For those who want to the latest version of connect-mongo, the new syntax involves removing the parameter session from the require call and not using new any more but a method .create.
Here is what the documentation recommends:
const session = require('express-session');
const MongoStore = require('connect-mongo');
app.use(session({
secret: 'foo',
store: MongoStore.create(options)
}));
Basic usage would be:
app.use(session({
store: MongoStore.create({ mongoUrl: 'mongodb://localhost/test-app' })
}));
I had a similar issue while working on replit. My solution was to downgrade connect-mongo's version from 4 to 3.
npm uninstall connect-mongo
npm i connect-mongo@3
From this user's post:
const session=require("express-session");
const MongoStore=require("connect-mongo");
//*****************
app.use(session({
secret:"secret",
cookie:{maxAge:60000},
resave:false,
saveUninitialized:false,
store:MongoStore.create({mongoUrl:process.env.MONGO_URI}),
