How can I create a simple Next.js API route that fetches data from my MongoDB collection?

here's how you can do it:

1// pages/api/items.js
2import { MongoClient } from 'mongodb';
3
4const uri = process.env.MONGODB_URI;
5let client;
6
7async function getClient() {
8  if (!client) {
9    client = await MongoClient.connect(uri, { useNewUrlParser: true, useUnifiedTopology: true });
10  }
11  return client;
12}
13
14export default async function handler(req, res) {
15  const dbClient = await getClient();
16  const db = dbClient.db('myDatabase');
17  const items = await db.collection('items').find({}).toArray();
18  res.status(200).json(items);
19}

Use process.env.MONGODB_URI for the connection string.
Call find({}).toArray() to get all documents and return as JSON.
