// Example of a React functional component snippet using the ES7+ React/Redux/React-Native snippets extension
import React from 'react';

const MyComponent = ({ prop1, prop2 }) => {
  const [state, setState] = React.useState(initialValue);

  const handleClick = () => {
    // Functionality here
  };

  return (
    <div>
      {/* Component JSX */}
    </div>
  );
};

export default MyComponent;

When combined, ESLint and Prettier provide a powerful combination of code formatting and error detection, helping maintain code quality throughout your development process. Prettier ensures consistent code style across your React project, automatically formatting your code according to predefined rules, which eliminates debates over code style and ensures readability.

// Example of a React component structure with Prettier formatting
import React, { useState, useEffect } from 'react';

const UserProfile = ({ userId }) => {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchUser = async () => {
      try {
        const response = await fetch(`/api/users/${userId}`);
        if (!response.ok) throw new Error('User not found');
        const userData = await response.json();
        setUser(userData);
      } catch (err) {
        setError(err.message);
      } finally {
        setLoading(false);
      }
    };

    fetchUser();
  }, [userId]);

  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  if (!user) return <div>No user data available</div>;

  return (
    <div className="user-profile">
      <h2>{user.name}</h2>
      <p>Email: {user.email}</p>
      <p>Joined: {new Date(user.createdAt).toLocaleDateString()}</p>
    </div>
  );
};

export default UserProfile;

import MyComponent from './MyComponent';

test('renders component with correct text', () => {
  render(<MyComponent />);
  
  const element = screen.getByText('Expected Text');
  expect(element).toBeInTheDocument();
});

test('handles user interaction correctly', async () => {
  render(<MyComponent />);
  
  const button = screen.getByRole('button');
  await userEvent.click(button);
  
  expect(screen.getByText('Updated Text')).toBeInTheDocument();
});

// Example of a React component with testing setup
import React from 'react';
import { render, screen, fireEvent } from '@testing-library/react';
import '@testing-library/jest-dom';
import Counter from './Counter';

describe('Counter Component', () => {
  test('renders initial count of 0', () => {
    render(<Counter />);
    expect(screen.getByText(/Count: 0/i)).toBeInTheDocument();
  });

  test('increments count when increment button is clicked', () => {
    render(<Counter />);
    const incrementButton = screen.getByRole('button', { name: /increment/i });
    fireEvent.click(incrementButton);
    expect(screen.getByText(/Count: 1/i)).toBeInTheDocument();
  });

  test('decrements count when decrement button is clicked', () => {
    render(<Counter />);
    const decrementButton = screen.getByRole('button', { name: /decrement/i });
    fireEvent.click(decrementButton);
    expect(screen.getByText(/Count: -1/i)).toBeInTheDocument();
  });
});
