Dynamically set the file path for static files in the index.html file in a React app via a JSON file

I'm trying to dynamically set the file paths to the static files (js & css) in the index.html file of my create-react-app such that they can point to different sub-directories depending on what I set in a settings.json file.
Example:
If I set the base_url in my settings.json file like this:
{
"BASE_PATH_URL": "/subdirec1"
}
I expect the file path in my index.html file to be like this:
<script src="/subdirec1/static/vendors/js/core/jquery-3.2.1.min.js" type="text/javascript"></script>
I'd be grateful if anyone could help me out here. Thanks!

If you're using webpack, you can use webpack variables that you can set within the webpack config object, which themselves come from a .json/.js file.
This is the example you can use if you're using webpack!
WARNING: Don't use the command below before reading up on it, because it will make a big mess of files you might not understand yet!
Since you're using create-react-app, I think it uses webpack under the hood but you need to npm run eject it to have more complete access to its configuration!

I can't use Javascript in Dreamweaver

My Javascript wont activate on dreamweaver. I attached it and everything but when i try to call it with script tags it does not appear on my live preview. i have it attached by this code
<script src="file:///C:/Users/Matthew/Desktop/Untitled-2.js" type="text/script"></script>
If someone could please help that would be awesome! :D

Live mode runs Your code in some virtual webserver and it cannot get local js file. Since browser may block resource from sharing (CORS). Think about putting js file to relative to html file and defining relative url to js file. Create js folder near to html file and put js file there and in Your html file define src="js/Untitled-2.js" – num8er 12 mins ago

In my opinion, it is best practice to keep all files relative to the project. This means setting up a project folder and keeping files organised in sub-folders.
Consider this project structure:
Project folder
CSS folder
style.css
Javascript folder
script.js
Images folder
image.jpg
index.html
The sub-folders are directly children of the project folder, and inside each folder is the corresponding files.
The html file is also a direct child of the project folder (it's not in any other folder).
This means all the related files are relative to the html file.
So in your html file, you can link up these files easier.
<link href="CSS/style.css" rel="stylesheet">
<script src="Javascript/script.js" type="text/javascript"></script>
<img src="Images/image.jpg">
As you can see all the files are linked without a full path, this is called relative linking. Absolute linking is the opposite in which you specify the full path, such like you are doing at the moment:
<script src="file:///C:/Users/Matthew/Desktop/Untitled-2.js" type="text/script"></script>
This is good in certain places, however you should always try to aim for relative linking. If you follow this, you shouldn't have any more problems.

How to run a custom html file with budo (or browserify)?

Budo does great job to browserify and run with livereload. But it is using index.html by default. That makes it less convenient with several html files. Is it possible to run it against a custom html file?
It mentions to accept all browserify options but I couldn't find the relevant one.

You can use the dir flag to point to a custom path where you house a different index.html file:
eg: budo index.js --dir myCustomBudoDir
this will serve your index.html out of your myCustomBudoDir directory

If your launch dir has an index.html, budo will use that. I've got a super simple project here.

Currently, Budo has the name index.html baked in, so using separate directories is the way to go, see the dir option in the doc

How to Use or Import jQuery custom builder in a Notepad, Sublime etc...

I just want to ask how to use the jquery custom builder since i separate the folder of jquery custom builder to the Login Folder. Here is the folder path for the jquery custom builder
And here is for the Login Folder
I have tried this kind of syntax for getting the Directory of the js file and to other files to but it doesn't seems to work.
<script src = "‪../htdocs/WebSite/jslib/jquery-ui-1.11.4.custom/jquery-ui.js"></script>
i hope you can help me with this since i'm just starting jquery i also read the guide for using jquery i follow the instruction but it's still the same.
Thanks

Where is the html file that imports jquery script tag? It seems like just path problem. Usually, URI paths are based on app server root. There are so many ways managing URI, but XAMPP might let file resource paths show up same as URI paths.
When app server root is located on c:/foo/bar/:
c:/foo/bar/lib/jquery.js -> http://localhost:xxxx/lib/jquery.js
c:/foo/bar/index.html -> http://localhost:xxxx/index.html
So in index.html, import resource as this way.
<script src="‪lib/jquery.js"></script>

Insert QML code in Jade

I'm writting a simple video streaming app with Node.js and I'm using the WebChimera plugin. With chimera, the player config is written in QML and I must include it in my .jade page and of course, there's many errors when jade compiles.
Is there a way to include QML in jade?

In your Jade try including an iframe(src='/qmlfiles/my.qml') and create a subfolder called qmlfiles in your /public folder. And then put your qml content in that my.qml file. Express will then see that since qmlfiles is in /public it won't try to interpret it. This is based upon the assumption that .qml has some mime association to it that a browser would understand.
If not, then my.qml might instead just be my.html and it could include QML content. Again, locating it under /public would mean that Express doesn't use the rendering of Jade in order to try to deal with it.
