## 1. What is a monorepo in the context of React Native development?

**Answer**

A monorepo is an architecture where multiple projects or packages are stored in a single Git repository. In the React Native context, this enables code sharing between a mobile app, a web app (React Native Web), and utility packages. Benefits include centralized dependency management, atomic refactoring, and code consistency across platforms.

## 2. What is the main role of Yarn workspaces in a React Native monorepo?

**Answer**

Yarn workspaces enable managing multiple packages in a single repository with a single hoisted node_modules at the root. This reduces dependency duplication, enables automatic symlinking between local packages, and facilitates global scripts. In a React Native monorepo, this allows automatic linking of shared packages to both mobile and web applications.

## 3. How to configure a basic monorepo with Yarn workspaces for React Native?

**Answer**

The basic configuration requires a root package.json with the workspaces field defining package patterns. Typically, packages/* or apps/* is used for applications and packages/* for shared libraries. The private field must be set to true to prevent accidental publication of the root package. Metro bundler also requires configuration to resolve symlinks properly.
