I am just learning mongodb-native driver for nodejs.
I connect like this.
var mongo=require("mongodb")
var serv=mongo.Server("localhost", 27017)
var dbase=mongo.Db("MyDatabase", serv)
And that works. But if I try to create a new database connection using the same server I get an error.
var dbase2=mongo.Db("MyDatabase2", serv)
"Error: A Server or ReplSet instance cannot be shared across multiple Db instances"
But it works if a make a new server connection first.
var serv2=mongo.Server("localhost", 27017)
var dbase2=mongo.Db("MyDatabase2", serv2)
So my question is why there are 2 connection functions, one for Server and one for Db, when it seems like they must always be used together?
Why doesn't it go like this.
var dbase=mongo.Db("localhost", 27017, "MyDatabase")
I want to make my own function that does this, but I wonder if there is some other reason they are separate.
Thanks.
