Error: The function `mongodb.connect` is not recognized

I encountered some errors in my project using Express.js and despite my attempts to fix them, I couldn't locate the source of the issue.

Below is a snippet of my code:

const mongodb = require("mongodb");
const dotenv = require("dotenv").config();

mongodb.connect(
  process.env.CONNECTION,
  { useNewUrlParser: true, useUnifiedTopology: true },
  function (err, client) {
    if (err) {
      console.log(err);
    } else {
      module.exports = client;
      const app = require("./app");
      app.listen(process.env.PORT, function () {
        console.log("connected");
      });
    }
  }
);

The error message I'm receiving is as follows:

Users/ismailtaibi/Documents/GitHub/worketplace-web/db.js:4 mongodb.connect( ^

TypeError: mongodb.connect is not a function at Object. (/Users/ismailtaibi/Documents/GitHub/worketplace-web/db.js:4:9) at Module._compile (internal/modules/cjs/loader.js:1072:14) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1101:10) at Module.load (internal/modules/cjs/loader.js:937:32) at Function.Module._load (internal/modules/cjs/loader.js:778:12) at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:76:12) at internal/main/run_main_module.js:17:47

Answer №1

If you're looking for different ways to connect, consider the following options.

const { MongoClient } = require('mongodb');

const uri = "mongodb+srv://<username>:<password>@<your-cluster-url>/test?retryWrites=true&w=majority";
const client = new MongoClient(uri);
try {
    await client.connect();
    await listDatabases(client);
} catch (e) {
    console.error(e);
}

Alternatively, you can use:

var MongoClient = require('mongodb').MongoClient;

MongoClient.connect("mongodb://localhost:27017/mymondb", function (err, db) {
  if(err) throw err;
  console.log('mongodb is running!');
  db.close();
});

Or, opt for the mongoose package:

const express = require('express')
const mongoose = require('mongoose')
const app = express()

mongoose.connect('mongodb://localhost/db1', {
    useNewUrlParser: true, useUnifiedTopology: true
})

app.set('view engine', 'ejs')
app.use(express.urlencoded({ extended:false }))

app.listen(process.env.PORT || 5000);
