React Native and Expo in monorepos. Use for Invalid hook call or duplicate react-native in a workspace app, Metro not resolving workspace packages, EAS failing only in the monorepo, hoisting and lockfile strategy.
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
# React Native in a monorepo ## First, delete the folklore Modern expo/metro-config configures Metro for monorepos automatically. If the repo carries a hand-written `metro.config.js` full of `watchFolders`, `nodeModulesPaths`, `extraNodeModules` or `disableHierarchicalLookup` copied from an old blog post, that config is now the most likely cause of the problem, not the fix. Strip it down to the default Expo config, run `npx expo start --clear` once, and re-test before debugging anything else. The problems that remain after that are real, and they are all below. ## Singletons, the actual monorepo disease react, react-native and the native-module packages must resolve to exactly one copy for the app. Two copies produce the classic signatures: - "Invalid hook call" with a perfectly valid component - "Tried to register two views with the same name" - A native module that works in one workspace app and crashes in another Diagnose with the package manager, not by staring at code: `npm ls react-native` (or `yarn why react-native`, `pnpm why react-native`) from the repo root. More than one resolved version, or the same version in two physical locations, confirms it. …

How to install
mdr add anilburcu/claude-code-react-native/monorepo-metro@sha256:9c61812b9ef5e4a8The 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.
