Supabase auth and data access from React Native. Use for Apple or Google sign-in with Supabase, sessions dropping or not refreshing, auth deep links, RLS blocking mobile queries, requests hanging on slow networks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Supabase in a mobile app, the parts the docs gloss over ## Native sign-in beats browser redirects On mobile, prefer token-based native flows over web OAuth redirects. The user stays in the app, there is no browser handoff to break, and no deep-link dance: - **Apple**: the native Sign in with Apple sheet returns an identity token; pass it to `signInWithIdToken`. Hash the nonce (SHA-256) into the Apple request and pass the raw nonce to Supabase, and remember Apple only returns the user's name on the FIRST authorization, so persist it immediately or lose it. - **Google**: the native Google sign-in SDK returns an id token for `signInWithIdToken`. Check whether your chosen Google sign-in library supports a nonce parameter. Some do not, and then Supabase's nonce check fails; the "skip nonce check" switch in the Supabase dashboard exists for exactly that case. Prefer a nonce-capable library when starting fresh, and treat the skip switch as a documented tradeoff rather than a mystery setting. - **Email**: OTP codes (`signInWithOtp` then `verifyOtp`) avoid deep links entirely, which on mobile removes a whole class of "the magic link opened the wrong thing" support tickets. …

How to install
mdr add anilburcu/claude-code-react-native/supabase-mobile-auth@sha256:08f315a4a4d6ec2cThe line at the top of this page pins the label git:20260911.98ac3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
