Web Vitals & Lighthouse 100: Practical Optimization Guide 2026
Achieving Lighthouse 100 on a real-world production Next.js app — not a blank page. Covers LCP, INP (replaced FID in 2024), CLS, TTFB, font optimization, image optimization, JS bundle analysis, and CSS critical path — with specific code changes.
OWASP Top 10 2025: Web Application Security Guide with Real Attack Examples
The OWASP Top 10 2025 lists the most critical web application security risks. This is not theory — each vulnerability includes a real attack example, how it works in your Node.js/React codebase, and the concrete fix.
Node.js vs Bun vs Deno in 2026: Runtime Comparison with Real Benchmarks
Bun 1.x is production-stable. Deno 2.0 supports npm packages. Node.js 22 has native TypeScript. The runtime landscape changed. Here's what the numbers actually show and when each runtime makes sense for real projects.
Clean Architecture in Node.js: A Practical Guide Without the Academic Fluff
Clean Architecture sounds great in theory. In practice, most implementations add complexity without benefit. This guide shows the pattern that actually works in Node.js — dependency inversion, use cases, and repository pattern with real, runnable code.
Supabase vs Firebase vs PocketBase 2026: Real Comparison for Production Apps
Choosing a backend-as-a-service in 2026: Supabase (PostgreSQL + open-source), Firebase (Google, mature ecosystem), or PocketBase (single binary, self-hosted). Real benchmarks, pricing at scale, and when each one breaks.
PostgreSQL EXPLAIN ANALYZE: Reading Query Plans Like a Senior DBA
Stop guessing why your queries are slow. Learn to read PostgreSQL query plans at a level where you can actually fix problems — seq scans, join strategies, row estimate disasters, and the N+1 you didn't know was hiding in your ORM output.
tRPC + Zod: End-to-End Type Safety Without Code Generation
tRPC eliminates the REST+OpenAPI codegen ceremony by making your server the source of truth for types. Here's a complete, production-realistic implementation — auth middleware, CRUD procedures, React Query integration, and the edge cases nobody mentions.
Redis Data Structures in Production: Beyond SET and GET
Most teams use Redis as a glorified hash map. This guide covers the data structures that solve real production problems — sorted sets for leaderboards, streams for durable event queues, HyperLogLog for UV counting at scale, and Lua scripts for atomic operations you can't otherwise do safely.
Vibe Coding in 2026: How AI Tools Are Changing Software Development Forever
Andrej Karpathy coined the term in 2025. By 2026, 'vibe coding'—describing what you want and letting AI write the code—is reshaping how teams build software. Here's what actually changed, what works, and what doesn't.
