Expo React Native JavaScript best practices for clean code, functional components, performance optimization, and Expo Router navigation.
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
# Expo React Native JavaScript Best Practices Guidelines for building high-quality Expo React Native applications with JavaScript, focusing on clean code, modularity, and performance. ## Code Style and Structure - **Clean, Readable Code**: Ensure your code is easy to read and understand. Use descriptive names for variables and functions. - **Functional Components**: Prefer functional components with hooks (useState, useEffect) over class components - **Component Modularity**: Break components into smaller, reusable pieces with single responsibility - **Feature-Based Organization**: Group related components, hooks, and styles into feature directories (e.g., user-profile, chat-screen) ## Naming Conventions - **Variables and Functions**: Use camelCase (e.g., `isFetchingData`, `handleUserInput`) - **Components**: Use PascalCase (e.g., `UserProfile`, `ChatScreen`) - **Directories**: Use lowercase hyphenated names (e.g., `user-profile`, `chat-screen`) ## JavaScript Usage - Minimize global variables to prevent unintended side effects - Leverage ES6+ features like arrow functions, destructuring, and template literals to write concise code …

How to install
mdr add mindrally/skills/expo-react-native-javascript-best-practices@sha256:1737ba5ad763c5d5The line at the top of this page pins the label git:20261008.7682ca7, 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.
