Continue as New

This sample demonstrates the continueAsNew API. We still need to make these examples more relatable and realistic. If you are planning to write an infinitely long-running Workflow, please get in touch to validate the design and cutoff points.

Running this sample

  1. temporal server start-dev to start Temporal Server.
  2. npm install to install dependencies.
  3. npm run start.watch to start the Worker.
  4. In another shell, npm run workflow to run the Workflow.

In Temporal Web (localhost:8088), you will see 10 Workflows spun out as new Workflows with new event histories and Continuedasnew status:
