This sample illustrates the use of update-with-start to send Updates to a Workflow, starting the Workflow if it is not running yet ("lazy init"). The Workflow represents a Shopping Cart in an e-commerce application, and update-with-start is used to add items to the cart, receiving back the updated cart subtotal.
To run, first see the main README.md for prerequisites.
Then run the following from this directory:
poetry run python worker.py
Then, in another terminal:
poetry run python starter.py
This will start a worker to run your workflow and activities, then simulate a backend application receiving requests to add items to a shopping cart, before finalizing the order.
