Fix Convert javascript files to typescript with gitauto model

Original issue: #19

What is the feature

The feature involves converting existing JavaScript files in the repository to TypeScript.

Why we need the feature

Migrating to TypeScript provides several benefits:

Type Safety: Helps catch errors at compile time, reducing runtime errors.
Improved IDE Support: Better autocompletion, navigation, and refactoring capabilities.
Documentation: Types serve as a form of documentation, making the codebase easier to understand and maintain.
Scalability: Facilitates the development of large-scale applications by enforcing consistent type definitions.

How to implement and why

Install TypeScript and Necessary Dependencies:
- Add TypeScript and type definitions for Node and React.
- Update tsconfig.json to include necessary configurations.
Rename JavaScript Files to TypeScript:
- Change file extensions from .js to .ts or .tsx for React components.
Add Type Annotations:
- Define types for props, state, and other variables.
- Use interfaces and type aliases where appropriate.
Update ESLint Configuration:
- Modify .eslintrc.json to support TypeScript linting.
Refactor Code:
- Replace any types with specific types.
- Ensure all TypeScript-specific syntax is correctly implemented.
Test the Application:
- Run the application to ensure all functionalities work as expected.
- Fix any type errors or issues that arise during the migration.

File Changes:

pages/_app.js -> pages/_app.tsx
pages/index.js -> pages/index.tsx
theme/styles.js -> theme/styles.ts

Example Changes:

pages/_app.js:

// Before
function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
export default MyApp;

// After
import { AppProps } from 'next/app';

function MyApp({ Component, pageProps }: AppProps) {
return <Component {...pageProps} />;
}
export default MyApp;

pages/index.js:

// Before
const Home = () => {
return <div>Welcome to Next.js!</div>;
};
export default Home;

// After
const Home: React.FC = () => {
return <div>Welcome to Next.js!</div>;
};
export default Home;

theme/styles.js:

// Before
const styles = {
container: {
  padding: '20px',
},
};
export default styles;

// After
interface Styles {
container: React.CSSProperties;
}

const styles: Styles = {
container: {
  padding: '20px',
},
};
export default styles;

By following these steps, we ensure a smooth transition from JavaScript to TypeScript, enhancing the overall quality and maintainability of the codebase. """
