What are the best practices for using Next.js with TypeScript?

When using Next.js with TypeScript, it's important to follow best practices like defining types for props, using interfaces, and leveraging Next.js's built-in types.

Can you explain how to define types for props?

Sure! You can define types for props by creating an interface and then using it in your component. For example:

interface MyComponentProps {
  title: string;
  isActive: boolean;
}

const MyComponent: React.FC<MyComponentProps> = ({ title, isActive }) => {
  // component logic
};

What about using TypeScript with API routes in Next.js?

For API routes, you can define the request and response types. Here's an example:

import { NextApiRequest, NextApiResponse } from 'next';

export default function handler(req: NextApiRequest, res: NextApiResponse) {
  res.status(200).json({ message: 'Hello World' });
}

Are there any tools to help with TypeScript in Next.js?

Yes! Tools like ESLint and Prettier can help maintain code quality. Additionally, using TypeScript's strict mode can catch errors early.
