Critical Traps

  • fs.readFileSync blocks entire server — use fs.promises.readFile
  • Unhandled rejection crashes Node 15+ — always .catch() or try/catch
  • process.env values are strings — "3000" not 3000, parseInt needed
  • JSON.parse throws on invalid — wrap in try/catch
  • require() cached — same object, mutations visible everywhere
  • Circular deps return incomplete export — restructure to avoid
  • Event listeners accumulate — removeListener or once()
  • async always returns Promise — even for plain return
  • pipeline() over .pipe() — handles errors and cleanup
  • No __dirname in ESM — use fileURLToPath(import.meta.url)
  • Buffer.from(string) — encoding matters, default UTF-8
