TypeError: mongoose.connect is not a function?

Question

Mongoose

when i use require commonjs everything works

const { Schema, connect } = require("mongoose");

connect("mongodb://localhost:27017/usersdb", {
  useNewUrlParser: true
});

but when i use ES6 import i get error

import { connect } from "mongoose";

connect(
  "mongodb://localhost:27017/usersdb",
  {
    useNewUrlParser: true
  }
);

SyntaxError: Requested module > 'file: node_modules/mongoose/index > .js' does not provide an export named 'connect'
and if you write like this

import * as mongoose from "mongoose";

mongoose.connect("mongodb://localhost:27017/usersdb", {
  useNewUrlParser: true
});

TypeError: mongoose.connect is not a
package.json function

    "mongoose": "^5.7.8",
    "nodemon": "^1.19.4"
  }
}

I want to use es6 module. Is there a way to use es6 modules with mongoose without getting an error?

Answer 1

I faced the same issue.
If you are using mongoose in a browser environment like me. I use react and in one of the components I tried to do mongoose.connect ()
In this case, the mongoose object will not have a connect method.
It is necessary to move the connection code into a separate file that will be executed in the nodejs environment.
Then mongoose will have the connect method and everything will work.
