Does the world need another state management library? Probably not, but if you've been interested in XState, you're going to want to check this one out.

XState Store is a simple & tiny state management library largely inspired by XState. If you just need a way to update data in a store and subscribe to changes in the store, XState Store is for you. It is:

• Extremely simple. Provide initial context and transition functions to the createStore(…) function, and you're good to go.
• Extremely small. Less than 1kb minified and gzipped.
• XState compatible. Shares actor APIs with XState, making integration/migration easy if (when) you need to handle more complexity.
• Extra type-safe. Written in TypeScript, it provides strong event and snapshot types, automatically inferred from your context and transitions.
• Event-based. Works just like XState; send events to trigger transitions.
• Immer ready. Easily add Immer for "mutable" context updates with createStoreWithProducer(producer, …).
