How To Contribute To Open Source Javascript

Open source software (OSS) has become a core part of all web application development, but contributing to it can be quite intimidating. Open source isn’t just free software, it is free and open collaboration. Developers are able to set up their own private development repositories, submit bug fixes and new features, and submit pull requests to their integration repositories. This article will discuss how to contribute to an open source project within Github as a developer.

This article aims to give you a few tips on how to show gratitude and make yourself a valuable addition to the open source community. I’ve been using open source software since middle school, primarily as a student with limited access to computers. Now as an adult, I find myself utilizing open source projects in my professional life as well. Both are rewarding experiences, but each requires a different approach.

Node.js is an Javascript Open source runtime environment. It is built on the Chrome browser’s V8 engine. Without a separate runtime environment, JavaScript can only be run using the environments of browsers. But Node.js enables JavaScript to be used as a standalone scripting language, like Python.

Developers can now test JavaScript on their own machines, instead of having a browser do it for them. This extends the capabilities of JavaScript from only making websites more interactive to just about anything.


A linting coding tool that’s widely used in most NodeJS development. Meaning that it does a static code analysis, and finds patterns, errors, and lines that do not fit the conventional style guidelines. This adds extra checking that the code works before it’s being executed.

The tool comes with a default rules set, but you could change them whenever you want. Big names using ESLint include Facebook, PayPal and more. For web developers, this tool is essential since it helps fix problems even before they occur.

With an extensive contributing guide and documentation, and a big community and even sponsors enthusiastic in the development of this tool, it sure is a great option for you.

AngularJS advertises to provide huge data requirements and a scalable infrastructure that supports large-scale applications, such as that of Google’s.


Creating integrated 2D and 3D maps is a breeze with the maptalks.js library. It is a light, feature-packed library that is easy to understand and use. If you want to take up a mapping project, you can use MapTalks to manage and analyze spatial data. It was first developed to help the YUM! food chain select locations for Pizza Hut and KFC outlets in China. But today, it is used in several other contexts, such as in the diverse map-centric activities by government departments and enterprises.


One of NodeJS’ trending modular open-source projects. It offers immense value because it makes an efficient HTTP request, even when working with JavaScript, a server-side language, and out-of-browser. Express furthermore is a non-opinionated framework.

It’s helpful in accomplishing tasks related to speed and app security. Often associated with MEAN, meaning, MongoDB, Express, Angular, and NodeJS stack for building web apps. Some noteworthy features include:

  • Different extensions and plugins support
  • URL-based routing mechanism that uses HTTP methods
  • Seamless database integration

The tool has a very strong website with plenty of examples and the documentation is translated into various languages. The community additionally is very robust and ready to help. For NodeJS developers with experience, it’s a great choice to contribute.


jQuery is an open source library that makes client-side HTML scripting easier. Its motto is “Write less, do more”, and it does exactly that. It wraps the most common JavaScript tasks and wraps them into methods. This makes writing code easier and more productive. Estimates put jQuery as the highest used library in web pages.


If you are looking to make scroll-driven interactives, Scrollama gives you a simple interface to do just that. Scrollama is a modern JavaScript library for scroll telling that uses IntersectionObserver to handle and detect element positions. Scrollytelling is the art of visual storytelling on the web, which can often prove challenging to implement. But with a tool like Scrollama, you can deliver an impressive project with ease.
