MongoStore.create({}) options 'client' and 'clientPromise' not compatible with Mongoose version 6

• Summary
  Mongoose has been updated to version 6. When using client or clientPromise in MongoStore.create({ }), sessions are no longer saved to database.

• Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

Can you provide any information that this is a bug in connect-mongo and not mongoose? I don't use mongoose (I really don't see the advantages over the core mongodb driver); and I (among many others) have been using connect-mongo reliably in production.

This will probably be solved with my PR that I'm trying to finish out

Hi. Any update? Everyone I know uses mongoose for MongoDB and when I do
store: MongoStore.create({ client: mongoose.connection, dbName: "sessions", }
it gives me an error of TypeError: con.db is not a function

4.6.0 released

It's still happening for me on 4.6.0

TypeError: con.db is not a function at ...\node_modules\connect-mongo\build\main\lib\MongoStore.js:126:18 at processTicksAndRejections (node:internal/process/task_queues:96:5)

This example demonstrates how it's done with Mongoose 6 https://github.com/jdesboeufs/connect-mongo/blob/master/example/mongoose.js . Though I prefer a bit simpler approach (one that's also closer to what was there with previous versions):

...
store: MongoStore.create({
    client: mongoose.connection.getClient(),
...

this works for me

const MongoStore = require('connect-mongo');

=================Main Code=============================

 const store = MongoStore.create({
    mongoUrl: dbUrl,
    secret: 'thisshouldbeabettersecret',
    touchAfter: 24 * 60 * 60
})

================= End Main Code=============================

store.on('error', function(e){
    console.log('Session Store Error', e)
})

const sessionConfig = {
    store,
    // change your default name
    name: 'session',
    secret: 'thisshouldbeabettersecret!', 
    resave: false, 
    saveUninitialized: true,
    cookie:{
        httpOnly: true,
        // don't use this on development it's break thing
        // secure: true,
        expires: Date.now() + 1000 * 60 * 60  * 24 * 7,
        maxAge: 1000 * 60 * 60  * 24 * 7
    }
}
app.use(session(sessionConfig))

@vishwajeetsinh-arham , your code (the mongoUrl option) tells connect-mongo to create and use its own connection to Mongo and will not reuse an existing one (like one created with Mongoose). It may not be a big deal in most cases but, being constrained by available memory, I prefer to keep the number of connections to a minimum.

Please using for mongo-store options { client : mongoose.connection.getClient() )
