Upgrading from express 3.x to express 4.x - Mongo session store

Question

I'm migrating from express 3.x to express 4.x

I'm having issues finding a mongo session store which works with the new session middleware.

Previously:

express 3.x had connect as a dependency, which in turn came with bundled session middleware.

In order to persist sessions in a mongo database, the de-facto middleware was connect-mongo.

New world order:

Now with express 4.x, connect is no longer a dependency.

As such, pretty much all the previously bundled middleware has been factored out into separate middleware, such as session listed above.

session takes a store, but since connect-mongo depends on connect, is is not compatible with express 4.x.

Question:

I cannot find information on which mongo session store to use when migrating to express 4.x. Any suggestions?

Answer 1

connect-mongo still works in express 4.x, however, you now pass in session instead of express

Express 3.x:

var express = require('express');
var mongoStore = require('connect-mongo')(express); // note parameter = express

Express 4.x:

var session = require('express-session');
var mongoStore = require('connect-mongo')(session); // note parameter = session

NPM:

Unfortunately, at the time of writing, the latest version of connect-mongo has not been deployed to npm.

EDIT: The latest version of connect-mongo has been deployed to npm

You can either download the latest version direct from github

or a workaround is to create a temporary object:

{
    session: session
}

and pass this to mongo-connect:

var mongoStore = require('connect-mongo')({session: session});
