This project is a boilerplate for a backend application built with the Hono framework, utilizing Vertical Slice Architecture (VSA) and Clean Architecture. This combination is chosen because it provides a more manageable structure, is feature-centric, and simplifies development and maintenance. It is also a great starting point for applications that need to scale into multiple features or evolve into a microservices architecture.
By applying Vertical Slice Architecture (VSA) along with Clean Architecture, the project allows for easier management of features. The architecture splits the application into isolated slices, where each slice handles a specific feature, from the API to the persistence layer. This makes it easier to develop, test, and maintain each feature independently.
The feature-centric approach ensures that each feature is self-contained, promoting cleaner code and better organization. This isolation of features also makes it easy to scale and distribute parts of the application into separate microservices if needed, allowing for a more modular, maintainable, and scalable system.
This project boilerplate comes in three different types:
When I wanted to create a boilerplate for SvelteKit, I came across the Tofustack repository by @Rykuno, which is unique because it is combined with Hono. From there, I was able to understand the VSA structure implemented in Hono.
