In my public/index.html I need to load external .js file which will be used later during deployment.
Unfornately that file doesnt load when i npm start, nor when published in build. I dont get any error either. The file config.js is in public directory as well.
Added this to my index.html in tag:
<script type="text/javascript" scr="%PUBLIC_URL%/config.js"></script>
config.js looks like this:
alert(5);
var test=5;
I get no error in console, but it doesnt resolve at all. Nothing happens.
(i've tried playing with paths, googling around for hours but no luck. I guess there must be some security setting in react or something that prevents me from loading that script?)
ps: i am tring this which is not working for same reason for me: https://www.cotyhamilton.com/build-once-deploy-anywhere-for-react-applications/
It's not my longest answer. You need to fix the typo, the correct attribute is src not scr on your script tag. If you change it, it will work fine:
<script type="text/javascript" src="%PUBLIC_URL%/config.js"></script>

I just set up a very basic Spring Boot Web Application with Thymeleaf, but I can't access my external JS file from the corresponding HTML file of my template and can't figure out why.
My resource folder structure is as follows:
static/
index.html
css/
graph.css
js/
createGraph.js
templates/
visualizeGraph.html
Within my visualizeGraph.html I try to call the createGraph.js using following snippet within the <body> element:
<script th:src="#{/js/createGraph.js}" type="text/javascript" >
</script>
In the <head> element of visualizeGraph.html, I added my stylesheet using following snippet:
<link rel="stylesheet" type="text/css" media="all"
href="/css/graph.css" th:href="#{/css/graph.css}" />
My Spring Boot Web Container runs on Port :8082, so I access my webapplication from localhost:8082 and access the visualizeGraph template from localhost:8082/visualizeGraph
When I check the Developer Console (F12), it throws a 404 for the createGraph.js file, but not for the graph.css file -> it can find the css successfully.
I can even access the css through localhost:8082/css/graph.css but CAN'T access the js-file using localhost:8082/js/createGraph.js (throws a 404 - as expected)
I can't figure, what's the cause for this phenomenon as my application.properties also has no additional parameters for modifying the resource source folder etc.
Okay, this was VERY weird. I found the solution, but I am not sure, whether it's IntelliJ, which was responsible for this problem or something else.
What I did was to edit my <script> element in my HTML file to the following:
<script src="/js/createGraph.js" type="text/javascript" >
</script>
and my intention was solely to try out, whether it would change anything. Somehow, IntelliJ told me, that it was not able to find the path (neither the js folder, nor the createGraph.js file within it) so what it suggested was to create the folder and the file (so I did, using ALT+Enter). What I did afterwards is to just copy the content of my old createGraph.js to the new file and to delete the (very strangely the same named) old folder and file and voila, everything works as expected... Very weird.
You can call your JS files present in resources/static folder like below:
<script type="text/javascript" src="js/script.js"></script>
No need to give the forward slash before the js folder.
below I am attaching screenshot for my code:
Here, I was having images folder inside the static folder so we can directly call that folder.

I'm a beginner at web dev, I'm currently working on a project, but the javascript file insert.js won't load. The html document, upload.html is inside the public folder, and the javascript is inside the main folder.
I used the following path to link the javascript file,
<script src= "../insert.js"></script>
But it didn't seem to work, so I then tried moving upload.html to the main folder, which is HR and I used the following code,
<script src = "/insert.js"></script>
And this didn't work either, so I then tried moving insert.js to the public folder, and used the same path as I have mentioned above, but, then I couldn't export variables to app.js which is located in the main HR directory.
The image I have attached shows location of the files
I don't get what could possibly cause this, I think I should mention this as well, but I got an error while running my javascript file in node. So I inserted the following code in node_modules/whatwg-url/dist/encoding.js:
const {TextDecoder, TextEncoder} = require("util");
I don't know if this has anything to do with my issue, but I thought I would just mention it.
localhost can only access your public folder, so you have to move insert.js in the public folder and do:
<script src = "index.js"></script>
Also if you have node modules in that javascript file it wont run because it can't run the modules and you would have to use a bundler for that js file like webpack, rollup or snowpack.
For my project I need to install the "Loadingbar.js" lib to one of my pages (which you can find here: https://loading.io/progress/).
I did paste the CSS in my global "style.css" file.
So, first, I just tried to put the <script></script> in my index:
<script type="text/javascript" src="assets/js/loading-bar.js"></script>
It worked for few hours, and now it does not work anymore. So I tried everything: I tried to put the <script> everywhere on each line of my index.html or even in the html of my page, in the body, under the body, under the <app-root></app-root>... nothing worked.
Also, the Angular project is sometime trolling me: the js is loaded once very rarely. If I refresh the page without changing anything- it does not work anymore.
I tried to add "defer" to the <script></script>.
I tried to wait document ready, I tried the setTimeout, but it never worked.
I tried to add the path to the script in "angular.json", didn't work.
What can I do to make this work? How do I add JS lib to an angular project?
Thanks.
First thing you should know is that in angular applications it's better to use npm dependency of any library if possible. If this is not possible and you need to use external js files, you can follow these steps:
First, put your js inside the node_modules folder. eg: node_modules/test-lib/loading-bar.js
Inside your app.module.ts, you can put this line at top of the file:
import test-lib/loading-bar.js(without node_modules)
Loading.io links their library to their GitHub account.
They offer an Angular example here:
https://github.com/loadingio/angular-loading-bar
It looks like the best approach is to install the library via npm or yarn.
I want to add some external file in Vue project like:
<script src="vlan/src/assets/js/three.min.js"></script>
<script src="vlan/src/assets/js/stats.min.js"></script>
console error image
The http://localhost:8080/vlan/src/assets/js/stats.min.js always show 404 error, but it works without adding the port。Did anyone met this before? I just want to know how to add lib file from the html template,please do't talk about require or import things, thanks in advance.
I am testing my website code, and I have the following folders in my working directory:
css
js
img
html (contains index.html)
When I try to bring up my website locally (the "index.html" inside of the html folder), none of the css or js files were found (404 Error).
However, before I made an html folder everything was linked together fine, and my file setup looked like this:
css
js
img
index.html
Also, when I created an "html" folder and put "index.html" inside of it, I changed the html code so that it would refer to the other files appropriately (from what I've seen on various websites):
<link href="../css/my_styles.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="../js/touch_functionality.js"></script>
<img src="../img/display_photo.jpg" alt="Display Photo">
Additional Information:
I am using a local Apache server to access the "index.html" file, and I have set the DocumentRoot for the VirtualHost I made to the "/html" folder.
Additionally, I thought this may have been a permissions error, but I downloaded Cygwin and I used "chmod 711" on all of the folders in my working directory and I have used "chmod 644" on the "index.html" file inside of the html folder, but the files still wouldn't be found.
I've done my research on this for quite a few hours, but unfortunately I haven't come across a solution for this yet. Any help would be much appreciated, thank you.
Update
If I change the DocumentRoot to where all of my working space directory (instead of html) and place a .php file that simply contains the following line of code:
<?php require("html/index.html"); ?>
where my folders reside so my working directory looking like this:
-css
-js
-img
-html (contains index.html)
-index.php
Everything will work correctly. However, I would have to believe there is a way so that I don't have to do this "work-around" method. Any insight would be incredibly helpful, thanks again.
The reason being is that the web server only allows one to view files in the html directory or below.
Otherwise it will somebody to access any part of your file system.
Would you like that?
To fix this go back to the configuration that works,
