Back in October/2015 – Hanami was called Lotushttp://hanamirb.org/blog/2016/01/22/lotus-is-now-hanami.html

Starting up a Proof of Concept

The selection• Hanami Model• Repositories• Entities• Object Mapping• Sequel abstraction

• Hanami Validation• Input Filtering• Input Validation

The Requirement

• Asset Pipeline• ERB-like Views• Javascript helpers

We’re asked to keep Rails under the hood due frontend requirements

The Plan

https://github.com/hlegius/hanami-rails-as-frontend

Right after* PoC’s approval

All frontend-related stuff goes to

applications

Actually, it was 5-7 days after PoC’s approval =P

Rails autoloading Hell

http://urbanautomaton.com/blog/2013/08/27/rails-autoloading-hell/

After 7 months, Rails decided to demand attention

Good bye Rails; Hello Hanami (again)

Changes applied in Production env in 5 working days

Final considerations• Your team must be engaged and

accept the adoption• You can not do this alone! (read it

multiple times)

• PoC is a game changer• Practice; Practice; Practice*

• Hanami v0.7.3 is not ready for production, they say.
