The logic is the routes will be talking to our controllers and the controller talks to the repository and the repository talks to our model. Before we define our routes we need to configure multer for our image upload. Create a multer. This is where all uploaded images will be stored. Since all images goes to the files directory, We have to make that files folder.
To do this head over to the index. We now have to define the methods for this routes. To do that create add this to the controller. Create a routerHandler. Then register it in the index. Make sure to register this file after the mongoose instance.
We can now start working on our cart features. Just like we did for the products module we will define the model, routes, repostory and controller files. Here we create our first schema to hold the instance of our current product and the create the second file which will hold the array of items in our cart.
Basically we write two methods that will get all cart items in our database and add an item to the cart model. We can now define our module routes and then define the global routes. Add this to the routes. This is what we will be using in our Frontend Application for testing purposes. After implementing this,Push your work to git and add the Link in the comment section.
Lets Have some Fun? Now that our backend is ready we can now move on to our frontend. For frontend, i am going write that in 3 different frontend technologies Vue, Angular and React, will post link here soon. Your email address will not be published.

What if 15 people walk away, say never-mind, but never empty their cart? Those who pay should affect inventory.
Thus, in setting up your product tables, be sure to have two fields for tracking products: availability and quantity. They are related, but in the e-commerce sense they are not the same. Final Note: In a load balanced web server scenario Amazon Web Service users will probably agree , it is more likely that sessions will be handled by a database because it makes it easier to centralize the data.
How about both? When you read shopping cart data, check your session first. If it's there, you save a trip to the database if your session isn't backed by a database. When you write, write to session and persist to the database. That way, you get speedy reads and the user doesn't lose their cart when they close their browser. If your shopping cart software can make the most of abandoned carts send reminders that maybe they should come back and finsh the sale ect and flush them from database and does good database housecleaning then keep them in the database.
If it only allows a return user to continue with current cart items then keep them hashed in cookie. I often update cart data into database first and keep a cached version for read-only requests e. Cart data should be read optimized. And because of cart data is often small so I'd like to keep it for anonymous users for months, store it in cookies too.
