Building Resilient TypeScript REST APIs with Node.js and PostgreSQL

A DEV Community post argues that backend slowdowns usually stem from inefficient queries, missing connection pooling, and weak TypeScript typing rather than hardware limits. It recommends moving beyond basic CRUD toward a production-grade architecture. The author highlights strict type safety, using TypeScript interfaces for request validation and database models to catch errors at compile time. The piece also advises analyzing query execution with EXPLAIN ANALYZE instead of adding indexes blindly. It closes by asking developers which stubborn bottleneck they have recently debugged in a Node.js REST API.
