Adding Redis to your infrastructure stack just for session storage adds operational complexity, memory pressure, and a new failure mode. Here is a production-grade session store built on PostgreSQL with row-level locking, lazy cleanup, and session rotation that handles 10,000 concurrent users without breaking a sweat.
A no-nonsense benchmark and implementation guide for the three serious password hashing algorithms in Node.js, with production migration strategies, cost tuning, and hash-format portability.
Stop storing password hashes. Here is a working WebAuthn / passkey implementation for Node.js that replaces passwords with biometric or device-bound credentials using the FIDO2 standard, with server-side validation, credential storage in Postgres, and a minimal client implementation.
