How to fix The default export is not a React component, and has been skipped in React

// ✅ Correct - Function component
export default function MyPage() {
  return <div>Hello World</div>;
}

// ✅ Correct - Arrow function component
const MyPage = () => {
  return <div>Hello World</div>;
};
export default MyPage;

// ❌ Wrong - Not a component
export default { title: 'My Page' };

// ❌ Wrong - Doesn't return JSX
export default function MyPage() {
  console.log('Not returning anything');
}

// ❌ Wrong - Returns undefined
export default function MyPage() {
  return;
}

// MyComponent.jsx
export const MY_CONSTANT = 'value';
export const myContext = createContext();

export default function MyComponent() {
  return <div>Component</div>;
}

// constants.js
export const MY_CONSTANT = 'value';

// context.js
export const myContext = createContext();

// MyComponent.jsx
import { MY_CONSTANT } from './constants';
import { myContext } from './context';

export default function MyComponent() {
  return <div>Component</div>;
}

// ❌ Wrong - May return undefined
function MyComponent({ show }) {
  if (show) {
    return <div>Content</div>;
  }
  // Missing return statement
}

// ✅ Correct - Always returns JSX
function MyComponent({ show }) {
  if (show) {
    return <div>Content</div>;
  }
  return null; // Explicitly return null
}

// ✅ Correct - Conditional rendering
function MyComponent({ show }) {
  return show ? <div>Content</div> : null;
}

// ❌ Wrong - Exporting data fetching function
export default async function getServerSideProps() {
  return { props: {} };
}

// ✅ Correct - Component as default, data fetching as named export
export default function MyPage({ data }) {
  return <div>{data}</div>;
}

export async function getServerSideProps() {
  return { props: { data: 'example' } };
}

// app/page.tsx
export default function Page() {
  return <div>Page content</div>;
}

// ❌ Wrong - Re-exporting a configuration object
import config from './config';
export default config;

// ❌ Wrong - Importing wrong entity
import { myUtility } from './utils';
export default myUtility;

// ✅ Correct - Importing and exporting component
import MyComponent from './MyComponent';
export default MyComponent;

// ✅ Correct - Direct component export
export { default } from './MyComponent';
