Following this tutorial, but they do not use Typescript as me, and got stuck: [this video] Got this error Property 'mongoClient' does not exist on type '{ mongoClient: any; } | undefined'. // /pages/api/list.ts import { connectToDatabase } from '../../lib/connectToDatabase' import type { NextApiRequest, NextApiResponse } from 'next' export default async function handler( req: NextApiRequest, res: NextApiResponse ) { try { const { mongoClient } = await connectToDatabase() // <--- HERE const db = mongoClient.db('sample_restaurants') const collection = db.collection('restaurants') const results = await collection.find({}).project().toArray() res.status(200).json({ results }) } catch (e) {} } and //

I'm having an issue where my MongoDB database connects successfully in production, but fails to connect in localhost. Here's my setup: Backend (lib/mongodb.js): import { MongoClient } from 'mongodb'; if (!process.env.MONGODB_URI) { throw new Error('Invalid/Missing environment variable: "MONGODB_URI"'); } const uri = process.env.MONGODB_URI; const options = {}; let client; let clientPromise; if (process.env.NODE_ENV === "development") { // If `globalWithMongo` is not already defined, initialize it as an object if (typeof global.globalWithMongo === 'undefined') { global.globalWithMongo = {}; } // Use the `globalWithMongo` object to store the `_mongoClientPromise` if (!global.globalWithMongo._m

I owe you my gratitude. your code in the question resolved my issue in mongodb.js but here is a small code snippet which can help you temporarily. I changed my mongodb.js file to this content and it worked but although ill not recommend this as it solves the problems are surface level. import { MongoClient } from "mongodb"; if (!process.env.MONGODB_URI) { throw new Error('"Invalid/Missing environment variable:"MONGODB_URI"'); } const uri = process.env.MONGODB_URI; const options = {}; let client; let clientPromise; if (process.env.NODE_ENV === "development") { //In development mode , use a global variable so that the value // is preserved across module reloads caused by HMR(Hot Module Replace
