OAuth for ATProto Apps Part 2: Mobile Implementation - Lost in Inference
Part 2 of a 2-part series on implementing OAuth authentication for ATProto (Bluesky) applications.


here's my take on a minimal oauth browser client for atproto! no special API client class โ just use plain `fetch` to make requests and a service worker automatically handles authorization headers/token refreshes/dpop retries/etc. (very experimental, not tested in production, use at your own risk)
