Express 4 Sessions not persisting when restarting server
The default session store for express-session is MemoryStore, which as the name suggests, stores sessions in memory only. If you need persistence, there are many session stores available for Express. Some examples:
- Cookie store
- Redis store
- MongoDB store
- CouchDB store
- Riak store
- memcached store
- leveldb store
- MySQL store
- PostgreSQL store
- Firebase store

@mscdex answer is great but in case you are looking for code samples. Here is one with connect-mongo which should work fine if you mongodb and mongoose.
Install the package:
npm i connect-mongorequire the package:
const session = require('express-session'); // You must have express-sessions installedconst MongoStore = require('connect-mongo')(session)Now configure the session:
app.use( session({ secret: "mysecrets", resave: false, saveUninitialized: false, store: new MongoStore({ mongooseConnection: mongoose.connection, ttl: 14 * 24 * 60 * 60 }), }));Again this assumes you are using mongoose and have the connection configured.
If you did everything right, it should work just fine.
