Development Server Workflow for Bun React SSR

Understand the react-bun-ssr dev server workflow for Bun watch mode, rebuild signatures, transition endpoints, and reload semantics.

devwatchreloadtransitions

bun run dev is designed for correctness first. It rebuilds when the route signature changes and keeps client transitions working against fresh payloads.

What the dev server owns

  • file watching through Bun-friendly dev orchestration
  • route scanning and generated client entries
  • dev client bundles under /.rbssr/dev/client
  • internal endpoints like /__rbssr/transition
  • document reload notifications when the rebuild version changes

Rules

  • Dev responses stay non-cacheable.
  • Generated files are written under .rbssr/ so they do not pollute your source tree.
  • A file change should create one version bump, not a reload loop.

Next step

Use CLI as the command reference.
