How do I use async/await in Next.js with TypeScript?

You can use async/await in Next.js by defining your functions as async and using the await keyword for promises.

Can you show me a code example?

Sure! Here's a simple example:

import { GetServerSideProps } from 'next';

export const getServerSideProps: GetServerSideProps = async () => {
    const res = await fetch('https://api.example.com/data');
    const data = await res.json();
    return { props: { data } };
};

This fetches data on the server side using async/await.

What if I want to handle errors?

You can use try/catch blocks to handle errors. Here's an updated example:

export const getServerSideProps: GetServerSideProps = async () => {
    try {
        const res = await fetch('https://api.example.com/data');
        if (!res.ok) throw new Error('Network response was not ok');
        const data = await res.json();
        return { props: { data } };
    } catch (error) {
        console.error(error);
        return { props: { data: null } };
    }
};
