.Net Can't Load Javascript - javascript

I added some js files which were exported from Adobe Muse to my wwwroot/js folder. However, when I check the console, it doesn't look like these folders can be found.
I am calling the scripts using:
<script src="~/js/require.js?crc=4157109226" type="text/javascript" async data-main="~/js/museconfig.js?crc=4153641093" onload="if (requirejs) requirejs.onError = function(requireType, requireModule) { if (requireType && requireType.toString && requireType.toString().indexOf && 0 <= requireType.toString().indexOf('#scripterror')) window.Muse.assets.check(); }" onerror="window.Muse.assets.check();"></script>
The errors I'm getting are below:
And finally I have my folders set up as follows

data-main attribute is read by requirejs and not by Razor engine. That is why requirejs being a JavaScript library will not be able to resolve ~ in the path. Use Url.Content for that, like below.
data-main="#Url.Content("~/js/museconfig.js")"

How to make source maps available with requireJS in Tapestry 5

My goal is to use Bootstrap5 Tooltips with my Tapestry 5.8.1 web application. I try to use requireJS for my JavaScript code as much as possible. So I use the Bootstrap5 JS files in their separated form. That means, I don't use the bundle file but single files like this:
src/main/resources
- META-INF
- modules
- bootstrap5
- alert.js
- alert.js.map
- base-component.js
- base-component.js.map
- ...
- tooltip.js
- tooltip.js.map
In my own JS I activate the tooltips by defining this module:
define(["bootstrap5/tooltip"], function(Tooltip) {
var setuptooltips = function() {
var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new Tooltip(tooltipTriggerEl)
})
};
return {
"setuptooltips" : setuptooltips
};
})
and then calling require(...).setuptooltips().
That all works. But.
For each *.js file in my modules/bootstrap5 directory I now get a warning on the JavaScript console about the missing source map files:
Source-Map-Fehler: Error: request failed with status 404
Ressourcen-Adresse: http://localhost:8080/webapp/modules.gz/bootstrap5/tooltip.js
Source-Map-Adresse: tooltip.js.map
And I don't know how to resolve this. Tapestry stores all the modules that are actually used in this modules.gz path. I have to knowledge of the inner workings of this. In the debugger I can browser this path and only the files that have been loaded via require() calls are listed their. Obviously, the source map files are missing. Is there a way to either resolve the issue or at least remove the warnings without the need to edit all the Bootstrap5 JS files? Since it is those JS files that refer to the source map files.
Thanks!

How to use different syntax for same file extension on Sublime Text? (JS/JSX)

With Sublime Text, is it possible to use different syntax for a same file extension depending on the currently opened project ?
Example :
Project A : file.js contains classic Javascript
Project B : file.js contains JSX
How can I obtain JavaScript syntax for project A and Babel syntax for Project B?
Just for background (which you likely already know), Sublime Text applies a syntax via the extension of the file, and overriding that requires you to use View > Syntax > Open all with current extension as... from the menu. This creates a syntax specific override which appears in a specific file name and is thus not directly overrideable on a per project basis.
That said, it is possible to swap the syntax on your own (e.g. via the command palette) which opens the possibility of a plugin being able to do this for you. There may be an existing plugin that does this in PackageControl, but for reference purposes, here is an example based on something I'm using for a similar purpose.
The following assumes that you're using the Babel plugin to get your syntax highlighting, since you mention Babel. This would need to be modified if this is not the package you're using. This could also be modified to similarly do a swap for a different type of file if desired.
To use this, select Tools > Developer > New Plugin from the menu and replace the entire contents of the sample file with the code below, and then save it as a python file in the directory that Sublime suggests (which should be in Packages\User). I named mine js_syntax_swap.py, but the name doesn't matter as long as the extension is .py:
import sublime, sublime_plugin
# Standard Sublime JavaScript syntax file is:
# 'Packages/JavaScript/JavaScript.sublime-syntax'
#
# The Babel package syntax is:
# 'Packages/Babel/JavaScript (Babel).sublime-syntax'
class JavaScriptSyntaxSwap (sublime_plugin.EventListener):
def modify_syntax (self, view):
if view.window () == None:
return
swapSyntax = view.settings ().get ('using_babel_js', False)
curSyntax = view.settings ().get ('syntax')
variables = view.window ().extract_variables ()
extension = variables['file_extension']
if swapSyntax is True and extension == 'js' and "Babel" not in curSyntax:
view.set_syntax_file ('Packages/Babel/JavaScript (Babel).sublime-syntax')
def on_load (self, view):
self.modify_syntax (view)
def on_post_save (self, view):
self.modify_syntax (view)
With this in place, if you choose Project > Edit Project from the menu, you can include a using_babel_js setting to enable the plugin for JavaScript files in that project. An example might be:
{
"folders":
[
{
"path": "."
}
],
"settings":
{
"using_babel_js": true
}
}
What this is doing is checking every time you load or save a file to see if it should swap the syntax from the default to the Babel JSX syntax, which it does only for files with the extension .js that are not already using Babel as the syntax.

