Projecting React

I've been working on TanStack Start, and one friction has been nagging at me: React is big. Bundled through Vite, it lands at ~60 KB gzip on the client before a single line of app code runs. (The ~45 KB figure commonly cited is the CDN UMD build; modern ESM bundlers don't tree-shake down that far.) The rest of the TanStack toolchain (Router, Query, Store, Form, Virtual) is collectively a fraction

Reactがデカすぎる問題にAIで自作ライブラリ投下するのは流石TanStack。もう既存の重厚長大なライブラリは流行らないのかも

TanStack Start向けにReact公開APIを「core+8 toggleable」で投影し、約9.39KBで動作、React 19.2.3より2〜3×高速。
