Hi @bradwoods , this feature was added here and is going to be released in version 3.4.

In V4 this will be:

myMachine.getStateNode('foo'); // retrieves myMachine.states.foo
myMachine.getStateNode('#someStateID'); // retrieves (nested?) state with id: someStateId

// alternatively:
myMachine.getStateNodeById('someStateId'); // same as above

myMachine.getStateNodeByPath('foo.bar.baz'); // retrieves nested state with path ['foo', 'bar', 'baz']
myMachine.getStateNodeByPath(['foo', 'bar', 'baz']); // same as above

This is to disambiguate a "State" and "StateNode", which are two different things.

This is now in master and the latest xstate@next.
