Hands-on guides to building production apps with Next.js and React: App Router, Server Components, caching, SEO, performance and UI patterns.
Next.js & React
A tested Sign-In with Ethereum flow for Next.js 16 with viem and iron-session: nonce, wallet signature and session, plus the cookie-nonce replay bug and the 1-second default verify I found while attacking it.
Next.js & React
TanStack Start 1.0 is stable, so I built the same store in Start and Next.js 16.4 and benchmarked both. Start served 2.9× to 8.6× more dynamic requests, shipped 20% less JS and built 3.9× faster. Next.js won on static pages.
Next.js & React
I compiled a Next.js 16.4 app with no compiler, the Babel React Compiler and the new Rust React Compiler, then counted re-renders in Chrome: 20,000 row renders dropped to 0, build cost, bundle size, lint rules and the memo() gap.
Next.js & React
A tested Better Auth 1.7 setup for Next.js 16.4 with Prisma 7 and PostgreSQL: route handler, server-action sign-in with nextCookies, proxy.ts checks, query counts per page load, the joins gotcha and Better Auth vs Clerk.
Next.js & React
Drizzle vs Prisma, benchmarked on PostgreSQL 17 across Drizzle 0.45, Drizzle 1.0 RC, Prisma 7 and Prisma 8 RC: query speed, the OFFSET trap, cold starts, install size, migrations and which to choose.
Next.js & React
React View Transitions are stable in React 19.3 and work in Next.js 16.4 with no config. Shared-element morphs, Suspense reveals, directional slides and addTransitionType, tested in Chrome, plus the back-button gap.
Next.js & React
Prisma 8 is a release candidate, yet npm install prisma already installs it. What changed from Prisma 7, what is missing, a tested side-by-side migration on PostgreSQL, two gotchas the docs skip, and whether to upgrade now.
Next.js & React
TypeScript 7 is the native Go compiler, latest on npm since July 2026. A tested upgrade guide: 5.2x faster builds on Hono, the removed tsconfig options, the typescript-eslint break, the TS 6 side-by-side setup and Next.js 16.4.
Next.js & React
The October 14, 2026 Next.js security update fixes two critical RCEs (use cache and SVG via sharp) and a Server Actions DoS. Check if you are affected, run a free checker script, and patch Next.js 15 and 16 on Docker or Coolify.
