Restaurant App

Restaurant App is containerized polyglot microservices application that contains projects based on .NET Core, Golang, Java, Xamarin, React, Angular and etc. The project demonstrates how to develop small microservices for larger applications using containers, orchestration, service discovery, gateway, and best practices. You are always welcome to improve code quality and contribute it, if you have any questions or issues don't hesitate to ask in our gitter chat.

To getting started, simply fork this repository. Please refer to CONTRIBUTING.md for contribution guidelines.

Motivation

Developing independently deployable and scalable micro-services
Developing cross-platform beautiful mobile apps using Xamarin.Forms
Configuring CI/CD pipelines using Gitlab CI, Azure DevOps, automated deployments using k8s, Helm, Docker
Using modern technologies such as GraphQL, gRPC, Apache Kafka, Serverless, Service meshes
Writing clean, maintainable and fully testable code, Unit Testing, Integration Testing and Mocking practices
Using SOLID Design Principles
Using Design Patterns and Best practices in different programming languages

Architecture overview

The architecture proposes a micro-service oriented architecture implementation with multiple autonomous micro-services (each one owning its own data/db and programming language) and using REST/HTTP as the communication protocol between the client apps, and gRPC for the backend communication in order to support data update propagation across multiple services.
