Node js Roadmap for Beginners DEV Community

There are many libraries and packages available for the nodejs and its popularity increasing every day. NodeJS comes with event-driven features and a lot of Node’s core functionality is based on the concept of events. Event is basically a signal that indicates something has happened in the application. In NodeJS Event modules are available for developers to create and handle custom events. Applications built on NodeJS support concurrency because they all are based on single-threaded and event-driven architecture. From this step, you actually get your hands dirty in the scripting of NodeJS.

What you need are the most common languages ​​since node.js is based on Javascript (hence the .js extension of your name). If you are a newbie or intermediate Node.JS developer, this article contains the best resources to learn node.js for you. This is the first question that comes to mind when we want to learn new technology. If you have some troubles or you just want to optimize your server I recommend you to check the video below and do your own research.

But in case if you are a complete beginner who’s looking to master Node.js in the minimum possible time then you must learn the following concepts before you deep dive into the Node.js environment. Real-time apps are highly popular among businesses in gaming, e-commerce, social media, and other niches. These applications function within a time frame giving their users a sense of immediate response. The latency in real-time apps is measured in seconds, therefore, they are used for building online games, videoconferencing applications, instant messaging apps, and others.

With microservice architecture, software developers can build their apps in small and fast iterations, easily scale their apps, and develop their apps faster. Node.js uses the Docker containerization https://wizardsdev.com/en/vacancy/middle-nodejs-developer/ platform and Kubernetes Services to build microservice architecture solutions. Node.js is a front and back-end open-source and cross-platform development framework created in 2009 by Ryan Dahl.


Businesses in gaming, e-commerce, social networking, and other industries have embraced real-time apps. These apps operate in real time, providing their users the impression of instant reaction. Real-time apps have a latency of seconds and are used to create online games, videoconferencing applications, instant messaging apps, and other applications. All of these apps demand a lot of processing power on the backend, which Node.js excels at. If you are a frontend developer looking to master some backend skills then you don’t have to spend a huge amount of time learning JavaScript before getting started with building Node.js applications.

Field search, boolean queries, phase questions, fuzzy queries, spell check, auto-complete, and many more sophisticated real-time searching features are available. Explore how to become a mean stack web developer by checking out here.

Like other programming languages you learn how to print “Hello World! ” and then you start learning the basic concepts like variables, data types, operators, functions, etc in JavaScript. Make sure that you understand all these concepts in JavaScript very well before you move to build the actual application in NodeJS. Before you start your journey with NodeJS you should have a clear goal in your mind that why do you want to learn NodeJS? Do you want to build some web applications, to start your own business or your purpose is to get a new job?

Node.js Developer roadmap

Community created roadmaps, articles, resources and journeys to help you choose your path and grow in your career. In Node.js you will be handling a lot of asynchronous programming and for that, the following concepts are recommended to learn. Backend will become important in future, as AI is approaching in Frontend development backend will open opportunities for developers to do some real shit. Fortunately, the
Model-View-Controller frameworks have made constructing dynamic purposes
effortless. Moreover, if your developer makes use of client-side rendering in
Node.js, you can limit latency and store bandwidth. •Nodejs
is based totally on the JavaScript language, so there is no want to study a new
language separately, which lowers the studying threshold.

Microservice Architecture

It runs on the Chrome V8 engine with its own compiler, interpreter, and runtime environment. This allows Node.js to execute JavaScript code out of the browser which makes Node.js applications super-quick and efficient. Like every other server-side language, NodeJS also provides a number of frameworks that help in building the application with better features. It’s a time-consuming process to write code from scratch to build various features in any application.

To access the physical file system from a directory NodeJS uses the fs module. In this tutorial, we will look at the tools and languages needed to be known to be a successful nodejs developer. This roadmap provides a guide for developers who wants to learn Nodejs from scratch and improve their knowledge about nodejs. Before REST, APIs were developed around a remote procedure call (RPC) and the APIs looked like some locally executed code. Many technologies tried to solve this problem using RPC-like stacks to hide the root problem and after that REST was introduced to build web-based APIs in a better way. BCA Careers are one of the most popular and plentiful jobs available in India and worldwide.

So using the framework in your application makes your work easier and you build any kind of feature at a faster speed. The Node package manager is one of the most important core concepts to learn in NodeJS. NPM comes with 800, 000+ libraries that can be used for different purposes.

  • Learning JavaScript is one of the best investments you can make as a developer.
  • JavaScript is known to be a type-less language, Typescript “solves” this issue by bringing types (strings, numbers, etc), and a number of other features, to your code.
  • Based on the modular thinking of nodejs, it distributes functions in modules, so that there is a connection between modules and modules.
  • • Nodejs did now not redevelop the runtime surroundings however selected the quicker V8 browser kernel as the runtime to make certain Nodej’s overall performance and stability.
  • GraphQL is a fantastic alternative to REST since it makes use of APIs that prioritise providing clients with exactly the data they need.
  • To become full-stack engineers, many front-end developers learn Node.js.

Choosing a JavaScript framework will introduce lots of commodities in your workflows. With over 12 years of active development, MongoDB is one of the most popular NoSQL Databases to date. A minimal and flexible Node.js framework that will help you creating APIs effortlessly thanks to a myriad of HTTP methods and middleware. Express.js powers thousands of backends around the world, suitable for the most diverse REST APIs.
