In this video, learn how to implement a shopping basket that stores its data in Redis.
- [Instructor] Every shopping application…needs a shopping cart.…So if users want to buy an item,…they will add it to the cart…and once they have all items together,…they can enter checkout process and buy.…So we need a way to store a list of items…and quantities for a user.…Of course, we could simply create the carts…directly on the session that's in array,…but this would mean that if the user logs in…from another device, which would imply a new session,…they would lose the cart.…So we need to persist the cart somewhere…and Redis is a good back end for that.…
So let's start implementing the service module for that.…So I open Server and there I open…BasketService.gs,…it's still empty and here we can now start…implementing all methods that we need…when dealing with our basket.…First, we have to create an export function.…Module.exports…and this function will now…accept a client as parameter…'cause…as I said before, we will maintain the Redis…connection in our…config object and…somehow we have to pass it in then…from our routes.…
