JavaScript unexpected token '<' while working with ejx - node.js

I am just trying to link my javascript (resides in public folder) to my ejs but it keeps showing the same message 'unexpected token <'. The script is just empty. I'm not sure what is wrong. Here is the code

Vue code doesn't show up with Webpack Bundle Tracker

I run both the vue and the django.
I have installed webpack_loader and have it in installed apps.
I have the WEBPACK_LOADER in settings.py
WEBPACK_LOADER = {
'DEFAULT': {
'BUNDLE_DIR_NAME': 'dist/',
'STATS_FILE': os.path.join(BASE_DIR, 'frontend', 'webpack-stats.json'),
}
}
frontend is the name when creating vue.
Here is some more details KeyError at / 'assets' and ModuleNotFoundError: No module named 'webpack_loader'

When I use (django-webpack-loader 1.0.0), I get KeyError at /
When I use (django_webpack-loader 0.7.0), I get no errors, but the vue code doesn't show up (But I see it at localhost:8080).
Just started to work Today, I didn't do anything, and it started to work. I tried 2 times to make a new project with the same code, downloaded all the stuff again.
Didn't work. But then my vue code suddenly stopped working. I turned the server on and off. And then I saw that my vue code had been updated.
I then went to localhost:8000 to see if it worked, and it did.
I believe that God fixed it. Not sure what else it would be.
EDIT: 8 July 2022
I happened to get the error: TypeError: expected string or bytes-like object.
It was point to {% render_bundle 'chunk-vendors' %}
The problem was that I had upgraded the django-webpack-loader to the latest version, the error went away when I use this version django-webpack-loader==0.6.0.
I tried django-webpack-loader==0.7.0 and it works as well.
The version of webpack-bundle-tracker I'm using is 0.4.3

Angular production build with index.jsp instead of index.html

I want want to create an index.jsp file instead of index.html while doing production build. This weird requirement is for capturing the header part which we will getting from other Oracle Authentication Manager so I want load my appliation from index.jsp. My index.jsp should look something like this
<%# page language="java" import="java.util.*" session="true" %>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">

Any suggestion to do this.
I suppose you only want the index.jsp when doing the production build. The development process should still use index.html
In that case you should
Create a index.jsp file in the same directory as your index.html file (so you have both).
Update your angular.json file's production configuration by adding an index property to your production configuration like this:
That will make sure that it uses index.jsp when you build with --prod, but still uses index.html for development.

.net core 2 angular 5 prerender failed

I'm getting the following error:
NodeInvocationException: Prerendering failed because of error: ReferenceError: window is not defined
I have followed the following documentation from microsoft themselves:
https://learn.microsoft.com/nl-nl/aspnet/core/client-side/spa/angular?view=aspnetcore-2.0&tabs=visual-studio
So the prerendering gets triggered but it fails because on the server side window does not exist ofcourse.
Now i have seen fixes for the older angular template from Visual Studio which came with Angular 4. The one from the documentation has Angular 5 and is build up a little different. So I have found fixes but they do not work because I do not have an index.cshtml. In the new template you get a normal index.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Test/title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<script src="https://use.fontawesome.com/93acba991a.js"></script>
</head>
<body>
<app-root>Loading...</app-root>
</body>
</html>
The solution for the first project was :
replace the "asp-prerender-module" with "asp-ng2-prerender-module"
As you can see i do not have a asp-prerender-module in there, and changing it to "asp-ng2-prerender-module" does not work for me. I'm using the #agm/core package which gives me this error, but i heard multiple packages suffer from this problem. I hope anyone has a fix for this issue.

Use custom jquery.js with Bootfaces

I use Bootfaces version 1.1.3 and I try to provide a custom version of jquery as described here:
CSS files, JS files and CDNs
These are my first lines of my template:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:b="http://bootsfaces.net/ui" xmlns:p="http://primefaces.org/ui">
<h:head>
<title>Internet Domains</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta charset="utf-8" />
<h:outputScript name="/reg/js/jquery-1.11.1.min.js" position="first" />
And this is what was finally generated:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head><link type="text/css" rel="stylesheet" href="/reg/resources/theme.css?ln=primefaces-aristo" /><link rel="stylesheet" type="text/css" href="/reg/resources/css/other/core.css?ln=bsf" /><link rel="stylesheet" type="text/css" href="/reg/resources/css/bsf.css?ln=bsf" /><!--[if lt IE 9]><script src="/reg/resources/js/html5shiv.js?ln=bsf"></script><script src="/reg/resources/js/respond.js?ln=bsf"></script><![endif]--><script type="text/javascript" src="/reg/resources/jq/jquery.js?ln=bsf"></script><script type="text/javascript" src="/reg/resources/jsf.js?ln=javax.faces&stage=Development"></script><script type="text/javascript" src="/reg/resources/js/alert.js?ln=bsf"></script><script type="text/javascript" src="/reg/resources/js/bsf.js?ln=bsf"></script><script type="text/javascript">if(window.PrimeFaces){PrimeFaces.settings.projectStage='Development';}</script><meta name="viewport" content="width=device-width, initial-scale=1"/>
<title>Internet Domains</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta charset="utf-8" />
<script type="text/javascript" src="/reg/js/jquery-1.11.1.min.js"></script>
I expected that the <script type="text/javascript" src="/reg/resources/jq/jquery.js?ln=bsf"></script> will be replaced by <script type="text/javascript" src="/reg/js/jquery-1.11.1.min.js"></script>. This is how I understood the documentation. But it does not happen. I can avoid including the query.js?ln=bsf useing the web.xml parameter net.bootsfaces.get_jquery_from_cdn. But I need to load jquery before Bootfaces load alert.js and bsf.js. Can anyone help me to get this working?
The algorithm recognizing the custom jquery library only checks if the filename begins with "jquery". In your case, BootsFaces 1.1.3 is confused by the folder name. I've corrected this after seeing your bug report, but the bugfix will only be available in BootsFaces 1.2.0, which today (Dec 17, 2017) hasn't been released yet (but should be released soon).
So either you try the developer preview BootsFaces 1.2.0-SNAPSHOT or you can move the jquery.js file to the root folder. Alternatively, you can add the attribute lib to specify the subfolder of the jquery.js file. Note that the latter option also means you have to put the file into the ressources folder.

Express Server not Serving Static Files from Index.html

This question has been asked multiple times I know, but I have searched and tried everything, and it still doesn't work. I'm new to Node. My file directory is set up like this:
io
-node_modules/
-app/
--css
--js
-index.html
-server.js
Server.js:
var express = require('express');
var app = express();
//app.use(express.static(__dirname+'/app/css'));
app.use('/css', express.static(__dirname+'/app/css'));
var server=require('http').createServer(app);
var io=require('socket.io').listen(server);
users=[];
connections=[];
//set up server
server.listen(process.env.PORT || 3001);
console.log('Server running...');
//create a route
app.get('/',function(req,res){
res.sendFile(__dirname+'/app/index.html');
});
Index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<!-- Always force latest IE rendering engine (even in intranet) & Chrome Frame
Remove this if you use the .htaccess -->
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

So what I need to know is why index.html doesn't seem to able to reference my css files. I've tried multiple possible combinations in app.use() and it just doesn't want to work, even though at times I can get to the file directly from the browser.
in the server:
app.use(express.static(__dirname+'/app/css'));
in the client:
<link href="/main.css" rel="stylesheet">
<link href="/bootstrap.css" rel="stylesheet">
I think you're using the app.use wrong
Try it like this :
app.use('css', express.static(__dirname+'/app/css'));
this routes calls to css/... to the static dir named.
