rko - npm Package Versions

Commands will now use the id property from the command object as a fallback if the id argument is not provided to setState.

// `onStateDidChange` will be called with (state, "added_message")
addMessage(newMessage) {
  this.setState({
    before: { message: this.state.message },
    after: { message: newMessage }
  }, "added_message")
}

// `onStateDidChange` will be called with (state, "cleared_message")
clearMessage() {
  this.setState({
    id: "cleared_message",
    before: { message: this.state.message },
    after: { message: "" }
  })
}

// `onStateDidChange` will be called with (state, "flipped_message")
reverseMessage() {
  this.setState({
    id: "reversed_message",
    before: { message: this.state.message },
    after: { message: [...this.state.message].reverse().join("") }
  }, "flipped_message")
}

Changes stack from private to protected. This allows extending classes to make the stack public if they wish.

class Example extends StateManager {
  get history() {
    return this.stack
  }
}
