MongoParseError: options useCreateIndex, useFindAndModify are not supported

Question

I tried to run it and it said an error like the title. and this is my code:

const URI = process.env.MONGODB_URL;
mongoose.connect(URI, {
   useCreateIndex: true, 
   useFindAndModify: false, 
   useNewUrlParser: true, 
   useUnifiedTopology: true 
}, err => {
   if(err) throw err;
   console.log('Connected to MongoDB!!!')
})

I set the MONGODB_URL in .env :

MONGODB_URL = mongodb+srv://username:<password>@cluster0.accdl.mongodb.net/website?retryWrites=true&w=majority

How to fix it?

Solution 1

const URI = process.env.MONGODB_URL;
mongoose.connect(URI, { useUnifiedTopology: true } 
);
const connection = mongoose.connection;
connection.once('open', () => {
    console.log("MongoDB database connection established successfully");
} )

Solution 2

From the Mongoose 6.0 docs:

useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. Mongoose 6 always behaves as if useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and useFindAndModify is false. Please remove these options from your code.

Solution 3

Same problem was with me but if you remove useCreateIndex, useFindAndModify it will solve the problem just write :

const URI = process.env.MONGODB_URL;
mongoose.connect(URI, {
useNewUrlParser: true, 
useUnifiedTopology: true 
}, err => {
if(err) throw err;
console.log('Connected to MongoDB!!!')
});

It worked for me.

Solution 4

No More Deprecation Warning Options

useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. Mongoose 6 always behaves as if useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and useFindAndModify is false. Please remove these options from your code.

src --> https://mongoosejs.com/docs/migrating_to_6.html#no-more-deprecation-warning-options

// No longer necessary:
mongoose.set('useFindAndModify', false);
await mongoose.connect('mongodb://localhost:27017/test', {
  useNewUrlParser: true, // <-- no longer necessary
  useUnifiedTopology: true // <-- no longer necessary
});

Solution 5

I have the same issue. Instaead

mongoose.connect(URI, {
   useCreatendex: true, 
   useFindAndModify: false, 
   useNewUrlParser: true, 
   useUnifiedTopology: true 
}, err => {
   if(err) throw err;
   console.log('Connected to MongoDB!!!')
})

try this:

mongoose.connect(URI,
    err => {
        if(err) throw err;
        console.log('connected to MongoDB')
    });

This is the winning answer if you're coming from 4.x/5.x ➡️ 6.x. You also need to change the deprecated update, remove, and count methods to the new ones.
