/dev-server [start|stop|status]

Manage the Next.js development server on port 3000.

Arguments

  • •start (default) — Start the dev server if not already running
  • •stop — Stop the running dev server
  • •status — Check if the server is running

Instructions

For status or no argument default check:

  1. •Run lsof -ti:3000 to check if anything is listening on port 3000
  2. •If a PID is found, report: "Dev server is running (PID: <pid>)"
  3. •If no PID, report: "Dev server is not running"

For start:

  1. •First check if port 3000 is already in use with lsof -ti:3000
  2. •If already running, report it and do nothing
  3. •If not running, start the server with npm run dev in the background
  4. •Wait a few seconds, then verify it started by checking port 3000 again
  5. •Report the result

For stop:

  1. •Find the PID with lsof -ti:3000
  2. •If found, kill it with kill <pid>
  3. •Verify it stopped
  4. •If no server is running, report "No dev server to stop"

Notes

  • •The dev server runs on port 3000 by default
  • •Use npm run dev to start (runs next dev)
  • •The server should be started in the background so it doesn't block the terminal
