Package Managers for JavaScript

The appearance of package managers entirely changed JavaScript routine processes, since they’ve solved a set of problems and simplified the use of the language. First of all, JavaScript package managers introduced a new reliable approach to third-party software. That’s why you only need to know how a certain tool works instead of learning the algorithm of the installation process, or how the software is built, compiled, and integrates with the system. Besides, you get a dependency management solution with every JavaScript package manager. The software knows the requirements of every package, so it automatically installs all the necessary components in order to satisfy the tree of dependencies.

In addition, every JS package manager constantly updates your packages, so you always get the latest features; or you can perform the updates manually. Moreover, some package managers provides the ability to get new features or solve current problems with the help of new software. Just go to the tool of your choice and find some new packages there.

If you develop packages, you can also rely on package managers, since some of them provide tools for creating packages ready for distribution. As a result, you can easily share your software  among the community of JavaScript developers.

In the following blog post, we shed light on the most popular JavaScript package managers: npm, Bower, Volo, Grunt, and Ringojs. All of them are described below.

npm

JavaScript Package Managers: npm

npm is a JavaScript package manager for Node.js. It has begun as an open source project aimed at helping JS developers to share packaged code modules. Now, npm, Inc. is the company that also offers a public collection of Node.js packages, web and mobile apps, routers, robots, and tons of other useful things called the npm Registry. Besides, it is necessary to mention the command line client which is also dubbed. This tool essentially simplifies such routine processes as the installation and publishing of packages.

So, npm makes it easy to share and reuse code, as well as update what you’re sharing. To find out more about this JavaScript package manager, watch the following video:

The most popular npm packages are:

  • browserify. With the aid of this npm package, you will be able to utilize a node-style require() for organizing your browser code and loading modules installed via npm package manager. Browserify works with the require() calls in your app. It recursively analyzes them in order to create a bundle which can be served up to the browser in a form of a single <script> tag.
  • express is a fast and minimalist web framework that offers robust routing, high performance, advanced test coverage, HTTP helpers, support for 14+ template engines, content negotiation, and other useful features.
  • pm2 is a production process manager designed to simplify your work with Node.js apps. It provides a built-in load balancer, as well as allows your apps to stay alive forever: due to pm2, you can reload them without downtime. This npm package also provides the ability to facilitate common system tasks.
  • grunt-cli is a command line interface for Grunt. This JavaScript package manager will be discussed later in this post.
  • karma is a  simple tool for executing JavaScript code in multiple browsers. Its main purpose is to provide you with easy and fast test-driven development.
  • bower is a package-agnostic, generic, unopinionated solution for front-end package management which runs over Git.
  • cordova is a command line tool for building, deploying, and managing Cordova-based apps.
  • CoffeeScript. This package provides the ability to use CoffeeScript – a language that compiles into JavaScript.
  • gulp will be helpful, if you are looking for a streaming build system.
  • forever is a simple CLI solution which provides the opportunity to check that a node script runs continuously.
  • statsd is a simple network daemon for Node.js. It listens for sent over UDP statistics and sends aggregates to pluggable backend services.
