HAL API libraries for Ruby
Evaluation of various HAL clients to build and consume HAL JSON APIs for Plannel. Evaluation purely by reading code and README. No Proof of Concept or experience with any of the libs.
The evaluation was done with a clear goal in mind: build the HTTP+HAL+JSON adapter on an existing business-domain that (hexagonal architecture). Preferably using Sinatra, since this HTTP adapter does not interact with databases or other plumbing etc: only with Models (Root Aggregates) and Commands. Clean, and easy to understand architecture is an important criteria. As are some other criteria: this is very opinionated and might not match what you are looking for, at all: it may very well be that something listed as "con" is a "pro" for you.
Tests for the API need a HAL client, the implementation needs a server. Client and server need not be the same library.
