import { wapper } from 'resa-class-model';

interface AppProps {
  count: number;
  appModel: AppModel;
}

class App extends React.Component<AppProps> {
  render() {
    return (
      <div className="App">
          <h1>{this.props.count}</h1>
          <button onClick={() => this.props.appModel.add(1)}>+</button>
          <button onClick={() => this.props.appModel.minus(1)}>-</button>
          <button
            onClick={
              () => this.props.appModel.addAsync(2)}
          >async
          </button>
          <button
            onClick={
              () => wapper(this.props.appModel.addAsync(2)).then(() => { alert('callback'); })}
          >promise
          </button>
      </div>
    );
  }
}

const mapStateToProps = (app, state) => ({
  count: app.appModel.state,
});

const NewApp = connect(mapStateToProps, ['appModel'], null)(App);

// AppModel.ts
import { Model, reducer, init, effect } from 'resa-class-model';
import { delay } from 'redux-saga';

@init({
    name: 'appModel',
    state: 0

    @effect()
    * addAsync(count: number) {
        yield delay(2000);
        this.add(count);
    }

    @reducer()
    add(count: number) {
        return this.state +  count;
    }

    @reducer()
    minus(count: number) {
        return this.state -  count;
    }
}

// index.ts
import createResa, { Provider } from 'resa';
