dbos-inc/dbos-transact-ts is a TypeScript durable workflow (durable workflow) library built on top of Postgres. A durable workflow is a flow that continues from the last completed step even when a run is cut short. The README explains that you register workflows and steps as ordinary functions, and the library checkpoints state in Postgres and automatically resumes from the last completed step after a failure. A checkpoint means saving progress in advance. The latest release is v5.3, and the given record contains no changelog for this release.
The point of this library is to offer durable queues, scheduling, notifications and workflow management together on Postgres, without a separate orchestrator or queue service. An orchestrator is a separate execution engine that runs workflows on your behalf and manages their order; here Postgres takes that role. The README describes this setup as a lightweight durable workflow library built on top of Postgres. The language is TypeScript and the license is MIT, and the repository, created in July 2023, has 1407 stars.
That said, the only evaluation left for this repository is a momentum score of 1.8 out of 10, and the other items are unrecorded. No performance figures and no adoption cases are given either. So at this stage, this library reads as a candidate worth trying for TypeScript teams that already run Postgres and want auto-resuming workflows without adding a separate execution engine.
