The Workflow

Use Claude Code to accelerate React Native mobile development: generate cross-platform components, configure navigation stacks, handle platform-specific code, and write tests. Covers both Expo and bare React Native workflows.

Expected time: 10 minutes setup Prerequisites: React Native CLI or Expo CLI, Claude Code installed, Node.js 18+

Setup

1. Initialize Project with Claude Code Context

# For Expo projects
npx create-expo-app@latest my-app --template blank-typescript
cd my-app

# For bare React Native
npx @react-native-community/cli init MyApp --template react-native-template-typescript
cd MyApp

2. Create CLAUDE.md for React Native

# Project: MyApp (React Native)

Expo SDK 52, React Native 0.76, TypeScript strict mode.

## Stack
- Navigation: React Navigation v7 (native stack)
- State: Zustand + React Query (TanStack Query v5)
- Styling: NativeWind v4 (Tailwind for RN)
- Forms: React Hook Form + Zod
- Testing: Jest + React Native Testing Library

## Conventions
- Components: src/components/ (one file per component)
- Screens: src/screens/ (screen components only)
- Hooks: src/hooks/ (custom hooks)
- Platform-specific: use .ios.tsx / .android.tsx suffixes
- All components must have displayName for debugging
- Use SafeAreaView wrapper on all screens
- Minimum touch target: 44x44 points

3. Verify

claude --print "List the screens in src/screens/ and describe the navigation structure"
# Expected output:
# Describes your app's screen files and navigation setup

Usage Example

Generate a complete authentication flow with Claude Code:

claude

> Create a login screen with:
> - Email and password fields with validation (React Hook Form + Zod)
> - "Remember me" toggle
> - Biometric authentication option (Face ID / fingerprint)
> - Loading state during authentication
> - Error display for invalid credentials
> - Use NativeWind for styling
> - Platform-specific biometric handling

Claude Code generates:

const loginSchema = z.object({
  email: z.string().email("Please enter a valid email"),
  password: z.string().min(8, "Password must be at least 8 characters"),

export function LoginScreen() {
  const [isLoading, setIsLoading] = useState(false);

    } finally {

Generate the matching test:

> Write a test for LoginScreen covering form validation, submission,
> and biometric fallback

// src/screens/__tests__/LoginScreen.test.tsx
import { render, fireEvent, waitFor } from "@testing-library/react-native";
import { LoginScreen } from "../LoginScreen";

jest.mock("expo-local-authentication", () => ({
  authenticateAsync: jest.fn().mockResolvedValue({ success: true }),
  hasHardwareAsync: jest.fn().mockResolvedValue(true),
  isEnrolledAsync: jest.fn().mockResolvedValue(true),
}));

describe("LoginScreen", () => {
  it("shows validation errors for empty fields", async () => {
    const { getByText } = render(<LoginScreen />);
    fireEvent.press(getByText("Log In"));

    await waitFor(() => {
      expect(getByText("Please enter a valid email")).toBeTruthy();
    });
  });

  it("calls login on valid submission", async () => {
    const { getByPlaceholderText, getByText } = render(<LoginScreen />);

    fireEvent.changeText(getByPlaceholderText("Email"), "[email protected]");
    fireEvent.changeText(getByPlaceholderText("Password"), "password123");
    fireEvent.press(getByText("Log In"));

    await waitFor(() => {
      expect(getByText("Log In")).toBeTruthy();
    });
  });
});

Common Issues

Why This Matters

React Native projects have significant boilerplate per screen. Claude Code generates a production-ready screen with validation, error handling, and tests in under 3 minutes instead of the typical 30-minute manual effort.
