL, Postgres. MySql and NoSql, like MongoDB, are two of the most important parts of this roadmap. It is about structuring data models to ensure effective queries without holding up on the API. We recommend focussing on the RDBMS.

4. API Clients

Start querying and learning about the API clients, GraphQL, and REST apisAPIs. The REST API is the most commonly used, but we suggest exploring GraphQL for greater understanding.

FAQ

1. Is Node.js in demand in 2024?

As per the trend in 2023, node.js has been quite popular among web development frameworks, capturing almost 50% of the market share. Its ease of usability, scalability, and performance have made it a top choice. Therefore, even in 2024, it is in high demand and still capturing more than 45% of the market share among web frameworks available.

2. What is the current stable version of Node.js?

The current version of node.js is version 21, effective up to April 2024. We might be seeing a newer version of node.js after April 2024.

3. How much time will it take to learn Node JS?

Node is a framework written in Javascript. If you're familiar with and experienced in Java programming, which most developers are, a month is more than enough to learn how to build a basic API. If you're new to programming and Javascript, you must learn programming and its concepts to master the Node.

4. What are the best practices for staying updated with Node.js changes?

If you require multiple versions of Node JS, then we recommend using Node Version Manager (nvm).
