Migrating from monolithic rails

This document discusses migrating a monolithic Rails application to a more modular architecture by extracting the API into a separate Grape micro-framework. It notes that while Rails is nice for many things like routing, models, and persistence, extracting the API can improve performance, scalability, and make it easier to add other services over time. It encourages taking small, incremental steps towards this evolution by first moving the API into Grape and then potentially extracting other components.
Migrating from monolithic rails
- 1. Migrating from Monolithic Rails by Danielius Visockas Twitter: @DVisockas v1
- 2. Let’s look at Rails
- 4. Desktop only Extractions of patterns History of Rails
- 5. Let’s fast forward 10 years
- 6. Why Rails is nice: ● Routing ● Models (!) ● Persistence (migrations, schema) ● Sessions, cookies management ● Mailers ● Other stuff (rake tasks, assets pipeline, etc)
- 8. Story actually starts here
- 9. We had 2 apps Main Rails app and Sinatra for the API
- 10. In the main app we used plain Rails views and jQuery for the magic
- 11. Frontend magic 548 view files 84 javascript files some files that would make sense
- 12. Late extraction costs more than early abstraction Especially in frontend
- 13. && Your friends
- 14. Next thing: build an API That’s where Ruby is the best tool
- 15. Ruby API building tools
- 17. An opinionated micro-framework for creating REST-like APIs in Ruby. http://intridea.github.io/grape ● Specifically for building API’s ● Minimal ● Fast (Grape: 2227 req/sec vs RailsAPI: 1111.42 req/sec) on 1.9.3
- 18. Other cool features of moving to Grape ● Support from the community ● You already have models ● Documentation ● Easy integration into Rails
- 19. From evolution to revolution ● Small steps ● Reduced server load ● Easier to add other (micro-)services ● Easier scaling ● You can concentrate on one side of the app
