The GitHub Copilot SDK can be embedded in your own applications, not just Microsoft's products. A developer built IssueCrush, a React Native issue triage app, to prove it: swipeable GitHub issue cards with on-demand AI summaries powered by the same model behind Copilot Chat, running gpt-4.1 on the backend.
The architecture is the most instructive part of this piece. React Native cannot run Node.js packages, so the Copilot SDK must live server-side. The server spawns a single CopilotClient instance, manages the full lifecycle of start, createSession, sendAndWait, disconnect, and stop, and proxies requests from mobile clients. Credentials never touch the React Native bundle. The Copilot CLI must be installed on the server and reachable via PATH, authenticated either through copilot auth or a COPILOT_GITHUB_TOKEN environment variable. Skipping cleanup leaks resources, something the author confirmed after two hours of debugging.
The full article includes working TypeScript for the session lifecycle, the complete architecture diagram, and the graceful degradation pattern when the Copilot service is unavailable. If you are building any mobile or web app that needs server-proxied AI and want a concrete, debugged reference implementation, read it in full.
