Framework for the core domain development

This repository suggests solution for development of distributed systems with focus on the core domain development on the top of the .NET Core platform. Wiki

Main features

• DDD & Core domain

  In terms of DDD, core domain is the heart of your information system where magic happens. It is fundamental and critical part to the stakeholders that gives competitive advantage on the market and distinguish exact solution of the problem from the others. Taking care of infrastructure code and let focus on things that really matters in exact core domain is a key feature of this framework.

• Encourages best practices and patterns

  • Code first - code is the single source of truth and should be written in the way that allows to understand it clearly without any additional technical documentation;
  • Security - defense in depth with several decision points and declarative API;
  • Async out of the box - for scalability and, as a result, better throughput;
  • Dependency injection - intelligent composition of your source code in run-time based on assembly scanning and declarative API for managing code components and providing isolation even in single process deployment;
  • Composition and deployment freedom - microservices, monolith, modular monolith, single database or per-service database, choose any composition type what you want at any stage of your development combining different approaches;
  • Messaging - async messaging with message handler as unit of work and immutable message as input is the model for service communication for predictability and scalability;
  • Event sourcing - domain events are basic blocks of state changes through the system persisted in append only event store;
  • CQRS - read\write model separation for solving different problems with more appropriate tools;
  • Immutability - immutable data structures (messages, domain events) with static requirements and run-time validation;
  • Observability - logging, tracing and metrics collection with cross technology standard;

• Based on the latest, most popular and sustainable technologies

  • Dependency container - SimpleInjector
  • Message broker - RabbitMQ
  • Persistence - PostgreSql
  • Observability - OpenTelemetry
