OpenVeda Playbook: Node.js

Your guide to contributing to the core of the world's most popular JavaScript runtime.

1. The "Why": Mission & Impact

• The Mission: Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. It is a core technology of the modern web, powering the backend of countless websites and services.
• Your Impact: Your code can improve the performance, security, and features of the runtime itself. This is a deep, systems-level contribution that affects millions of developers.
• Why it's a Career Supercharger: "Node.js Core Contributor" is an elite title. It signals a deep mastery of JavaScript, an understanding of C++, and knowledge of low-level systems programming (event loops, streams, etc.). It is a direct path to top-tier backend and infrastructure engineering roles.

2. The "What": Tech Stack

• Core Languages: JavaScript and C++. The core libraries are written in JavaScript, but the underlying V8 engine and libuv event loop are written in C++.
• Key Tools: GitHub for everything, and a strong culture of collaboration through Working Groups.

3. The "How": Your Onboarding Journey

3.1: Join the Community

• Primary Channel (Slack): The OpenJS Foundation, which hosts Node.js, has a Slack workspace.
  • Link: Request an invite to the OpenJS Foundation Slack
• Your First Action: Join the #nodejs-dev and #nodejs-core channels.

3.2: The Setup Guide

• Official Guide: Compiling Node.js from source is your first major task.
  • Link: Guide to building Node.js from source

3.3: The Contribution Workflow

• Official Guide: The Node.js project has one of the most professional and well-documented contribution guides in the world. Read it carefully.
  • Link: Node.js Contribution Guide
• Key Point: All commits must be signed-off (using git commit -s), and you must follow their specific commit message format.

4. GSoC / LFX History & Focus Areas

• Mentorship Focus: Node.js participates in GSoC and LFX Mentorship. Projects are highly technical, focusing on areas like improving the performance of the HTTP parser, adding new APIs, enhancing security, and improving the test suite.
• What Mentors Look For: Deep technical curiosity and a lot of patience. The learning curve is very steep. Mentors want to see that you have successfully built Node.js from source and have made at least one small contribution (even a documentation fix) to prove you can navigate their rigorous process.

5. Key Repositories to Know

• The Core: github.com/nodejs/node
• Website & Docs: github.com/nodejs/nodejs.org (A great place to start!)
• Help & Examples: github.com/nodejs/help

6. Find Your First Task Right Now

• The Golden Link: The "good first issue" label is the official entry point.
  • Link: "good first issue" tag in nodejs/node
• Documentation: Fixing a typo or clarifying a sentence in the API documentation is a perfect and highly valued first PR.

7. The Unwritten Rules (Mentor Insights)

• Tests are Everything: Node.js has a massive and critical test suite. Any code change MUST be accompanied by new or updated tests. A PR without tests will be instantly rejected.
• Follow the Commit Format: Your commit message format is not a suggestion; it's a strict rule. Read their guide and follow it.
• Join a Working Group: The real work happens in the Working Groups (e.g., Streams WG, Security WG). Join their meetings, listen, and learn.
