🍔 Sliders

Sliders are mini "app-folders" for grouping related code in your Rails application.

Like a slider is not really a burger 🍔 this is not really app folders 😉

Some times you have bundles of code in your app that is related to some specific feature. Extracting to a gem is not really an option as the feature is tightly integrated with the rest of the application. So how do you get a good structure of files in you application?

(Yes, I've been inspired by, or envious at, Hanami and their slices for structuring a Hanami application.)

With sliders you get a namespace folder that groups all you files.

Going from:

app/
├─ controllers/
│  └─ my_feature/
│     ├─ first_controller.rb
│     └─ second_controller.rb
├─ models/
│  └─ my_feature/
│     ├─ record_a.rb
│     └─ record_b.rb
├─ jobs/
│  └─ my_feature/
│     └─ run_in_background_job.rb
└─ interactors/
   └─ my_feature/
      └─ important_feature_task.rb

To:

app/
└─ sliders/
   └─ my_feature/
      ├─ controllers/
      │  ├─ first_controller.rb
      │  └─ second_controller.rb
      ├─ models/
      │  ├─ record_a.rb
      │  └─ record_b.rb
      ├─ jobs/
      │  └─ run_in_background_job.rb
      └─ interactors/
         └─ important_feature_task.rb

Future plan is to group all your sliders tests in a test/sliders/my_feature folder as well.

Add this line to your application's Gemfile:

gem "sliders"

And then execute:

$ bundle

Create your slider folder

$ rails g slider my_feature

This creates the app/sliders/ folder and a module and folder for your feature.

Now you can just use regular generators to create thing in MyFeature namespace and sliders will create the files in your slider folder.

The folder sliders is not used for namespace, just like the folders in your slider is not used. So a file in app/sliders/my_feature/models/admin.rb will be for the constant MyFeature::Admin.

Generators that will now create files in slider folder:

• controllers
• scaffold
• helpers
• mailers
• jobs
• active record model

Feel free to open PR with fixes for generators for that creates files outside of sliders folder.

Known generators that will not do what you expect:

• view
  • controller
  • mailer
  • scaffold
• action cable
• action mailbox
• tests
  • controller
  • model
  • scaffold
  • mailer
  • job
  • integration
  • helper
  • system?
• fixtures (part of model tests)
• components?

Other things we need to fix:

• loading fixtures from slider fixture foldeer
