Local Dev Server

When to Use

  • Starting/stopping dev server
  • "Address already in use" errors
  • Infinite loading spinner / broken pages after build
  • .next cache corruption (vendor-chunks ENOENT, 404 on static chunks)
  • Server crashes and needs restart
  • After major code changes or branch switches

Standard Start (Clean)

Always prefer a clean start to avoid stale cache issues:

# 1. Kill any existing process on port 3030
lsof -ti:3030 | xargs kill -9 2>/dev/null
