Restaurant App

Restaurant App is containerized polyglot microservices application which 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 etc. 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.

Mobile app developed by Xamarin.Forms and supports iOS and Android, here you can find how to develop cross-platform mobile apps using C#. The example shows how to develop beautiful user interfaces using Xamarin.Forms and how to manage your code with Clean Architecture on the mobile side and get a clean, maintainable, testable code.
