Open source contribution: how to start contributing to TypeScript projects

Why open source is not scary, but beneficial

When I first decided to contribute to open source, I was shaking. It seemed like any commit of mine would be met by an army of seniors with flaming torches. But reality turned out to be different: the open source community is one of the friendliest places for developers. Especially when it comes to TypeScript projects.

In this article, I will tell you how to take the first step, not mess up, and enjoy the process. We'll cover everything: from finding a project to merging your first Pull Request. And yes, open source contribution is not just about altruism. It's about your portfolio, networking, and skill improvement.

Step 1: Find your project (and don't be afraid to make mistakes)

The main mistake beginners make is trying to contribute to React or the TypeScript compiler. It's like learning to swim by jumping straight into the ocean. Start small.

Where to find TypeScript projects

• GitHub Explore — filter by the TypeScript language to see fresh projects
• Good First Issue — a site that collects issues for beginners
• Up For Grabs — another aggregator of tasks for beginners
• Awesome for Beginners — a list of repositories labeled "for beginners"

Look for projects you actually use. Love lodash? Contribute to it. Use axios? Great, there's always room for improvement. Open source contribution becomes much more enjoyable when you understand what the code is for.

Step 2: Set up your environment and study the code

Let's say you've found a project. What's next? Don't rush to write code. First — reconnaissance.

Checklist before your first commit

• Read CONTRIBUTING.md — this is the project's bible. It tells you how to fork, branch, and commit.
• Look at the Code of Conduct — yes, it's boring, but it will save you from conflicts.
• Run the project locally — make sure the tests pass. If they don't, you've already found a bug!
• Read closed PRs — you'll understand how maintainers accept code.

Especially important for TypeScript projects: check the tsconfig.json settings. Sometimes strict typing rules can surprise you.

// Example of a typical tsconfig for an open source project{  "compilerOptions": {    "strict": true,    "noUncheckedIndexedAccess": true,    "exactOptionalPropertyTypes": true  }}

If your code doesn't compile with these settings — don't panic. This is normal for the first time. Just fix the types.

Step 3: Find your first task (and don't take on too much)

The most common question: "What exactly should I do?" Look for issues labeled good first issue, help wanted, or beginner. If there aren't any, look at low-priority bugs.

Example: a real task from open source

Imagine you found an issue: "Add support for an optional parameter in the date formatting function." Looks scary? Actually, it's not.

// Original code (simplified)export function formatDate(date: Date, format: string): string {  // ... implementation}

// Your task is to make format optionalexport function formatDate(date: Date, format?: string): string {  const defaultFormat = 'YYYY-MM-DD';  const activeFormat = format ?? defaultFormat;  // ... rest of the implementation}

See? Open source contribution often comes down to simple but important improvements. You don't need to rewrite the architecture right away.

Step 4: Create a Pull Request (and don't be afraid of criticism)

When the code is ready — create a PR. But first, check yourself:

• The code passes npm run lint and npm test
