Hands-on guides to building and running backend services: Node.js and Bun runtimes, NestJS, REST and MCP APIs, performance and production patterns.
Backend & APIs
I upgraded a real NestJS 11 API to NestJS 12.1.3 with nest upgrade, fixed what broke (TypeScript 6, Jest and ESM, @Optional), and benchmarked v11 vs v12, Zod vs class-validator, Jest vs Vitest, ESLint vs oxlint, TypeScript 7 and Bun.
Backend & APIs
I ran the same Hono, Express and Postgres apps on Bun 1.4.3, Node.js 24 and Node.js 26, then measured throughput, memory, startup, TypeScript, installs, next build and native addons. Here is when Bun is worth switching to, and when Node 26 is enough.
