How do I use try-catch in async functions in Node.js?

How do I use try-catch in async functions in Node.js?

You can use try-catch blocks to handle errors in async functions. Here's a simple example:

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        return data;
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

What happens if I don't use try-catch?

If you don't use try-catch, any error thrown in the async function will result in a rejected promise, which can lead to unhandled promise rejections.

Can I use try-catch with multiple await calls?

Yes, you can use try-catch around multiple await calls. Just ensure that the entire block is wrapped in the try-catch to catch any errors from any of the awaits.

Is there a way to handle errors globally?

Yes, you can handle errors globally by using process.on('unhandledRejection') in Node.js to catch unhandled promise rejections.
