Dev Server

Workflow

1. Check ports - Run scripts/check_ports.sh to scan common dev ports
2. Resolve conflicts:
   • Same project: Use --kill-if-same to kill without asking
   • Different project: Ask user before killing or use alternate port
3. Detect environment - Check for docker-compose.yml, monorepo structure, or package.json
4. Start server - Use detected package manager with --open flag; add --port <n> if needed

Port Script

scripts/check_ports.sh                   # Scan ports, show which project each belongs to
scripts/check_ports.sh 3000              # Check specific port with project info
scripts/check_ports.sh --find 3000       # Find first available port
scripts/check_ports.sh --kill-if-same 3000   # Kill only if same project (safe)
scripts/check_ports.sh --kill 3000       # Force kill (ask user first if different project)

The script detects project ownership by comparing the process's working directory to the current directory. "Same project" means the process was started from this directory or a parent/child of it.

Environment Detection

Docker projects: If docker-compose.yml exists with a web/app service, suggest docker compose up instead.

Monorepos: Check if current directory has package.json with dev script. If not, look for:

• apps/web/package.json or packages/app/package.json (Turborepo/Nx pattern)
• Root package.json with workspace dev script that delegates

Package manager: Detect from lockfile (bun.lockb → bun, pnpm-lock.yaml → pnpm, yarn.lock → yarn, otherwise npm).

Framework Notes

Most frameworks support --open and --port flags. Exceptions:

When --open doesn't work, fall back to open http://localhost:PORT after server starts.
