Handling Errors

To handle errors effectively in Next.js, you can use the following methods:

1. Fetching Data with Error Handling

async function fetchData(url) {
    try {
        const response = await fetch(url);
        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }
        const data = await response.json();
        return data;
    } catch (error) {
        console.error("Fetch Error: ", error);
        return null; // Handle error accordingly
    }
}
        

2. Handling API Routes

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