Is Equinox Project production-ready?

While it demonstrates production-like patterns, the disclaimer explicitly warns against using it directly in production without modifications. It's best as a learning foundation or reference for building custom solutions.

How to add a new feature to Equinox Project?

Follow the layered architecture: define domain entities in the Domain layer, implement commands/queries in Application with NetDevPack.SimpleMediator, add infrastructure in Infrastructure, and update UI layers. The separation of concerns guides this process.

Equinox Project vs Microsoft Clean Architecture template: which is better?

Equinox Project offers more advanced features like DDD, CQRS, and Event Sourcing, while Microsoft's template is simpler and focuses on Clean Architecture basics. Choose Equinox for complex enterprise needs; use the template for straightforward applications.

Can I use Equinox with a frontend like React or Angular?

Yes, the WebAPI layer with JWT authentication is designed to work with any frontend framework. You can build SPAs that consume the APIs, and Swagger UI helps with testing endpoints.

What are the performance costs of Event Sourcing in Equinox?

Event Sourcing ensures data integrity but can introduce latency in read operations due to event replay. Equinox uses immediate consistency CQRS, so consider this trade-off for high-throughput systems where performance is critical.

How to deploy Equinox Project to Azure or Docker?

The project is ASP.NET Core-based and can be deployed to Azure (as shown in the demo), Docker containers, or other hosts. Update database connections from SQLite to a production DB like SQL Server and configure environment variables for security.

What is EquinoxProject?

Equinox Project is an open-source .NET Core reference application that demonstrates how to build modern web applications using Clean Architecture, Domain-Driven Design (DDD), CQRS, and Event Sourcing. It provides a production-ready foundation with ASP.NET 9.0, JWT authentication, and Entity Framework Core, serving as a comprehensive learning resource for enterprise development patterns. The project solves the problem of understanding and implementing complex architectural concepts in a practical, maintainable way.

Target Audience

.NET developers and architects looking to learn or implement Clean Architecture, DDD, CQRS, and Event Sourcing in real-world applications. It's ideal for teams building scalable enterprise systems who need a reference for best practices and modern .NET tooling.

Value Proposition

Developers choose Equinox Project because it offers a fully implemented, up-to-date reference application with the latest .NET technologies and architectural patterns, replacing heavy dependencies like AutoMapper and MediatR with lightweight alternatives. Its clear separation of concerns, built-in testing, and automatic setup make it an excellent foundation for learning and building production-ready applications without over-engineering.

Overview

Web Application ASP.NET 9 using Clean Architecture, DDD, CQRS, Event Sourcing and a lot of good practices

Use Cases

Best For

Learning Clean Architecture and Domain-Driven Design in .NET
Building enterprise web applications with ASP.NET Core and CQRS
Implementing Event Sourcing for data integrity in .NET systems
Setting up JWT authentication and WebAPI services in ASP.NET
Creating reference architectures for team onboarding and standardization
Migrating legacy .NET applications to modern architectural patterns

Not Ideal For

Teams building simple CRUD applications without complex domain logic or event-driven needs
Projects with aggressive deadlines that require rapid prototyping over architectural rigor
Environments with strict policies against third-party libraries like NetDevPack
Applications where database performance is critical and Event Sourcing adds unnecessary overhead

Pros & Cons

Pros

Clean Architecture Implementation

Provides full separation of concerns with SOLID principles and Clean Code, offering a clear blueprint for scalable .NET applications as detailed in the architecture section.

Modern Tooling Choices

Uses ASP.NET 9.0 and Entity Framework Core 9.0, replacing heavy dependencies like AutoMapper and MediatR with lightweight custom mapping and NetDevPack.SimpleMediator for a leaner codebase.

Comprehensive Learning Resource

Serves as a detailed reference for DDD, CQRS, and Event Sourcing, with practical examples and built-in architecture tests using NetArchTest.Rules to enforce design rules.

Easy Setup and Integration

Includes SQLite support with automatic EF Core migrations and JWT authentication setup in WebAPI, reducing initial configuration time and enabling quick starts.

Cons

Architectural Overkill

Implements multiple complex patterns like Event Sourcing and CQRS, which may be unnecessary for simpler applications, leading to increased development overhead and potential over-engineering, as cautioned in the disclaimer.

Dependency Lock-in Risks

Heavily relies on NetDevPack libraries for core functionality; if these dependencies become unsupported or incompatible with future .NET versions, it could require significant refactoring.

Steep Learning Curve

Assumes prior knowledge of DDD and CQRS concepts, making it challenging for developers new to these patterns to grasp the dense codebase without additional learning resources.
