durable-workflows

A composable durable workflow library for JavaScript, actively inspired by Cloudflare Workflows, built on top of iso4.

Workflows run inside a sandbox and use a step-based API whose results are persisted, so they can be suspended, resumed on timers or external events, retried, or stopped. The persistence layer is pluggable — bring your own store — and the sandbox can be extended with your own global APIs and module imports.

🚧 Work in progress — nothing to see here yet.
