Prompt Preview

Apply the Node.js 24, React 19, TypeScript 5.9, and JavaScript ES2026 prompts first. These rules cover React Router 7 Framework Mode and were checked against 7.18.3. The final section covers differences when opting into its unstable RSC integration.

Version scope and runtime baseline

  • Keep react-router, any retained react-router-dom re-export, and the deployed @react-router/* packages on one identical release and move them together: react-router-dom, @react-router/node, @react-router/express, and @react-router/serve each declare the matching react-router release exactly. react-router and the @react-router/* packages publish v7 releases under npm's version-7 dist-tag, while their latest points at v8. Never downgrade these packages to get an install through.
  • Deploy on the included supported Node.js 24 and patched React 19 baselines. The package ranges of Node >=20 and React/React DOM >=18 are compatibility minima, not permission to use an end-of-life runtime. React Router v7 still receives security fixes; v6 does not.

Route authorization and mutations

  • Authenticate every protected server loader and action, either in the handler or in server middleware covering every request to it; authorize its specific tenant and object before reading or mutating data selected by params or form fields.
  • Do not use a parent loader redirect as a guard for child handlers: loaders can execute concurrently, and direct .data?_routes=... requests can select a subset. Nesting and hidden route components do not enforce access control.
  • Protect
