🤔 What is it?

A small but opinionated Vertical Slice Architecture solution template for .NET 8

Learn

🎉 Getting Started

To install the template from NuGet.org run the following command:

dotnet new install Hona.VerticalSliceArchitecture.Template

Then create a new solution:

mkdir Sprout
cd Sprout

dotnet new hona-vsa

Finally, to update the template to the latest version run:

dotnet new update

📚 Faster Development

To speed up development there is a dotnet new template to create a full Vertical Slice.

dotnet new hona-vsa-slice -f Student

-f or --feature where the feature name is the singular name of the feature.

Of course, there are always exceptions where appending an 's' is not enough. For example, Person becomes People and Child becomes Children.

For this, use the optional parameter:

dotnet new hona-vsa-slice -f Person -fp People

optional: -fp or --feature-plural where the feature name is the plural name of the feature.

This creates everything you need to get started with a new feature.

• Full CRUD endpoints
• CQRS
  • missing EventHandlers/ folder as this is more uncommon
  • provides Events/ as a folder to demonstrate how to trigger side effects
• Basic REPR pattern (i.e., Request, an Endpoint, and a Response)
• Adds a new Entity
• Basic DDD pattern - the 'Complete' method on the entity shows adding Domain events and using Result objects instead of exceptions for validation
• Adds a DbSet to the DbContext
• Adds EF Core Entity Type Configuration
• Adds a Repository

While there is a small amount of code to remove, it is better to push you towards the pit of success, than allow inconsistency.
