import { VirtualDOM, createElement, Component } from "dcbl";

interface ClickerState {
  clicks: number;
}

// extending basic component class
class Clicker extends Component<any, ClickerState> {
  // initialazing state in constructor
  constructor() {
    super({});
    this.state = { clicks: 0 };
  }
  // rendering the button element and provide props to it
  render() {
    return <button onclick={this.addOne}>{String(this.state.clicks)}</button>;
  }
  // method which is provided to button element as event listener
  addOne = () => {
    this.setState({ clicks: this.state.clicks + 1 });
  }
  // changing title of document after the component updated
  componentDidUpdate() {
    document.title = `clicks: ${this.state.clicks}`;
  }
}

// creating new virtual dom
const vd = new VirtualDOM();
// generating DOM tree from virtual dom
vd.createTreeFromRoot(
  <Clicker />,
  document.querySelector("body") as HTMLBodyElement
);
