I'm new to Reactjs and I'm trying to make a small localhost web application which accesses the webcam. I found a working example here. I have tried to implement it in Reactjs ES5 and SocketIO as shown below,
app.js
socket.on('sessionstarted', function (data) {
ReactDOM.render( <div><Webcam /></div>, document.getElementById('root'));
reactCookie.save('sid', data.id);
});
home.ejs

This implementation doesn't seem to work. I would really appreciate some help.

I can't seem to set this jquery datetimepicker. I believe I am following the instructions correctly. However, only the input box displays. After inspecting I saw these errors in the log
This the plugin I am trying to use.

previous code
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Home</title>
<link rel="stylesheet" type="text/css" href="/jquery.datetimepicker.min.css"/>

<body>
<input id="datetimepicker" type="text" >
</body>
<script src="/jquery.js"></script>
<script src="/build/jquery.datetimepicker.full.min.js"></script>

So I found the original files hereenter link description here
and then changed my code to the following

but now I have a new error. Any ideas on what I am missing?
Mind the order and dependencies of your scripts and use eventlisteners:
To make it simple:
Load CSS first (DateTimePicker), load JS second (jQuery, Datetimepicker), initialize an eventlistener using $().ready().
<!doctype html>
<html lang="en">

The code above will fix all your issues about where to put scripts and what to load (you where both loading the extended and minified version of the library)
See the following snippet:
jQuery('#datetimepicker').datetimepicker();
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jquery-datetimepicker/2.3.7/jquery.datetimepicker.min.css" />
<input id="datetimepicker" type="text">

Tell me please, how to connect external files with JSX to Html page

I upgraded from Angular 7.2 to Angular 8 and now all the Angular scripts are inserted at the very start of the HTML (before !DOCTYPE).
Is this a bug? Does anyone know what might be causing it?

My original HTML is pretty standard. The only oddities are an ng-app-settings.js script that loads some JSON for app config and the use of the TypeKit service for fonts. Neither of these caused a problem for Angular 7.

Thanks for any help
Try adding body tags to your HTML.
<!DOCTYPE html>
<html>
<head>
<base href="/" />
<title>My App</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link rel="icon" type="image/x-icon" href="favicon.ico?v=2" />
<script src="./ng-app-settings.js"></script>
</head>
<body>
<app>Loading...</app>
<script type="text/javascript" src="//use.typekit.net/abcdefg.js"></script>
<script type="text/javascript">try { Typekit.load(); } catch (e) { }</script>
</body>

I have two html files, the index.html and the game.html, i have the same links and scripts in the game's head.
i have try to put my code on the but thats not working.
I have search some hours but i can solve the problem.
Thanks for your help !
You should include only one version of jquery. Also you don't need both cordova.js and phonegap.js, choose one script.
Your code may look much more cleaner:
<!doctype html>
<html lang="fr">
<head>
<meta charset="utf-8">
<title>My app</title>
<meta name="viewport"
content="width=device-width, initial-scale=1.0, maximum-scale=1, minimum-scale=1, user-scalable=yes">
<link rel="stylesheet" href="Mobile_style.css">
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/smoothness/jquery-ui.css">
<link href='https://fonts.googleapis.com/css?family=Quicksand:700' rel='stylesheet' type='text/css'>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<script type="text/javascript" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
alert("Device is ready");
}
</script>
</head>
<body>
MY HTML
</body>
</html>
I've gone through the other solutions to this question and none seem to work. I still think there is a problem with the scripts. Here is my :
<head>
<meta charset="UTF-8">
<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1, minimal-ui" />
<!-- JQuery -->
<script src="js/jquery-1.11.3.js"></script>
<!-- BS -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />
<!-- Fancybox -->
<script type="text/javascript" src="fancybox/jquery.easing-1.3.pack.js"></script>

<link rel="stylesheet" type="text/css" href="fancybox/jquery.fancybox-1.3.4.css">
<!-- Custom CSS -->
<link rel="stylesheet" href="style.css">
<script>
$(document).ready(function() {
if(location.hash) {
$(location.hash).click();
}
$(".iframe").fancybox();
});
</script>
</head>
And body:
<a class="iframe" href="https://player.vimeo.com/video/151002965">
<img src="https://vimeo.com/151002965">
</a>
it have some type mistake
<script type="text/javascript" src-"fancybox/jquery.fancybox-1.3.4.pack.js"></script>
please correct it as,
<script type="text/javascript" src="fancybox/jquery.fancybox-1.3.4.pack.js"></script>
try once again it may help you
