mongo.isConnected alternative for node driver v4+

Question

Is there any alternative for the deprecated MongoClient.isConnected in the native Node JS MongoDB driver?

I read somewhere that one can handle the check via callbacks, which one can pass as parameters in the .connect Method (See the docs.) However, I wasn't able to successfully do that.

Answer 1

You can connect to MongoDB with the mongoose.connect() method.

mongoose.connect('mongodb://localhost:27017/myapp'); 

Install Mongoose from the command line using npm:

$ npm install mongoose --save

Refer to my MongoDB + Node example:
