Build Your Own Code Generator

Learn how to build your own code generator from Event Models in 8 days. Each day should take you only 10-15 minutes. You'll learn invaluable lessons that took years to master.

8-Day Course

1️⃣

Day 1: Setup

Set the stage for the course. Clone the repository, install the Miro Toolkit, and prepare your environment.

 2️⃣

Day 2: Event Modeling Basics

Learn the basics of Event Modeling and play around with your first generated prototype.

 3️⃣

Day 3: JSON Structure

Analyze the JSON structure that serves as the basis for code generation and learn how to export from Miro.

 4️⃣

Day 4: First Generation

Start your first code generation and generate an event directly from the Event Model in Miro.

 5️⃣

Day 5: Custom Generators

Implement your first custom code generator fragments and generate Events and Commands.

 6️⃣

Day 6: Command Handlers

Generate command handlers from your Event Model configuration.

 7️⃣

Day 7: Result Events

Generate resulting Events and complete your command handler implementation.

 8️⃣

Day 8: Putting It to Work

Put your generated code to work and implement projections for Read Models.
