OpenSource Scout

Discover the best open-source repositories to contribute to based on your programming language, framework, skill level, and contribution goals.

OpenSource Scout is a developer-focused platform that helps contributors find high-quality GitHub repositories with active communities, beginner-friendly issues, healthy maintenance activity, and meaningful contribution opportunities.

Vision

The goal of OpenSource Scout is to eliminate the frustration of finding the right open-source project.

Instead of manually searching through thousands of repositories, developers can instantly discover repositories that match their skills, interests, and learning objectives.

Installation

1. Clone Repository

git clone https://github.com/KrrishSR4/OpenSourceScout.git
cd OpenSourceScout

2. Run with Docker Compose (Recommended)

Start the entire stack including Frontend, Backend, and Redis with a single command:

# Provide environment variables in your environment or a .env file
export DATABASE_URL="postgresql://user:pass@host:port/db"
export GITHUB_TOKEN="your_github_token"

docker compose -f docker/docker-compose.yml up --build

3. Run Manually (Local Development)

Setup Backend

cd server
npm install

# Configure environment variables in server/.env:
# DATABASE_URL="postgresql://user:pass@host:port/db"
# REDIS_URL="redis://localhost:6379"
# GITHUB_TOKEN="your_github_token"

# Sync Prisma database schema & generate client
npx prisma db push
npx prisma generate

# Start Express Dev Server
npm run dev

Setup Frontend

cd ../client
npm install

# Start Vite React Dev Server
npm run dev

    style D2 fill:#A569BD,color:#fff,stroke:none
    style D3 fill:#A569BD,color:#fff,stroke:none

Environment Setup

# CORRECT - Store token in .env (never commit this file)
VITE_GITHUB_TOKEN=your_token_here

# WRONG - Never hardcode tokens in source files
const token = "ghp_xxxxxxxxxxxx"

Always add .env to your .gitignore file.
