A super simple redux connect() implementation

connect.js

import store from 'store/store';

const connect = (mapStateToProps) => (Component) => {
  class Connect extends React.Component {
    constructor() {
      super();
      this.state = {};
    }

    componentDidMount() {
      this.unsubscribe = store.subscribe(this.update.bind(this));
    }

    componentWillUnmount() {
      if (this.unsubscribe) this.unsubscribe();
    }

    update() {
      this.setState(mapStateToProps(store.getState()));
    }

    render() {
      return (
        <Component { ...this.state } />
      )
    }
  }

  return Connect;
};


export default connect(mapStateToProps)(Component);
