I have a simple React App that I'm trying to load through using a CDN vs NPM.
My options.html file:
<!DOCTYPE html>
<html>
<head>
<title>My Test Extension Options</title>
<script src="https://fb...me/react-0.14.3.js"></script>
<script src="https://fb...me/react-dom-0.14.2.js"></script>
</head>
<body>
<div id="root"></div>
<script src="index.js" type="text/babel"></script>
</body>
</html>
index.js
import React, { Component } from 'react'
import ReactDOM from 'react-dom';
class App extends Component {
render() {
return (
<div>Hello world</div>
)
}
}
ReactDOM.render(<App />, document.getElementById('root'))
When I load up options.html in a browser, nothing is showing up when I expected to see Hello world. I checked the debugger and no errors are coming up.
What am I doing wrong?
I believe :
There is no need of type="text/babel"
<script src="index.js" type="text/babel"></script>
so it should be
<script src="index.js" ></script>

Very new to React + Django
The frontend/src/components/App.js:
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
class App extends Component {
render() {
return <h1>React App</h1>
}
}
ReactDOM.render(<App />, document.getElementById('app'));
The frontend/src/index.js:
import App from './components/App';
Then I have the frontend/templates/frontend/index.html

When I run the server and go to localhost:8000:
The <div id="app"></div> remains empty. No errors raised.
I am not sure what the issue might be. I double checked the file against the tutorial I am following.
Trying to render a hello world but nothing is displayed on the page. There are no messages displayed in the console. What am I missing here? Thank you.

Your issue is that it is ReactDOM not ReactDom
class App extends React.Component {
render() {
return <h1>Hello from our app</h1>
}
}
var mount = document.querySelector('#app');
ReactDOM.render(<App />, mount);

I am creating Spring boot application and i want my frontend to be with React. The problem comes from the fact that i cannot find a way to properly integrate the react component in my jsp page.
Here is the declaration of the component:
ReactDOM.render(<App />, document.getElementById('root'));
I want to point out that my jsp page is inside WEB-INF directory and i can successfully redirect to it via a controller, but my import of the component does not work and does not throw an error!
I tried to import it by the element id:
<%# page contentType="text/html;charset=UTF-8" language="java" %>

Am i doing something wrong or missed some configuration?
Thanks in advance for your help!
After importing the React and ReactDOM scripts, import another script where you have written your component App. Assuming it is in App.js,
<script src="App.js"></script>
Now you need to render the component in the div with id="root". I will use babel to compile but you can do without it too. So after the import write:
<script type="text/babel">
ReactDOM.render(<App />, document.getElementById('root'));
</script>
Conclusion: Basically you need to import 4 files in this order: React, ReactDOM, Babel and your component.js files. Then you need to render the component in the div for it to work.
<script src="https://unpkg.com/react#16/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/babel-standalone#6.15.0/babel.min.js"></script>
<script src="App.js"></script>
<script type="text/babel">
ReactDOM.render(<App />, document.getElementById('root'));
</script>
I am trying to get a react JS app to render in IE 11 but it is not rendering. I believe I have tried all of the suggestions from https://github.com/facebook/react/issues/8379. This example renders fine in other browsers for me.
Here is my html file
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.3/JSXTransformer.js"> </script>
<script src="/static/js/test.jsx" type="text/jsx"></script>
</head>
<body>
<div id="root"></div>
<script type="text/jsx">
ReactDOM.render( < Test / > ,
document.getElementById('root')
);
</script>
</body>
</html>
and here is /static/js/test.jsx
class Test extends React.Component {
render() {
return ( < h1 > This is a test < /h1>);
}
One way to get it to work in IE11 is to import Babel to transpile ES6 to ES5 so it will work in IE11. Note that script type should be "text/babel" for both the inline script and the script import. Alternatively, you can transpile the javascript in the Babel repl and replace your code. Here's the html file
<!DOCTYPE html>
<html>
<head>
<title>First React App</title>

<div id="root"></div>

<script

></script>
<script src="./Test.js" type="text/babel"></script>
<script type="text/babel">
"use strict";
ReactDOM.render(<Test />, document.getElementById("root"));
</script>
</body>
</html>
here's Test.js
"use strict";
class Test extends React.Component {
render() {
return <h1>Hello World</h1>;
}
}
I am trying to use some pre-builtin react component from a library called ant design. Also, I would like to call the react and the component library through a cdnjs(don't wish to use webpack or else). How could I accomplish it? My approaches are like below and it's not working for me.

<script src="https://cdnjs.cloudflare.com/ajax/libs/antd/3.1.6/antd.min.js"></script>
</head>
<body>
<div id="root"></div>
<script type="text/babel">
import Button from 'antd/lib/button';
class Greeting extends React.Component {
render() {
return (<p><Button type="primary">Primary</Button></p>);
}
}
ReactDOM.render(
<Greeting />,
document.getElementById('root')
)
</script>
</body>
</html>
You don't need to import, because when you use prebuilt version, it's already injected into a global variable call 'antd' (just like React)
I also updated a little bit your scripts because for React you need . the umd version and antd needs the with locale version.
However, using prebuilt version is strongly NOT RECOMMENDED be careful.
