How do I handle errors in Next.js with GraphQL?

In Next.js, you can handle GraphQL errors by using try-catch blocks in your API routes or by checking the response from your GraphQL queries.

Can you give me an example of that?

Sure! In your API route, you can do something like this:

export default async function handler(req, res) {
  try {
    const data = await fetchGraphQLData();
    res.status(200).json(data);
  } catch (error) {
    res.status(500).json({ message: 'Internal Server Error', error: error.message });
  }
}

What about client-side error handling?

On the client side, you can use Apollo Client's error handling features. For example, you can use the onError link to catch errors globally.

Is there a way to show user-friendly error messages?

Yes! You can catch errors and display user-friendly messages in your UI, like 'Something went wrong, please try again later.'
