The 2026 reference guide I wish I'd had when I started: from junior to expert, everything you actually need to know to run a production-grade Node.js API. Hybrid caching (NodeCache + Redis), Prisma/PostgreSQL deep dives, compression and payload strategy, profiling, clustering, security, reverse proxy, CDN, real field stories and mistakes I personally paid for. Results on my own projects: latency cut by 5x, costs cut by 3x, unlimited scalability. Even starting from zero, you'll finish this article at expert level.
