Awesome Node.js Tools, Libraries and Resources

Node.js is equipped with a rich ecosystem of tools, libraries, and frameworks to help developers build their application faster, safer, and follow the standard industry guidelines on software development.

While there are hundreds of thousands of packages registered in the official node package manager repository, we have shortlisted a few based on the reputation and usability for a day to day software development.

Let's jump in directly and check out some of the awesome Node.js tools, libraries, and frameworks. If you are new to Node, you can read our entry-level complete Node.js tutorial for beginners to get started.

Web frameworks

Here are some of the popular and widely used web frameworks available in the Node.js ecosystem.

• Express - A complete web application framework to develop various types of web applications such as Web server, API server,etc. We built this site on top of Express framework and this article is served by an Express router :)

• Molecular - A mature, fast and powerful microservices framework for Node.js.
• AdoniJS - is a framework to write micro-services easily.

HTTP and Networking Stuff

Node.js is widely used in building networking applications. There will come a scenario where you as a developer asked to integrate third-party APIs such as payment API, invoice API, etc. To handle these tasks, you can use the libraries mention below.

• Axios - A widely used HTTP client for Node as well as the browser.
• got - A simple and lightweight interface to make HTTP calls.
• HTTP proxy - a very useful tool to build a proxy server effortlessly especially in a microservice architecture.
• HTTP fake backend - a huge time saver tool. Allows you to create a fake backend server for the test and demo apps.
• download - utility to download files from a URL and save it in file system.
• getmac - get the MAC address of your computer.

Database drivers and ODM/ORM

There is really no need to mention how important the database is for your application. Node.js can be integrated with almost every popular database.

• MySQL - A pure JavaScript based driver to integrate with MySQL database. We have written a detailed tutorial about Node.js and MySQL.
• MongoDB - A MongoDB database driver. Refer this tutorial to learn how to use this driver to connect to MongoDB.
• Mongoose - A MongoDB object data model i.e ODM.
• PostgreSQL - A database client for PostgreSQL database.
• Redis - A client for redis key value database.
• LevelUP - A levelDB database.
• Couchbase - A client for a couchbase database.
• Waterline - A database agnostic that can interact with one or more database.

Logging

Logging is an essential part of any web application. Node.js has some of the best logging library available. I personally uses winston a lot in my projects. It has rich set of plugins to extend the logging feature as per the requirenments.

• winston - Asynchronous multi-transport logging library.
• pino - Fast logging library.
• storyboard - a real time and colorful log.

Documentation

The only thing which almost every developer hate is creating a documentation. I know, I do too. But, it's an important thing to create a well written documentation as you write your beautiful code.

• JSDoc - API documentation generator similar to JavaDoc.
• documentation - library with modern JavaScript support.
• ESDoc - documentation generator with ES2015 support.

Control flow

Node.js is asynchrnous in nature and it's little different than what we used to in high level languages such as Java, C++,etc. We can leverage libraries mentioned below to make our life little bit easier while writing Node.js application.

• async - a popular library to write asynchronous code in JavaScript using callbacks.
• Bluebird - a library to handle and write asynchronous code using promises.

Streams

• get-stream - library to get a stream as a buffer or string.
• multistream - combine multiple steams into a single stream.
• into-stream - convert existing buffer, array, string into a stream.

Real time

Node.js can be used to build a real time systems. I have used these library in some of the projects and they are pretty good.

• Socket.io - A really useful library to develop real time web application.
• uWebSockets - A library that support event based real time features.
• deepstream.io - A scalable real time framework to develop advanced application like games,etc.
• MQTT - A pubsub library to develop applications with lightweight communication.

Authentication and Authorization

When you are building any web application, the most common part is going to be user authentication. You don't need to develop the modules again, Node.js libraries will cover it for you. The libraries listed below are tried and test library in thousands of projects.

• Passport - A widely used authentication library that support wide range of SSO.

• node-resque - Job queue based on Redis.
• rsmq - Message queue based on Redis.
• sqs-consumer - library to handle amazon simple queue service in your application.

Process Management

Node.js as a process is tricky to manage. Thanks to the libraries mentioned below especially PM2, managing a Node process is piece of cake.
