Clean Rails Example

A dockerized example of using clean architecture in rails. This is a simple Blog API for now, which supports a simple posts API.

Quick Tour

• /lib/blog_app - application-level code
• /lib/blog_app/use_cases - application use cases, (aka interactors)
• /lib/blog_app/entities - domain entities
• /lib/blog_app/repos - abstract repository definitions (adapters for data access)
• /app, /config, /db - rails-specific code
• /app/repos - rails-specific implementations of the repo definitions
• /app/serializers - presentation-specific logic for converting domain entities to json

Setup

run docker-compose up app to launch the app on localhost:3000

Testing

run docker-compose run --rm app rspec to run the test suite

Using the app

To create a new post, run e.g.

$ curl http://localhost:3000/posts -X POST -H 'Content-Type: application/json' \
  --data '{"author":"Connie Contentwriter","title":"Creating Posts","body":"Post posts by POSTing to /posts"}'
