React Hooks, Server Components & React 19

React tutorials covering React 19 actions, Server Components, form libraries, state managers, and hooks pitfalls. Production code, real benchmarks.

This page collects 18 articles, newest first. Most of it is React 19 in production: what Server Components actually change about data fetching, why the compiler removes some memo calls and not others, and which form library holds up once validation gets messy. Where a benchmark is quoted, it was run on a real repo rather than a toy app, and the numbers include the runs that made the library look bad. A fair amount of space goes to the parts people get wrong in review, like putting a Suspense boundary at the route level and wondering why the whole page blanks. If you're arriving from class components, start with the hooks pitfalls pieces; the rest assumes you already know why the dependency array matters.

Everything else we've published is in the main archive.
