This sample has a Workflow that maintains state in a Map<string, number>. The state can be updated and read via a Signal and Query:

src/workflows.ts

The Client scripts are:

• src/start-workflow.ts
• src/query-workflow.ts
• src/signal-workflow.ts
• src/cancel-workflow.ts

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

Or run these to develop:

temporal server start-dev --db-filename temporal-db --log-format pretty
pnpm server.watch
pnpm external.watch
pnpm worker.watch
