AI apps must call LLMs securely, stream tokens to the frontend in real time, and manage session state. This guide uses Next.js 16 App Router, Server Actions, and AI SDK to implement a clean, streamable AI chat page ready for production.
Technical trends, engineering practices, and independent development perspectives centered on Next.js and React.
Technical trends, engineering practices, and an independent developer perspective on TypeScript and React.
Technical trends and engineering practices around Next.js and React, from an independent developer's perspective.
Server Components power the App Router, but their boundary with Client Components is often misunderstood. This guide explains how RSC works, when to use 'use client', server-to-client data flow, caching, Suspense streaming, and common mistakes such as marking everything as client code or using browser APIs on the server.
Most React slowdowns come from unnecessary re-renders. Learn the right order: measure with Profiler, then optimize; use memo/useMemo/useCallback correctly; improve keys and lists, split state, use concurrent features, and avoid premature optimization.
Tailwind is fast for small projects but can become chaotic at scale through duplicated classes and drifting design tokens. This guide covers tokenized design-system configuration, component abstraction with React, @apply, and cva, class hygiene, Figma alignment, dark mode, and responsive design.
Core Web Vitals are more than SEO metrics; they quantify real user experience. This article explains what LCP, INP, and CLS measure, why they matter, how to measure them with Lighthouse, real-user data, and PSI, and how to improve images, fonts, JavaScript, layout stability, and interaction responsiveness.
Without the OWASP Top 10, Web applications are easy targets. This article explains XSS, SQL injection, CSRF, SSRF, insecure deserialization, and broken access control, including how they work, how modern frameworks defend against them, and the core habits of distrusting input, escaping output, and using parameterized queries.
State management is a perennial React topic, and too many choices can create confusion. Learn the right layer for useState, useReducer, Context, Zustand, and Redux; client vs. server state with React Query/SWR; and when Context or a global store is appropriate.
Still centering with float and margin? Modern CSS has moved on. This article covers the division of labor between Flexbox (1D) and Grid (2D), modern centering/equal-height/holy-grail patterns, Container Queries (component-level responsiveness), and new CSS capabilities (@layer/:has/logical properties)—so you write stronger layouts with less code.
Calling setState on every token off the network multiplies React commits. This article constrains only the frequency and freshness from event to commit, using per-frame coalescing, Event Timing, and LoAF to build release gates.
