JavaScript library for building user interfaces. Declarative, component-based. Frontend only — runs in the browser, never on the server by itself.

Components return JSX (HTML-like syntax in JS). State changes trigger re-renders. The browser does all the work.

SPA (Single Page Application): React controls the entire page. Navigation happens client-side — no full page reloads.

Needs a bundler to ship (Vite, Webpack) or a framework to add backend (Next.js)

InfraPhysics uses React 19 + Vite 6. All content compiles at build time to static HTML/JSON. The browser loads React, which renders the UI. No backend — just static files on Cloudflare Pages. Including the Second Brain — 100% frontend, fieldnotes compiled to JSON, graph and search all in the browser.
