After configuring my ExpressJS & MongoDB client and running Nodemon, I consistently encounter the following warning:
"DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor."
I am unsure about the specific location in my server.js file where I should add this code.
To integrate this, make sure to include it in the section where you establish your connection with MongoDB.
For instance (with Mongoose)...
const mongoose = require("mongoose");
const { DATABASE } = process.env; // This is a unique mongodb connection string that changes based on the NODE environment
const options = {
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
useUnifiedTopology: true
};
mongoose.connect(DATABASE, options); // Establish connection with our mongo database
Take a look at my Fullstack boilerplate, which includes an example of connecting to a local MongoDB database. Feel free to use it as a guide if required.
In case you are utilizing the mongodb instead of mongoose, you just need to include the { useUnifiedTopology: true } in your MongoClient.connection options:
MongoClient.connect('mongodb://localhost:27017', { useUnifiedTopology: true })
.then(client => {
// do some operations
}).catch(error => {
// handle errors
})
This advice might be beneficial for you.
