Digital Menu Order System

How it works

• The waiter check-in the table for the clients -> the table status is set to active and is generated a secret token for the table and uploaded as QR code to S3
• Clients scan the QR code to get the secret token
• Only clients with the secret token of the table OR users with OWNER/WAITER roles can place orders
• Users with OWNER/COOK roles can update order status
• When the table is check-out the token is removed and the table status is set to inactive

Features

• When the client scan the table QR code
• Used Strategy and Factory patterns to allow an specific client to choose which storage service to upload images on the fly. (made just because I was curious in how to develop that, this is not a multi-tenant application)
• Upload QR code and Menu itens images to S3 by defualt, made decoupled to allow other storage services
• Generate QR code with secret token to allow the clients in the table to place orders

Technologies Used

• Backend: Spring Boot, Spring Security
• Authentication: Spring security with JSON Web Tokens (JWT) and roles
• Storage service: Amazon S3
• QR Code Generation: ZXing library

Setup

• Update application.properties with your database and S3 credentials.
• Create JWT_SECRET env variable

This project was made with the intention of learn the spring boot framework. It is not production ready.
