Inventory

Simple application imitating an inventory from where you can make orders and payments¹.

Add products to the inventory 🔨. The frontend will make a call to the inventory service.
Make a payment on an item 💶. A message will be sent to Redis indicating that payment is made. 📨 This message will be caught by inventory service which will decrease the amount of the item correspondingly.
A complex scenario ❤️‍🔥 :

1. Create a payment on an inventory item.
2. Manage to delete the product in 5 seconds.

In the end the payment status should become 'refunded'.

Technologies used:

• Microservices architecture
• Event sourcing using Redis
• Database: RedisJSON
• Backend: Python FastAPI 🐍
• Frontend: ReactJS ⚛️
