Step-by-step guides with working code. Ship something by the end.
Three CSS view transition patterns ship in production. Two don't. Real performance data, fallback strategies, and the line between demo and shipping code.
3 frontend tests worth writing with Vitest and Playwright, 4 to delete. A practical decision framework, not another tool comparison.
SSE or WebSocket? Three questions decide. A decision framework, side-by-side code, and the hybrid pattern — from a dev who shipped both.
3 patterns where CSS container queries beat media queries, a concrete migration path, and when media queries are still correct. Practical and opinionated.
REST API error handling best practices: build structured errors with RFC 9457, implemented in Express and Go — plus client-side consumption code.
AI assisted refactoring that won't break production. Three named patterns, a preflight checklist, and the trust-but-verify mindset that keeps code safe.
Model Context Protocol MCP: what it solves, how it compares to REST, and when to skip it. A developer's practical guide to the three primitives and production gotchas.
JWT vs session authentication: sessions for monoliths, JWT for microservices, hybrid when unsure. The decision framework most tutorials skip.
Agentic coding workflows: use multi-agent when tasks span isolated areas and take 2+ hours. For most work, one agent wins. A practical framework.
Not sure which API authentication pattern to use? This guide covers JWT vs sessions, security best practices, and when each approach actually makes sense.
