Please I am trying to run react app using external CDN, and having issues on the html file saying:
Uncaught ReferenceError: require is not defined index.html:3 This is the html code:
<!DOCTYPE html>
<html>
<head>
<meta charset='UTF-8'>
<link rel="stylesheet" href="styles/style.css">
<script src='https://unpkg.com/react@16.3.1/umd/react.production.min.js'></script>
<script src='https://unpkg.com/react-dom@16.3.1/umd/react-dom.production.min.js'></script>
<script src='https://unpkg.com/react-router-dom@5.0.0/umd/react-router-dom.min.js'></script>
<script src='https://unpkg.com/babel-standalone@6.26.0/babel.js'></script>
</head>
<body>
<div id='root'></div>
<script type='text/babel'>
import Todo from 'component/Todo.js';
const App = () =>(
<div>
<h1>My Todos</h1>
<Todo />
</div>
)
ReactDOM.render(<App />, document.querySelector('#root'));
</script>
</body>
</html>
And this the JavaScript code
function Todo (){
return (<div className="card">
<h2>TITLE</h2>
<div className="actions">
<button className="btn">Delete</button>
</div>
</div>);
}
export default Todo;
you can import external scripts from another server like this :
componentDidMount() {
const script = document.createElement("script");
script.src = "/static/libs/your_script.js";
script.async = true;
script.onload = () => this.scriptLoaded();
document.body.appendChild(script);
}
Then to make sure your file is loaded :
scriptLoaded() {
// your stuff to do!
}
Another way is using react Helmet:
first install it using :
npm install --save react-helmet
then use it like this
<Helmet>
<script src="www.test.ts" />
</Helmet>
note that in this way your script will load in the <head>
