On Change

Overview

Use state:onChange(fn) to subscribe to changes. The returned connection has a Disconnect() method.

local State = Katalyst.State

local s = State(0)
local conn = s:onChange(function(newVal)
  print("new val", newVal)
end)

-- later
conn:Disconnect()

Notes

• Subscriptions are fired asynchronously (batched) via task.defer.
