Node.js has topped the charts and become the most-used web development framework with a whopping 42.7% of developers worldwide using it. Source: statista.com
Before we jump right into the list of best NodeJS libraries that we have curated, let us first understand why the developer must consider using the library for Node JS development in the first place and how to choose one.
A library in web development is a set of prewritten code or useful resources that developers can use to perform common tasks, optimize tasks, add specific functionality, or solve specific problems.
This set of codes and resources enables the developers to eliminate the time, effort, and cost consumption of writing the same code over and again. Further, the reusable code and resources of the libraries are pre-tested for multiple environments/use cases.
However, the only struggle a developer has to face if of choosing a library as there are hundreds of libraries out there for any framework. Here are some of the considerations that you can make to choose the right library for your development requirements
Now that we know the usefulness of these libraries and the difficulty of finding a suitable library for any development requirements, we have compiled a list of top NodeJS libraries to help you with effective and quick decision-making.
Let us dive in and explore each of these Node JS libraries further in detail.
Fast, unopinionated, minimalist web framework for Node.js. – expressjs.com
Its easy integration with widely used databases (MongoDB, MySQL, etc.) makes it simpler for Node.js developers to store and retrieve web application data along with easier management of servers and routes.
The backend web developer can use this NodeJS library when developing single-page, multipage, and hybrid web applications apart from it, Express is also used to build RESTful APIs, server-side rendering, and microservices.
Features of Express JS:
Build powerful, scalable applications, with minimal overhead and full out-of-the-box functionality – your code, your way. – hapi.dev
Created by a mobile team led by Eran Hammer at Walmart Labs, Hapi has made its way from being a solution created to handle Walmart’s Black Friday sale to a framework of choice for developing the enterprise-grade backend.
No more need to sacrifice quality for performance with this DevOps-friendly library Hapi.
It is one of the most chosen NodeJS libraries by NodeJS developers to develop Network applications, server components for Single Page Applications (SPAs), eCommerce web apps, JSON APIs for web applications, static or data-driven websites, and HTTP-based software applications.
Features of Hapi.js:
Socket.IO is a library that enables low-latency, bidirectional, and event-based communication between a client and a server. – socket.io
Created by Guillermo Rauch, this open-source cross-platform NodeJS library is built on top of the WebSocket protocol. Owing to its bidirectional client-server compatibility, it is used by the developer in applications that require real-time features (live sports updates, alerts, real-time dashboards, or live location tracking).
Its compatibility with web, mobile, and desktop platforms adds to its ability to make an application that works seamlessly on multiple platforms increasing accessibility for the end users making it one of the few Node JS libraries.
Features of Socket.io:
Node JS developers use this library for creating composite functions, iterating arrays, objects, or strings, and manipulating or testing values.
Features of Lodash:
Sequelize is a modern TypeScript and Node.js Object Relational Mapper (ORM) for Oracle, Postgres, MySQL, MariaDB, SQLite, SQL Server, and more. – sequelize.org
From defining models to associations between models, this NodeJS library enables the developer the ease of defining models and better handle heavy lifting.
Features of Sequelize:
The ethers.js library aims to be a complete and compact library for interacting with the Ethereum Blockchain and its ecosystem. – ethers.org
Created by Richard Moore, Ethers.js is an open-source (via MIT License) often used for Ethereum Blockchain development. it is one of the best NodeJS libraries as this simple and complete library is a replacement for web3 and ethereum.js.
Features of Ethers.js:
Passport is middleware for Node.js that makes it easy to implement authentication and authorization. – passportjs.org
With a lightweight code base, this flexible and modular library works as an express-compatible authentication middleware for Node.js using an extensible set of plugins known as strategies. This NodeJS library can be easily integrated into any Node and Express-based app to plug in any strategy to get the functionality for authentication in the app.
Features of Passport.js:
Elegant Mongodb object modeling for node.js. – mongoosejs.com
Mongoose.js is a node.js- and schema-based Object Data Modeling (ODM) library for MongoDB and Node. Js. The object modeling and handling are facilitated by the configuration for the Mongoose model – Schematypes. This is one of the very few Node JS libraries which enables the Node.js coders to manage the relationships between data and provide schema validation.
With it, they can also reduce the time consumption for writing the validations and boilerplate business logic. The cherry on the top is its additional functionalities like built-in type casting, business logic hooks query building, and more.
Features of Mangoose.js:
Winston is designed to be a simple and universal logging library with support for multiple transports. – github.com
This is one of the most popular logging Node JS libraries. It is flexible, open-source, simple, and community-driven which offers support for multiple transports (storage device for your logs). It eases the task of searching and analyzing logs by providing log archives.
This NodeJS library’s flexibility and extensibility are better reflected in decoupling different aspects such as log storage, levels, and formatting making the APIs independent. Further its, variety of logging options and transport mechanisms enables the Node developers to have logs that write multiple outputs (file, remote server, or console).
Features of Winston:
Puppeteer is a Node.js library that provides a high-level API to control Chrome/Chromium over the DevTools Protocol. – pptr.dev
Built by Google, It is an open-source NodeJS library rather referred to as a browser testing framework or an automation tool by the coder community. It is utilized by NodeJS programmers to perform performance testing, web scraping, screenshot testing, and automation. Further, the developer can also seamlessly integrate tools like TeamCity, Jenkins, and TravisCI with this NodeJS library.
Features of Puppeteer:
Features of Jest:
Node JS has a rich suite of libraries that help the developer with various particular development requirements.
By using these Node JS libraries they avail the following benefits:
The developer can either utilize a specific NodeJS library from the above-listed top Node JS libraries or can use multiple of them in their Node.js code.
