cmux Backend
Core rules
- Default backend TypeScript to Effect under
web/app/api/**,web/services/**, and backend scripts touching providers, databases, auth, rate limits, retries, timeouts, or telemetry. - Keep Next route handlers thin: parse the request, run one Effect program at the boundary, map typed errors to HTTP responses, treat unexpected defects separately.
- Plain TypeScript is for trivial data shapes, constants, config files, frontend React, and small glue where Effect would add ceremony without improving failure handling.
- Cloud VM backend logic stays in Vercel route handlers and Effect services backed by Postgres. Do not reintroduce Rivet or a raw actor protocol unless a later architecture doc explicitly changes the control plane.
- Postgres is the source of truth for VM lifecycle, active VM limits, idempotency, and usage events.
- Production and staging Cloud VM Postgres use PlanetScale PostgreSQL database
cmux-prodin organizationcmux. The runtime readsDATABASE_URLwithCMUX_DB_DRIVER=url; migration jobs use the protectedDATABASE_URLsecret. AWS credentials are not database credentials. - Run production/staging migrations with
bun run cloud-vm:migrate -- stagingfollowed by-- production; never from Vercel build or route startup. Local dev keeps theCMUX_PORT-derived Docker Postgres path frombun dev. - Cloud VM create pricing gates use Stack Auth team payment items when enabled.
Secrets
Cloud VM build, test, and local dev scripts read provider secrets from ~/.secrets/cmux.env: FREESTYLE_API_KEY and the R2 upload vars web/scripts/build-cloud-vm-images.ts needs when creating Freestyle snapshots.
bash
set -a
source ~/.secrets/cmux.env
set +a~/.secrets/cmuxterm-dev.env holds local Stack/web env and not the provider build keys. bun dev sources ~/.secrets/cmux.env first when present, then ~/.secrets/cmuxterm-dev.env, so cmuxterm-specific Stack settings override broader cmux secrets. The web dev loader still accepts the legacy ~/.secret/cmuxterm.env and ~/.secrets/cmuxterm.env paths while machines migrate.
