How to Start Node JS journey and practices for beginners


Undoubtedly node.js is one of the buzzing topics in the field of backend as well as front end development sector. Node. js is a platform built on Chrome’s JavaScript runtime for easily building fast and scalable network applications. Node. js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Even big companiesAmazon, Netflix, eBay, Reddit, LinkedIn, Tumblr, and PayPal all use Node JS.

I can talk about it the whole day with no full stop. But the motive of this blog is not about what node has to offer but it is to help all the new bees out there who are thinking to start there node journey. 

Below I have included five important steps that will help you as a beginner to draw that road map of your node journey correctly.

Understand why node over other technology

 I have seen many people jumping into node without knowing why in the world we use node over other backend services  As there are hundreds of them. It’s a better practice to have a good knowledge about why node over other backend services? 

With more than 168K websites using Node.js, organizations using the framework are happy and a number of clients are looking forward to increasing the usage of the framework in the upcoming years.

This will really pump you up and provides you with great motivation to keep you going. So, indulge yourself in understanding the market value of node, understanding working statistics, compare and get into it. This video might help you know why?

Learn and master Javascript 

Javascript is the backbone of node.js. By the way, Node.js is just a javascript framework. So, if you ever try to abruptly jump into node.js without learning javascript you are more likely to fall into this clear loop of confusion and you will be doing nothing except for wasting your time and energy. 

So, take your time to start from scratch, i.e. learn javascript, do some javascript projects. First, the basics and the list goes on. Get your hands dirty and code as much as you can. 

Confused,  what javascript project to start as a beginner?

This might help you.

Understand the architecture in which node works

Before jumping into the coding world you need and you must know about the internal architecture of node. And when I mean internal architecture it’s not only knowing that it is single-threaded and Follows reactor pattern. 

But node is more than that you as a node js developer must know about how demultiplexer in node manages events, how event loop works, callbacks, thread pool, and many more. Have that clear picture of the architecture inside your head so that you can put your imagination into practice.

Start to learn from the basics 

Now, after working so hard you are finally ready to start your node coding. Start from the basics, then move further start learning about templating engines, basic routing, dynamic routing, node.js with databases like SQL and NoSQL, Building restful APIs, web sockets testing, frameworks related to the node.

The popular Node.js frameworks have been integral in taking the framework to the heights of success in the year 2019 and are pulling up their game harder for 2020. This language is amazingly easy to learn.

“The group of Latin American Node JS learners showed a 58% increase in ease of learning in 2018.”

Know what works perfectly with node and what doesn’t 

Although Node.js has many valuable virtues and works well for many products it might not be the best choice for every project. Node.js should be considered for any real-time applications intended to run on various devices. If your product requires fast prototyping or performs CPU-intensive tasks (like generating graphics) there are other technologies, that will do a better jobSo, it’s very important to understand whether or not the node.js fits within your project or not

So, it’s very important for you to understand that learning anything new requires consistency. Nothing is going to come to you overnight. You need to try hard, explore yourself, and yes accept the failure that might come your way, these are the thing that will help you to grow and be a better learner. So keep calm and start right away.
