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
