How To Contribute To Open Source Javascript Projects

Open source projects are incredibly beneficial to everyone. They bring like-minded people with talent together, they provide a means for individuals to collectively build something bigger than themselves, and they help push the web forward. Benefits of open source go beyond the programmer and extend to the users as well. Many of today’s most popular websites rely on open source software. For example, both Facebook and Gmail are powered by open source projects. The benefits of open source are many and most have never encountered one of them before….

React is the Facebook’s JavaScript library for building user interfaces.
Following are the distinctive features of React according to its official documentation:

  • Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
  • Component-Based: Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.
  • Learn Once, Write Anywhere: We don’t make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.


When you build website menus and webpages using only HTML5 and CSS, you’re limited to creating links that move the user from one static landing page to another — it’s JavaScript that allows for drop down, collapsible, and otherwise animated navigation features when you’re doing web development.

Animated navigation toggles are another ubiquitous part of the internet landscape that you’ll be able to crank out for clients and potential employers once you get the hang of the JavaScript programming language, even if you’re not a back end programmer. This JavaScript project sample by A. James Liptak(opens in a new tab) shows the kind of dynamic navigation features you’ll have access to once you’ve added JavaScript to your toolkit.

Tone.js is a Web Audio framework for creating interactive music in the browser.
The architecture of Tone.js aims to be familiar to both musicians and audio programmers looking to create web-based audio applications.

On the high-level, Tone offers common DAW (digital audio workstation) features like a global transport for scheduling events and prebuilt synths and effects. For signal-processing programmers (coming from languages like Max/MSP), Tone provides a wealth of high performance, low latency building blocks and DSP modules to build your own synthesizers, effects, and complex control signals.


Polymer is a JavaScript open source library for building applications using what are called “Web Components”. This provides the developer with the idea of reusable widgets or blocks on the web, facilitating interoperability of individual web elements. This idea is used in many complex projects such as YouTube and Google Earth.


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.


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.

Learn the basics

When working with GitHub, you should know how to use Git – one of the most popular version control tools (also known as revision control tools). Because developers constantly make changes to their code, they need a system that can manage those changes in a central repository. In this way, everyone involved in the development process can download a given piece of software, make changes, and submit updates.


A headless, open-source content management system, which is a backend-only system that functions with the use of RESTful APIs. The aim of this tool is to get and deliver content structurally across any device.

It provides plenty of features, which include an in-built email system, file upload, auto-generated documentation, and JSON Web Token authentication. The content structure furthermore is built via Strapi, which is very flexible. It lets you create and reuse content groups and customizable APIs.

Join the community

You can easily join an open source project by subscribing to the mailing list for that project. You can find mailing lists on official websites or on GitHub pages. After being accepted to the list, you can communicate with team members and get support if necessary. Thanks to the vibrant communities present in nearly every OSS project, you are likely to get quick replies to your questions.


If you are looking to make scroll-driven interactives, Scrollama gives you a simple interface to do just that.

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.


This project comprises individual sessions that demonstrate the creation of output with WebGL programming. You are free to use the components of the code for non-commercial usage, but don’t forget to observe the Creative Commons attribution if you copy-paste an entire session. Also, you will have to file an issue for consideration if you want to use it for commercial purposes.

All skills are welcomed

Even non-programmers can contribute to open source projects! Documentation is needed for all projects, and sometimes this is poorly written and maintained. Thus, you can help by writing, updating or even translating documentation. Also, your design skills might come in handy: every application needs an interface, after all. Finally, you can contribute by managing a community by replying to questions and guiding newcomers.


The article aims to help you contribute to open source projects used by millions of people across the globe. These projects are not only helping change lives but they are also making the world a better place through dedication, sharing and community spirit.
