+# React Native (GraphQL)
+
+This repository illustrates how to use [Mock Service Worker](https://github.com/mswjs/msw) to mock a GraphQL server for development and testing in a React Native project.
+
+## Technologies
+
+- [**React Native**](https://reactnative.dev)
+- [React Testing Library](https://github.com/testing-library/react-testing-library) for testing assertions;
+
+## Getting started
+
+```bash
+$ git clone https://github.com/mswjs/examples.git
+$ cd examples
+$ yarn
+$ cd graphql-react-native-apollo
+```
+
+## Running locally
+
+```bash
+$ yarn start
+```
+
+### Android
+
+```bash
+$ yarn android
+```
+
+### iOS
+
+```bash
+$ yarn ios
+```
+
+## Tests
+
+```bash
+$ yarn test
+```
+
+## Key points
+
+- [`mocks/handlers.js`](mocks/handlers.js) describes request handlers to use.
+
+### React Native
+
+- [`mocks/native.js`](mocks/native.js) enables request interception in React Native runtime;
+- [`index.js`](index.js) conditionally enables mocking in `development` environment.
+
+### NodeJS
+
+- [`mocks/server.js`](mocks/server.js) enables requests interceptions in NodeJS (i.e. for tests with jest);
+- [`jest.setup.js`](jest.setup.js) configures test runner to use API mocking in tests.
