What Hanami brings is an intentional and well-reasoned architecture that supports building maintainable applications. It has taste.
That statement means nothing. You could say the exact same thing about Rails and have an equally defensible position. What about its architecture makes it better?
I'm happy someone's challenging the Rails almost-monoculture in the Ruby ecosystem, but Hanami doesn't seem to bring much to the table. Is there anything in this release that Rails hasn't had for years?
I have loosely followed Hanami for years but never used it or heard of it used in a large codebase. I still don't quite understand what it does all that differently from Rails? There are plenty of comments that are along the lines of > "Hanami brings is an intentional and well-reasoned architecture that supports building maintainable applications.

We re-did our homepage recently, and we should make these things clearer. They're legitimate concerns and questions. We agree you don't have to write bad code in Rails, and we don't pretend that we can prevent bad code in Hanami. Instead we give application builders the tools to architect their applications in the way they desire. Really what we're doing is building an *option* for building Ruby apps that may speak better to some people. If you're completely happy with Rails then there's no reason to change. Still, you may learn something that'll help you build Rails apps by seeing how we do things. Additionally, it's completely modular: you can pull parts of Hanami into a Rails app. The most popular one people pull into Rails apps is dry-validation [1]
Some concrete differences:
- We have small, simple API's. Rails core classes have hundreds of methods for convenience, not to mention dozens of core extensions (a.k.a. monkey patches) to base Ruby classes. We prefer small, narrowly focused classes over large ones with many responsibilities.
- We have a dependency injection framework dry-system [2] included by default. This lets you write `include Deps["repos.article_repo"] to get an automatically instantiated (and now memoized!) `Repos::ArticleRepo.new` within your class. This makes dependencies trivial to stub out, and it also declares your dependencies in a single place, instead of littering constants throughout your code.
- We have sub-applications called Slices. Similar to Rails Engines but well... good, since they're a first-class concept that we encourage. Importantly, they're independently deployable. You can export and import components across slices, too. We can't tell you how to slice up your application, but we give you the tools to decide for yourself.
It'd be nice to see some benchmarks to compare the before vs after on the perf gains in the Faster by default heading. Love the work though; having beautifully crafted options like Hanami around is a joy.
Hanami is quite nice. I haven’t had the opportunity to use it in anger but I have had a crush on it for a while now. I really do hope ROM-rb, the not-orm Hanami uses, gets some development love as a consequence of this more formal merger. It’s a rad tool with enough rough edges that I had to switch away from it when launching a product a few years ago.
I have been using Rails 8 for the past few months on a work project, but the Hanakai ecosystem looks really, really interesting.
My one question would be whether or not Hanakai supports Inertia or Svelte views - we've been moving away from ERB recently, which has made it much easier to write interactive code due to the ecosystem, and I'd rather not throw that DX away!
Big congrats on the release! I have been using Rails 8 for the past few months on a work project, but the Hanakai ecosystem looks really, really interesting.

Hanami doesn't have any specific Inertia or Svelte specific integrations, but our view layer (and assets layer) is very flexible so it's certainly possible. It's worth investigating. If you try it out, let us know what you learn on our forum https://discourse.hanakai.org/

A long time ago I had a "Component Based Rails Application (CBRA)" using engines as the domain boundary. It was unpleasant because it just moved pain points into unfamiliar places. The slices approach is very interesting.
Overall I like dry-rb.
If I find myself on a ruby project again I will investigate more thoroughly!
