Food Delivery App

Overview of My Submission

This is a very simple food delivery app. It allows to search for food and then order and delivery it to your home.

The idea behind this was to build an event-driven distributed system. It contains 5 microservices which communicates with each other via events (most of the time).

Apart from that I wanted to try to implement a simple event sourcing system in which all business events are stored as a sequence of state-changing events.

In this project all these concepts are covered with Redis.

But this is not everything! It also uses other Redis modules, e.g. RedisJSON and Redis Search to show how easy it's to build a reliable system with Redis.

This is a very simple food delivery distributed system. It allows to search for food and then order them with a delivery.

The entire system is made of 5 microservices (1 React, 4 Java/Spring):

ui - React application, used by customers to place orders, manage them and track deliveries, url: http://localhost:80,
bff - backend for frontend service, used to provide REST endpoint for ui, url: http://localhost:8081/swagger-ui.html,
food - service that handles adding available meals to Redis, url: http://localhost:8084/swagger-ui.html,
ordering - core service for managing orders,
delivery - core service for managing deliveries.

Most of the communication is based on commands and events. E.g. in order to place an order a proper command…
