This repository exists to teach Java development in VS Code with GitHub Copilot. The series takes this sample from a cloned folder to an app Copilot can call and test. Each chapter stands on its own, explains the concepts alongside the steps, and ends with a working result.
| # | Chapter | What you build | Video |
|---|---|---|---|
| 1 | Build and Run Your First Spring Boot App | Install the two extension packs, read the project structure, then build and run the app with Maven and the Spring Boot Dashboard. | Watch on YouTube |
| 2 | Debug and Inspect a Spring Boot Request | Pause a live request in the Java debugger, step across the class boundary, then check health and live memory. | Watch on YouTube |
| 3 | Expose Your Java Operations to Copilot with MCP | Publish the service operations as MCP tools and drive them from Copilot Chat. | Watch on YouTube |
| 4 | Let Copilot Test Your App with Playwright | Hand Copilot browser tools and have it test the UI end to end with Playwright. | Watch on YouTube |
