rat-stack's CAFE news rounds up the Cloudflare + Alchemy + Foldkit + Effect ecosystem:
- Maple migration: Maple moved 100+ pages (300k lines) off React onto Foldkit in about three days, using a validation harness to keep every interaction and animation identical.
- xstate 6.0 alpha: adds system-wide onEmitted; @xstate/effect keeps full Effect Causes on failures, adds a snapshot codec and an oxlint plugin.
- durable-object-migrator: rivet-dev's tool migrates Durable Object SQLite data to Postgres, files, or Rivet Actors without downtime, with a library, agent prompt, and Alchemy support.
- Foldkit Blocks and Effect Layers canary preview enables composing Blocks and passing the root ApplicationBlock to Program.make.
