Dev Start

Development Server Starter

Start development servers for projects with proper health checks and dependency management.

Arguments

• $ARGUMENTS: Project name or path (optional - uses current directory if not specified)

Known Projects Configuration

Execution Steps

1. Detect Project Type

Check for configuration files:

• pyproject.toml or requirements.txt → Python project
• package.json → Node.js project
• pnpm-lock.yaml → Use pnpm
• uv.lock → Use uv for Python

2. Check Dependencies

Python:

# If uv.lock exists
uv sync
# else
pip install -r requirements.txt

Node.js:

# Check package manager
if [ -f "pnpm-lock.yaml" ]; then
    pnpm install
elif [ -f "yarn.lock" ]; then
    yarn install
else
    npm install
fi

3. Check Port Availability

lsof -i :PORT

If port is in use, warn the user and offer to kill the process.

4. Start Server

Run the appropriate start command based on project detection.

FastAPI (Python):

cd ~/Projects/$PROJECT
uv run python server/app.py &
# or
uv run uvicorn app.main:app --reload --port 8000 &

Next.js/React:

cd ~/Projects/$PROJECT
npm run dev &
# or
pnpm dev &

5. Health Check

Wait for server to be ready:

# Poll health endpoint (max 30 seconds)
for i in {1..30}; do
    if curl -s http://localhost:PORT/health > /dev/null 2>&1; then
        echo "Server is ready!"
        break
    fi
    sleep 1
done

Multi-Service Mode

For full-stack development, start multiple services:

# Example: Start Erudition full stack
/dev-start eruditiontx-services-mvp  # Backend on 8000
/dev-start eruditiontx-client-mvp    # Frontend on 3000

Output Format

Starting: [project-name]
Directory: ~/Projects/[project]
Command: [start command]
Port: [port]

[Server output...]

Health check: PASSED
Server running at: http://localhost:[port]

Troubleshooting

If server fails to start:

1. Check if port is already in use
2. Verify environment variables (.env file exists)
3. Check dependencies are installed
4. Review error logs
