jQuery v3.5.1 standard build works, the slim build does not, what are the missing dependencies for Draggable to work with the jQuery slim build?
Reproduction code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<!-- Work -->
<!-- <script src="https://code.jquery.com/jquery-3.5.1.js"></script> -->
<!-- Does not work -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<span id="draggable">Drag me around</span>
<script>
$('#draggable').draggable()
</script>
</body>
</html>
Error in console:
I've tried the following imports to include potential dependencies, but didn't succeed:
import $ from 'jquery/dist/jquery.slim.js'
import 'jquery/src/manipulation/_evalUrl.js'
import 'jquery/src/deprecated/ajax-event-alias.js'
import 'jquery/src/effects.js'
import 'jquery/src/effects/Tween.js'
import 'jquery/src/effects/animatedSelector.js'
import 'jquery-ui/ui/widgets/draggable.js'
And surprisingly, the minified jQuery didn't work either:
import $ from 'jquery/dist/jquery.min.js'
import 'jquery-ui/ui/widgets/draggable.js'
Only the normal build worked:
import $ from 'jquery/dist/jquery.js'
import 'jquery-ui/ui/widgets/draggable.js'

I follow this video to open an HTML file and JS file in VSC. but I can't render the js file on the web.The hi I am tom hi is not appear on the web.
index.html

</html>
index.js
function App(){
return(
<div> hi I am tom hi </div>
);
}
ReactDom.render(<App/>,document.getElementById("app"))
Update the last line in index.js to:
ReactDOM.render(<App/>,document.getElementById("app"))
and it'll work.
Explanation:
What was wrong in your index.js?
Ans: ReactDOM is an object which is imported from react library to handle the rendering the component. In your code you were accessing ReactDom, note the caps are different, you were referring to ReactDom instead of ReactDOM.
Remember that JavaScript is a case-sensitive language.
This is my html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="root"></div>
<script src="index.js"></script>
</body>
</html>
```
Javascript
import React from "react"
import ReactDOM from "react-dom"
ReactDOM.render(
<h1>Hello, world!</h1>,
document.getElementById('root')
);
The problem is that there are no problems and nothing shows up on the output as wrong. I made sure to save my code and rebooted VS code a bunch of times. I installed all the libraries and was following a tutorial. Then for some reason it isn't working.
After npm init and installation of react, react-dom, bootstrap and react-bootstrap packages, I can't import any component from react-bootstrap library, as import Button from 'react-bootstrap/Button'; produce TypeError: Error resolving module specifier: react-bootstrap/Button.
I get rid of that error by changing the path to import Button from './node_modules/react-bootstrap/Button' - it's correct path, but when I try to render anything it doesn't change the div in target .php file, there's not any error in the console, so I lost. I use Babel babel-cli#6 babel-preset-react-app#3 preprocessor for JSX translation.
Here is preprocessed index.js:
import Button from 'react-bootstrap/Button'
class ProfilePage extends React.Component {
render() {
return (
<div>
<p>blah blah blah blah blah</p>
</div>
);
}
}
ReactDOM.render(<ProfilePage/>, document.getElementById('app'))
and index.php:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

/>
<script>var Alert = ReactBootstrap.Alert;</script>
<script type="module" src="./index.js"></script> <!-- processed index.js -->
</body >
Output is: inner html.
Without react-bootstrap import it works perfectly, bootstrap also, but of course I'm not able to use react-bootstrap components. What am I missing?
I think your import syntax is just off. Instead of
import Button from 'react-bootstrap/Button'
Try
import { Button } from 'react-bootstrap’
Or
import { Button } from 'react-bootstrap/Button'
if the above doesn’t work.
Almost done learning React on Codecademy, so I wanted to start coding something in it on my PC. I have put the directory onto my XAMPP server, but the React app still won't render.
class LandingPage extends React.Component {
render() {
return (
<h2>Hello</h2>
);
}
}
ReactDOM.render(<LandingPage />, document.getElementById('app'));

I don't think any browser by default understands JSX. You need to set up the chain to compile your source to pure JS.
If you only want to play around I recommend using the Create React App.
See: https://reactjs.org/docs/installation.html#creating-a-new-application
I followed facebook's tutorial to learn react. I used npm create-react-app to create a react app. Html files are in a folder called public . JS and CSS files are in a folder called src.
This is my index.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>React App</title>
</head>
<body>
Link
<div id="root"></div>
</body>
</html>
This is my index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render(
<App name="Sumanth Jois"/>,
document.getElementById('root')
);
index.html works fine . <App/> is being rendered on to the screen.I have another file which login.html.
This is login.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>React App</title>
</head>
<body>
<div id="app"></div>
</body>
</html>
This is my login.js :
import React from 'react';
import ReactDOM from 'react-dom';
ReactDOM.render(
<App name="Sumanth Jois"/>,
document.getElementById('app')
);
But this time login.html is display nothing it's empty. Can somebody please tell me where I am going wrong? I am stuck with this for hours now.
