XState Ninja von Richard Laffers

XState Ninja is a devtool panel for tracking state machines implemented with the XState library. It provides a better developer experience than the widely used Redux devtools extension for monitoring state machines. XState Ninja is more ergonomic and removes common pain points experienced with Redux devtools:

👉 more than one machine can be tracked at once in multiple swim lanes
👉 the machine state is clearly visible (including parallel states)
👉 no events are missed regardless of when the devtool was opened
👉 side effects (invoked services and actions) are clearly visible
👉 all invoked or spawned actors are monitored, including invoked/spawned callbacks and promises
👉 dead actors are clearly marked (💀) so there is no confusion if multiple machines of the same ID are started
