I am developing a SaaS application with multiple users. So I need to use appropriate database according to requesting user. Below is my basic database connection.

mongoose.connect(databaseLink, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useFindAndModify: false,
    useCreateIndex: true
})

We can use createConnection instead of connect to connect to multiple database. But for that I need to specify separate models. Here I need to share same model for each databases.

Edit

You can assume that required database name will be stored in req.dbName object. So when a user make a request from client1, req.dbName will equals to client1 and I need to use client1 database for that particular request.

you can simply make an object and store all connection strings there and as per the need you can use the connection string

var connetion_string = { "user":"mongodb://localhost:27017/usercollection", "marks":"mongodb://localhost:27017/markscollection"

}
