DeprecationWarning: Mongoose: the `strictQuery` option will be switched back to `false` by default in Mongoose 7

Question

I am just making a database called Fruits from my app.js and connecting the database to MongoDB using Mongoose.

const mongoose = require("mongoose");

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

mongoose.set('strictQuery', false);

const fruitSchema = new mongoose.Schema({
    name: String,
    rating: Number,
    review: String
});

const Fruit = mongoose.model("Fruit", fruitSchema);

const fruit = new Fruit({
    name: "Apple",
    rating: 7,
    review: "Taste Good"
});

fruit.save();

Whenever I try node app.js, I am getting DeprecationWarning. Even though I tried using mongoose.set('strictQuery', true);, the same error continues as follows:

(node:15848) [MONGOOSE] DeprecationWarning: Mongoose: the `strictQuery` option w
ill be switched back to `false` by default in Mongoose 7. Use `mongoose.set('str
ictQuery', false);` if you want to prepare for this change. Or use `mongoose.set
('strictQuery', true);` to suppress this warning.
(Use `node --trace-deprecation ...` to show where the warning was created)
D:\Web Development\FruitsProject\node_modules\mongoose\lib\drivers\node-mongodb-
native\collection.js:158
          const err = new MongooseError(message);
                      ^

MongooseError: Operation `fruits.insertOne()` buffering timed out after 10000ms
    at Timeout.<anonymous> (D:\Web Development\FruitsProject\node_modules\mongoo
se\lib\drivers\node-mongodb-native\collection.js:158:23)
    at listOnTimeout (node:internal/timers:564:17)
    at process.processTimers (node:internal/timers:507:7)

Node.js v18.12.1

And then the second error also continues fruits.insertOne().

Because of this, my MongoDB database is not getting updated.

test> show dbs
admin    40.00 KiB
config  108.00 KiB
local    40.00 KiB
shopDB   72.00 KiB

I just want to fix this error. But I don't know where to fix this error. For the second part of the error, it seems like it is coming from the node_modules itself. How can I fix this error?

Answer 1

mongoose.set("strictQuery", false);

mongoose.connect(process.env.MONGO_URL);

OR

mongoose.set("strictQuery", false);
mongoose.connect(process.env.MONGO_URL, () => {
  console.log("Connected to MongoDB");
});

const connectDB = async () => {
    try {
        mongoose.set('strictQuery', false);
        await mongoose.connect(db, {
            useNewUrlParser: true,
            useUnifiedTopology: true,
        });
        console.log('MongoDB Connected...');
    } catch (err) {
        console.error(err.message);
        // make the process fail
        process.exit(1);
    }
