Question 116890 in Mongodb Question posted in
The official documentation can be found here.

Mongodb – nodemon app crashed – waiting for file changes before starting. Can someone sort this out please

import express from 'express';

import bodyParser from 'body-parser';

import mongoose from 'mongoose';

import cors from 'cors';

const app = express();

app.use(bodyParser.json({limit: "30mb", extended: true}));

app.use(bodyParser.urlencoded({limit: "30mb", extended: true }));

app.use(cors());

const CONNECTION_URL = 'mongodb+srv://humoudmajid:[email protected]/?retryWrites=true&w=majority'

const PORT = process.env.PORT || 5000;

mongoose.connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true })

    .then(() => app.listen(PORT, () => console.loq(`Server running on port: ${PORT}`)))

    .catch((error) => console.log(error.message));

mongoose.set('useFindAndModify', false);

Im getting this error code.

/Users/humoudmajid/Desktop/Projects/libs/memories_project/server/node_modules/mongoose/lib/index.js:224
    throw new Error(``${key}` is an invalid option.`);
          ^

Error: `useFindAndModify` is an invalid option.

    It’s deprecated now. You don’t need mongoose.set('useFindAndModify', false);. Just use mongoose.connect(CONNECTION_URL).then(()=>{console.log('...')})

    Delete the line

    mongoose.set('useFindAndModify', false);

    useFindAndModify is deprecated and not necessary anymore.
