Critical Traps
fs.readFileSyncblocks entire server — usefs.promises.readFile- Unhandled rejection crashes Node 15+ — always
.catch()or try/catch process.envvalues are strings —"3000"not3000, parseInt neededJSON.parsethrows on invalid — wrap in try/catchrequire()cached — same object, mutations visible everywhere- Circular deps return incomplete export — restructure to avoid
- Event listeners accumulate —
removeListeneroronce() asyncalways returns Promise — even for plain returnpipeline()over.pipe()— handles errors and cleanup- No
__dirnamein ESM — usefileURLToPath(import.meta.url) Buffer.from(string)— encoding matters, default UTF-8
