A to Z of Node.js Modules

Introduction — Node.js

Node.js is an open source platform for creating applications that uses JavaScript on server side as well as on the client side. JavaScripts usage amongst the developer community is growing at a very rapid pace. It is the most popular language in a recent survey conducted by Stack Overflow.

Its runtime environment interprets JavaScript using Google’s V8 JavaScript engine. Node.js has an event-driven architecture capable of asynchronous I/O that makes it lightweight and efficient. Node.js’ package ecosystem, npm, is the largest ecosystem of open source libraries in the world.

Here is a A to Z list of node modules that will extend the capability of your node.js application.

Hapi : is a streaming build system that helps you automate painful or time-consuming tasks in your development workflow.

Http-server : is a simple, zero-configuration command-line http server. It is powerful enough for production usage, but it’s simple and hackable enough to be used for testing, local development, and learning.


Inquirer : A collection of common interactive command line user interfaces.

Jshint : Static analysis tool to detect errors and potential problems in JavaScript code and to enforce your team’s coding conventions.


Koa : Koa is web app framework. It is an expressive HTTP middleware for node.js to make web applications and APIs more enjoyable to write.


Lodash : The lodash library exported as a node module. Lodash is a modern JavaScript utility library delivering modularity, performance, & extras.

Less : The less library exported as a node module.


Moment : A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.

Mongoose : It is a MongoDB object modelling tool designed to work in an asynchronous environment.

MongoDB : The official MongoDB driver for Node.js. It provides a high-level API on top of mongodb-core that is meant for end users.


Npm : is package manager for javascript.

Nodemon : It is a simple monitor script for use during development of a node.js app, It will watch the files in the directory in which nodemon was started, and if any files change, nodemon will automatically restart your node application.

Nodemailer : This module enables e-mail sending from a Node.js applications.


Optimist : is a node.js library for option parsing with an argv hash.
