Code Repository for Temporal 102 (Ruby)

This repository provides code used for exercises and demonstrations included in the Ruby version of the Temporal 102 training course.

It's important to remember that the example code used in this course was designed to support learning a specific aspect of Temporal, not to serve as a ready-to-use template for implementing a production system.

For the exercises, make sure to run temporal server start-dev --ui-port 8080 --db-filename clusterdata.db in one terminal to start the Temporal server. For more details on this command, please refer to the Setting up a Local Development Environment chapter in the course. Note: If you're using the Codespaces environment to run this exercise, you can skip this step.