Requirejs, basic information

I'm learning Requirejs and I started with two simple .html pages: index.html and second.html.
On the index.html I worte:
<script data-main="assets/js/app.min" src="js/vendor/require.js"></script>
The app.min.js file look like this:
requirejs.config({
baseUrl: 'js/vendor',
paths: {
app: '../app',
jquery: 'jquery-1.10.1.min'
}
});
requirejs(["app/main"]);
My app/main.js file has just a jQuery alert:
define(['jquery'], function($) {
$(function() {
alert('Hello World');
});
});
It works fine!
Now I'm worried just about one thing... What about if I need to load the app/main globally for all my pages and then another file like app/second that run only on second.html page?
Probably I'm missing something about Requirejs... I don't thinks that I need to load everything on the app.min.js file like did for the app/main.
I understand that I can define modules on separate js files but then how can I manage different files for different pages without loading everything in just one file? Probably I'm wrong, I hope you can open the light in my brain for that.
Thanks
I understand that a page might need its own code in addition to what is in app.min. You could do something like this:
<script data-main="assets/js/app.min" src="js/vendor/require.js"></script>
<script>
// You can call the config function as many times as you need to add new configuration.
requirejs.config({
// Presumably, baseUrl does not need to be changed.
// baseUrl: 'js/vendor',
paths: {
// additional paths you may need
}
});
// This loads the code proper to this page.
requirejs(["app/second"]);
</script>
If app/second depends on app/main make sure to have that dependency listed in app/second's define call.
Take a look at this example: https://github.com/requirejs/example-multipage. The example demonstrates how you can create page1.js and page2.js and in those files load the common stuff + page specific things. That's one of several ways to do it.
Another way to do which is what I often use is putting something like this in all your pages:
<script src="require.js"></script> <!-- just require -->
<script src="app.min.js"></script> <!-- your config and also loading the main module -->
and then on second.html, you would also add this
<script>require(["app/second"])</script>
You can use this setup for development, and for production you can replace the first 2 lines with just <script src="optimized-bundle.js"></script>. The optimized-bundle.js could include require.js + config + app/main + app/second. Or if you want to load app/second only on the second.html in production to make your main script smaller, you can have require.js + config + app/main in the primary bundle and optimize app/second into a separate bundle - the html would stay the same in both cases.
Hope this helps.

JS Lint for Visual Studio 2010 problems

I have a file with a JS object:
function Monitor() {
var self = this;
...
And I have a file that creates an instance of this and uses it.
self.monitor = new Monitor();
The files are included in a cshtml file in order:
<script type="text/javascript" src="#Url.Content("~/Scripts/Shared/Monitor.js")"> </script>
<script type="text/javascript" src="#Url.Content("~/Scripts/Views/NewMonitor_Index.js")"></script>
The problem is I get this error:
Warning 1 JS Hint: 'Monitor' is not defined.
How do I configure it so that it finds the monitor object?
I don't think if there is an automatic way. Although JSHint could detect other script tags, it is probably more difficult to get the actual path to the file.
Anyways, if I know that a certain symbol is definitely available in the context, I add a
/*global Monitor*/
at the beginning of the script.
If a symbol will be available in every script, I add it to my .jshintrc file in the directory, like
{
"predef": [
"Monitor"
]
}
But I don't know if/how this works on Windows.

Is it possible to stop requireJS from adding the .js file extension automatically?

