Abstract: Get hands-on in this talk where we’ll create a GitHub Copilot Extension from scratch.

We’ll use the Copilot Extensions SDK, and Hono.js, covering best practices like payload validation and progress notifications and error handling.

We’ll also go through how to set up a dev environment for debugging, including port forwarding to expose your extension during development as well as the Node.js debugger.

By the end, we’ll have a working Copilot extension that the audience can try out live.
