In Silicon Valley, Node is the most popular technology. Any software developer with this ability will have many job options at their fingertips. Social media apps, video chat engines, real-time trackers, and online games are just some of the applications you can create with this tool. In addition to Paypal, LinkedIn, Uber, Yahoo, Medium, GoDaddy Groupon, and Walmart, many other large companies have switched to NodeJS as their technology stack.
NodeJS is becoming increasingly popular among programmers for all of the reasons outlined above.
What’s the next step in the process?
What are some good topics to cover?
Which NodeJS framework should I learn first?
Is it better to learn from a book or an online tutorial to learn the concepts? Take a deep breath, relax, and we’ll walk you through everything you need to know to become a NodeJS developer step-by-step and start to Learn Node JS Basics.
- Learn about the NodeJS Architecture:
When using NodeJS, all client requests are handled by a single thread because of the event loop model architecture. NodeJS’s event-driven architecture makes it possible to control many client requests simultaneously.
- NodeJS installation:
Getting NodeJS up and running is a breeze. The latest stable version of NodeJS is obtained from the NodeJS website. Depending on the operating system and its configurations, you can begin working on NodeJS immediately after installing it. Make sure to have a minimum of 4GB of RAM to run NodeJS on your computer.
- NPM (Node Package Manager):
In NodeJS, the Node package manager is one of the most fundamental concepts to master. NPM is introduced to the user after the installation. More than 800,000 libraries are available for use with NPM. NodeJS features are built with the help of these pre-built libraries. As a result, you won’t have to start from scratch. It’s easy to use the npm command to install the necessary library for your application. As a result, these libraries significantly impact the speed of creating new applications. You can Learn Node JS Basics and move to all these topics.
- JSON File:
An understanding of JSON files is also a necessity when working with NodeJS. Create a JSON file as the first step in any NodeJS project. Package.json is the manifest file in any project, and you can find it in your application by searching for the file name. It includes the project’s metadata. In other words, it keeps track of and manages all of the project’s packages and dependencies, as well as the script itself. You can open this file for any questions about which packages or dependencies are used in the application.
- Node.js Fundamentals:
It is the point at which you get your hands dirty with the scripting of NodeJS. Like other programming languages, you begin by learning how to print “Hello World!” in JavaScript before moving to more advanced concepts like variables, data types, operators, and functions. Before diving into NodeJS development, make sure you grasp the JavaScript concepts listed above.
- File System:
To move away from the console and instead use files for reading and writing data, you’ll need to master the fundamentals first. NodeJS use the fs module to access the physical file system from a directory.
- Events:
Events drive many core features of NodeJS, and the event-driven nature of NodeJS is reflected in its design. An event acts as a signal that something has happened in the application. Event modules in NodeJS allow programmers to implement new kinds of events. Because all NodeJS applications are built on a single-threaded and event-driven architecture, they all support concurrency.
- HTTP Modules:
The NodeJS framework is made up of powerful HTTP modules. Server-side networking applications heavily rely on HTTP modules. The HTTP module in NodeJS makes it simple to create a REST API.
- Frameworks:
Every server-side language has its own set of frameworks to enhance the application’s functionality. Writing code from scratch takes a lot of time and effort to implement new features in any app. So by using the framework in your application, you will be able to build any quality faster and with less effort. Here are a few popular NodeJS frameworks.
- js
- js
- AdonisJs
- NestJs
- Sails
- KoaJS
- LoopbackJS
- Databases:
To create a fully functional application, you should be familiar with a wide range of NodeJS concepts. Nevertheless, what about the data you need to keep in your application? The data must be stored in a database, as with any other application. Depending on the application type or requirement, you can use any database and configure it with NodeJS. Below are some of the best NodeJS-compatible databases.
Relational
- SQL Server
- PostgreSQL
- MariaDB
- MySQL
Cloud Databases
- CosmoDB
- DynamoDB
Search Engines
- ElasticSearch
- Solr
- Sphinx
NoSQL
- MongoDB
- Redis
- Cassandra
- CouchDB
- Testing:
All applications must be thoroughly tested before making them available to the general public. The Node is in the same boat. Learning NodeJS requires knowledge of NodeJS testing frameworks and libraries, as well. Check out the following NodeJS application testing frameworks and libraries.
The three types of testing are unit, behavior, and integration.
Unit, Behavior, Integration Testing
- Jasmine
- Jest
- Enzyme
- Chai
- Mocha
E2E Testing
- Selenium
- Puppeteer
