Setting up Mongo store for session cookies

Lecture 308:- Setting up Mongo store for session cookies

To set up a MongoDB store for session cookies, we need to install the connect-mongo package, which is a MongoDB session store for Connect and Express. We can install it using npm:

arduinoCopy code

npm install connect-mongo

Once installed, we can require it in our app.js file and use it to configure our session store:

javascriptCopy code

const session = require('express-session'); const MongoStore = require('connect-mongo')(session); // ... app.use(session({  secret: 'mysecretkey',  resave: false,  saveUninitialized: false,  store: new MongoStore({ mongooseConnection: mongoose.connection }) }));

In the above code, we create a new MongoStore instance and pass it our Mongoose connection. Then we include it in our session configuration options using the store property. This will allow us to store our session data in MongoDB.

Now, all our session data will be stored in the sessions collection in our MongoDB database. We can verify this by connecting to the database and checking the collections:

javascriptCopy code

mongoose.connect('mongodb://localhost/myapp', { useNewUrlParser: true, useUnifiedTopology: true })  .then(() => {    console.log('Connected to database');    console.log('Collections:', mongoose.connection.db.listCollections());  })  .catch((error) => console.log(error));

This will print out a list of all the collections in our database, including the sessions collection.
