This is a typical system configuration of express and mongodb.
The first piece of code uses ‘connect-mongodb’ to connect to mongodb and store session settings.
The second piece of code is to obtain user login information (user) and other operations.

Refer to connect-mongodb for details: https://www.npmjs.com/package...
