react-router fullstack vite server-actions migration

React Router v7 absorbs Remix, becomes fullstack framework

Remix's loader patterns, server actions, and form handling are now native React Router features; upgrade via import swap and feature flags.

May 15, 2026

Summary

Eliminates the psychological friction of 'migrating' for 7+ million React Router projects. Devs get automatic code splitting, optimistic UI, and server rendering without rewriting—just bumping to v7 with a Vite plugin.

Why it matters

Implementation verdict

Replaces Remix as a separate package; requires React Router v7 stable release (currently gathering feedback). For new projects, start with React Router v7 now. Existing Remix apps: wait for final release, then swap imports and enable feature flags. Worth trying in early releases if you need server rendering or form actions today.
