Typestate Guard
Playground What is Typestate? Typestate programming is a pattern for enforcing run-time order of operations at compile-time. In State Machine term, this make it impossible for sending an event that doesn't transition to any state when specific state is active. Most of the time…

Initialising a state machine in a specific state in xState and React
I have a form and I want to load it up in the state it was last used in. I can store the last used state in a database. I'm using @xstate/react, is there a way to pass in a state to useMachine(stateMachine); for it to initialise in ? Has anyone found a way to do this?

How to model a bouncing ball? (or: patterns for simulating physics)
I'm trying to create a game using statecharts, but I'm not sure if I'm on the right track regarding modeling the animation/physics. Let's say I want to model a bouncing ball: then natually its state can be either "in_air" or "bouncing"(when it touches the floor). In my design,…

Extracting Keys from a Machine reliably (with TS tools)
I'm trying to separate the machine from a React component that sends events that will be handled by it. I.e. a machine with OPEN, CLOSE events is not used in the component that gets a send function and sends those OPEN, CLOSE events (unlike useMachine from @xstate/react that…
