approval

Overview ¶

Command approval shows signals (human-in-the-loop) and the control API.

    go run ./examples/approval

The "expense" workflow submits a report and then durably waits — possibly for a long time, across restarts — for an external approve/reject decision delivered as a *signal*. This program plays the manager: it starts a workflow, checks its status (it's waiting), then sends the decision. A second run shows cancelling a workflow that's still waiting.