I'm using requireJS to load scripts. It has this detail in the docs:
The path that is used for a module name should not include the .js
extension, since the path mapping could be for a directory.
In my app, I map all of my script files in a config path, because they're dynamically generated at runtime (my scripts start life as things like order.js but become things like order.min.b25a571965d02d9c54871b7636ca1c5e.js (this is a hash of the file contents, for cachebusting purposes).
In some cases, require will add a second .js extension to the end of these paths. Although I generate the dynamic paths on the server side and then populate the config path, I have to then write some extra javascript code to remove the .js extension from the problematic files.
Reading the requireJS docs, I really don't understand why you'd ever want the path mapping to be used for a directory. Does this mean it's possible to somehow load an entire directory's worth of files in one call? I don't get it.
Does anybody know if it's possible to just force require to stop adding .js to file paths so I don't have to hack around it?
thanks.
UPDATE: added some code samples as requested.
This is inside my HTML file (it's a Scala project so we can't write these variables directly into a .js file):
foo.js.modules = {
order : '#Static("javascripts/order.min.js")',
reqwest : 'http://5.foo.appspot.com/js/libs/reqwest',
bean : 'http://4.foo.appspot.com/js/libs/bean.min',
detect : 'order!http://4.foo.appspot.com/js/detect/detect.js',
images : 'order!http://4.foo.appspot.com/js/detect/images.js',
basicTemplate : '#Static("javascripts/libs/basicTemplate.min.js")',
trailExpander : '#Static("javascripts/libs/trailExpander.min.js")',
fetchDiscussion : '#Static("javascripts/libs/fetchDiscussion.min.js")'
mostPopular : '#Static("javascripts/libs/mostPopular.min.js")'
};
Then inside my main.js:
requirejs.config({
paths: foo.js.modules
});
require([foo.js.modules.detect, foo.js.modules.images, "bean"],
function(detect, images, bean) {
// do stuff
});
In the example above, I have to use the string "bean" (which refers to the require path) rather than my direct object (like the others use foo.js.modules.bar) otherwise I get the extra .js appended.
Hope this makes sense.
If you don't feel like adding a dependency on noext, you can also just append a dummy query string to the path to prevent the .js extension from being appended, as in:
require.config({
paths: {
'signalr-hubs': '/signalr/hubs?noext'
}
});
This is what the noext plugin does.
requirejs' noext plugin:
Load scripts without appending ".js" extension, useful for dynamic scripts...
Documentation
check the examples folder. All the info you probably need will be inside comments or on the example code itself.
Basic usage
Put the plugins inside the baseUrl folder (usually same folder as the main.js file) or create an alias to the plugin location:
require.config({
paths : {
//create alias to plugins (not needed if plugins are on the baseUrl)
async: 'lib/require/async',
font: 'lib/require/font',
goog: 'lib/require/goog',
image: 'lib/require/image',
json: 'lib/require/json',
noext: 'lib/require/noext',
mdown: 'lib/require/mdown',
propertyParser : 'lib/require/propertyParser',
markdownConverter : 'lib/Markdown.Converter'
}
});
//use plugins as if they were at baseUrl
define([
'image!awsum.jpg',
'json!data/foo.json',
'noext!js/bar.php',
'mdown!data/lorem_ipsum.md',
'async!http://maps.google.com/maps/api/js?sensor=false',
'goog!visualization,1,packages:[corechart,geochart]',
'goog!search,1',
'font!google,families:[Tangerine,Cantarell]'
], function(awsum, foo, bar, loremIpsum){
//all dependencies are loaded (including gmaps and other google apis)
}
);
I am using requirejs server side with node.js. The noext plugin does not work for me. I suspect this is because it tries to add ?noext to a url and we have filenames instead of urls serverside.
I need to name my files .njs or .model to separate them from static .js files. Hopefully the author will update requirejs to not force automatic .js file extension conventions on the users.
Meanwhile here is a quick patch to disable this behavior.
To apply this patch (against version 2.1.15 of node_modules/requirejs/bin/r.js) :
Save in a file called disableAutoExt.diff or whatever and open a terminal
cd path/to/node_modules/
patch -p1 < path/to/disableAutoExt.diff
add disableAutoExt: true, to your requirejs.config: requirejs.config({disableAutoExt: true,});
Now we can do require(["test/index.njs", ...] ... and get back to work.
Save this patch in disableAutoExt.diff :
--- mod/node_modules/requirejs/bin/r.js 2014-09-07 20:54:07.000000000 -0400
+++ node_modules/requirejs/bin/r.js 2014-12-11 09:33:21.000000000 -0500
## -1884,6 +1884,10 ##
//Delegates to req.load. Broken out as a separate function to
//allow overriding in the optimizer.
load: function (id, url) {
+ if (config.disableAutoExt && url.match(/\..*\.js$/)) {
+ url = url.replace(/\.js$/, '');
+ }
+
req.load(context, id, url);
},
The patch simply adds the following around line 1887 to node_modules/requirejs/bin/r.js:
if (config.disableAutoExt && url.match(/\..*\.js$/)) {
url = url.replace(/\.js$/, '');
}
UPDATE: Improved patch by moving url change deeper in the code so it no longer causes a hang after calling undef on a module. Needed undef because:
To disable caching of modules when developing with node.js add this to your main app file:
requirejs.onResourceLoad = function(context, map)
{
requirejs.undef(map.name);
};
