Mongoose: Read on ReplicaSet

Question

I have a mongodb replica set from which I want to read data from primary and secondary db.

I have used this command to connect to the db:

mongoose.con

Answer 1

Following the documentation found on MongoDB website and on Mongoose web site, you can add this instruction for configuring the ReadPreference on Mongoose:

var opts = { replSet: {readPreference: 'ReadPreference.NEAREST'} };

mongoose.connect('mongodb://###:###@###:###/###', opts);

This has been tested using Mongoose version 3.8.9
