How do I configure Next.js for my project?

To configure Next.js, you need to set up a next.config.js file in your project root. What specific configurations are you looking for?

I want to enable image optimization and set up custom headers.

You can enable image optimization by using the next/image component. For custom headers, you can add them in the headers function in your next.config.js. Would you like an example?

Yes, please provide an example of the next.config.js file.

Here's a basic example:

module.exports = {
  images: {
    domains: ['example.com'],
  },
  async headers() {
    return [{
      source: '/(.*)',
      headers: [
        { key: 'X-Custom-Header', value: 'my-value' },
      ],
    }];
  },
};

This config enables image optimization and sets a custom header.
