Smart elevators

Smart elevators

Design and implement an elevator control system.

Work process:

• Initial thought process\plans brainstorm.md
• Factual time spent: ~12 hours, due to
  • scala.js weird quirks I was not aware of (workbench stop updating js properly for no reason etc) investigate!
  • initially thought of doing Diode's event-based model (and started working on implementation) but that looked like an over-engineering given small time constrains (immutable model with event handling is tricky)

Techs that was used

• Plain step-based control system implementation
• Monocle lib to zoom into model properties
• Scala.Js UI for demo purposes

See demo gh-page

See Smart elevators demo here https://aafa.github.io/smart-elevators/index.html

Run locally

• sbt test to run tests covering basic scenarios
• sbt ~fastOptJS to iterate over Scala.js UI

Further plans

• Address minor todos\concerns mentioned through the code
• Step-based approach is very simple and straightforward however I'd like to see event-driven design for better interaction handling and more smooth UI flow (listen to events and update only parts that was changed etc.)
