postrust-worker

Postrust's REST API in a Cloudflare Worker, reaching PostgreSQL through Hyperdrive.

• The request pipeline is postrust-engine, the same one the server runs. The database driver speaks the PostgreSQL wire protocol over a Workers socket and is tested to answer exactly as the server's does.
• Every request runs in a transaction that takes on the token's role and claims, so row-level security applies as it does on the server.
• The schema cache is kept in Workers KV. It is refreshed by a Cron Trigger, by an authenticated POST /_/reload, or when the KV copy expires after PGRST_WORKER_SCHEMA_TTL.
• REST only, served at the root as PostgREST serves it. There is no GraphQL and no LISTEN/NOTIFY.

Setup, configuration, measured costs and limits: docs/workers.md. The crate is built with worker-build for wasm32-unknown-unknown; for any other target it is only its configuration logic, there to be unit-tested.

This crate is on its own 0.x line and makes no stability promise yet. See docs/stability.md.
