import React from "react";
import Script from "react-load-script";
import Demo from "./Demo";

class App extends React.Component {
	state = { scriptLoaded: false };

	handleScriptError() {
		console.log("Error while loading script");
	}

	handleScriptLoad() {
		console.log("Script loaded successfully");
		this.setState({ scriptLoaded: true });
	}

	render() {
		return (
			<div>
				<Script
					url="/assets/js/your-script.js"
					onError={this.handleScriptError.bind(this)}
					onLoad={this.handleScriptLoad.bind(this)}
				/>
				<Demo ready={this.state.scriptLoaded} />
			</div>
		);
	}
}

export default App;
