A deep technical guide to Next.js Route Handlers. Learn how to build production-grade APIs using web standards like Request and Response, handle streaming, implement middleware-like logic, and design scalable backend systems.
A deep technical exploration of backend middleware pipelines. Learn how composition patterns work, how the onion model structures request flow, how errors propagate across layers, and how modern frameworks implement middleware mechanics.
A practical deep dive into Node.js Streams and Web Streams in modern JavaScript applications. Learn how streaming improves memory efficiency, enables real-time data flow, powers SSR and AI responses, and changes how you design scalable systems.
The JavaScript event loop isn’t as simple as the diagrams suggest. This deep dive explores microtasks vs macrotasks, rendering phases, task prioritization, Node.js differences, and why your mental model of async execution is probably incomplete.
A practical architectural perspective on WebAssembly in the JavaScript ecosystem. Explore where WASM makes sense, performance trade-offs, tooling realities, integration patterns with React and Node.js, and when it’s overkill.
JavaScript concurrency isn’t true parallelism—and misunderstanding it leads to subtle performance bugs. This deep dive explores the event loop, microtasks vs macrotasks, async scheduling, Web Workers, and how concurrency really works in browsers and Node.js.
A practical deep dive into event-driven architecture patterns in Node.js. Explore event emitters, message brokers, pub/sub, event sourcing, CQRS, idempotency, and failure handling—plus real-world trade-offs in distributed systems.
