learn React.js with Brian Holt
This is the lesson content and website source for Brian Holt's Frontend Masters course on React (v6 of the series), covering hooks, Redux, React Router, TypeScript integration, and testing. It's for developers working through the paid video course who want the accompanying written notes and code snippets, not a standalone library or tool.
The lesson breakdown is genuinely thorough — it covers class components through hooks, error boundaries, code splitting, and a full TypeScript pass (ts-*.md files) that a lot of React intros skip. Topics like portals, refs, and SSR get dedicated write-ups rather than a passing mention. The actual project code lives in a separate linked repo (citr-v6-project), keeping this one focused on the Gatsby site and markdown lessons.
Last pushed October 2022 — no updates for React 18.x refinements, let alone anything post-React-19 (no Server Components, no new hooks like useActionState). The content is locked behind a paywall course (frontendmasters.com) with CC-BY-NC-4.0 licensing, so you can read the free markdown here but the actual video instruction isn't included. There's no code in this repo to run or test against; it's a Gatsby static site wrapper around lesson text, so its value depends entirely on whether you're paying for the associated course.
