12:50 nanoid is throwing some error, which can be fixed by dunamically importing it -
async function generateNewShortURL(req, res) {
const body = req.body;
if (!body.url) {
return res.status(400).json({
error: "URL is required."
});
}
const { nanoid } = await import('nanoid');
const shortID = nanoid(8); // Generate the short ID
await URL.create({
shortId: shortID,
redirectURL: body.url,
visitHistory: [],
});
return res.json({ id: shortID });
};

[@hrithikjoshi4587]

Why is all the talk about a short id library and adding extra dependency for a small work. Use below function
function generateRandomString() {
const length = 8;
const chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
let result = '';
for (let i = 0; i < length; i++) {
result += chars.charAt(Math.floor(Math.random() * chars.length));
}
return result;
}

i copied and pasted your code but still getting error. What should i enter in the argument shortID inside await function?

res.redirect(url)
