Seems interesting.
How to use it with typescript, is there an example?

Thanks for your interest!
Totally supported typescript. Most types are calculated automatically. Only several places where are you need to define it manually.

When you define a parameterized action. (play on codesandbox)

// you should pass user type manually for an argument of action
const userUpdate = signal<string>();

// store type will be received from the initial state type
const store = value({ user: "" });

// all arguments will be typed automatically
store.update.by(userUpdate, (state, user) => ({
  ...state,
  user
}))

// only a string type allowed for an argument of action
userUpdate("John");
Enter fullscreen mode Exit fullscreen mode

Or in the shortcut for the above example. (play on codesandbox)

// you should pass user type manually for the second argument
const userUpdate = store.updater((state, user: string) => ({
  ...state,
  user
}));
Enter fullscreen mode Exit fullscreen mode

Types are calculated automatically as more as it possible 👍
