I found many projects that required a server. My question how do I start Visual Studio Code like any other jQuery/React/Angular library? How do I start it from the browser without using a server?
I know that I will need to provide the files using a script.
I don't need the extension marketplace, terminal and similar. I only need the files tab on the left, the search tab, and the editor itself. The editor is Monaco, I found out. But I didn't find something that also contains the files panel and the tabs switcher (The list of opened files).
There are projects like code-server, but it requires a server. It also should be executed by our clients, so I don't want resources or security risks on the server.
So how do I compile and embed Visual Studio Code into a Web page to be served by a static HTML server?
Could somebody advise me on which project type should I use to develop client side of web-based app (HTML + JavaScript) for Visual Studio 2013?
I tried to create New, Web Site, ASP.NET Empty Web site, then manually added all .js files to the project, but this is not exactly what I need, because I am working on a client-side code only, and the Web server is not IIS.
Of course, when a script error occurs, I can select “Debug using selected debugger”, manually choose my project and jump into debugging. However, this is only a half-solution.
First, I cannot start debugger with F5 – it launches web page connected to local IIS instead.
Second, I have duplicate source trees in solution explorer- the debugger does not match my source files with files loaded with web pages.
I have also tried New, Other project types, Visual Studio solution, Add existing Web site, and played with Start Options, but without much success too. It launches page in IE, but with script debugging disabled (???), and it does not start the debugger anyway.
Is there an appropriate project type to write and debug JavaScript for IE?
PS: When installing VS, I selected C++ development, as my primary settings, which might hide some useful Web development features. And I would prefer not to change this.
UPDATE: Problem #1 (starting with F5) was solved by setting IE as default Web browser (I have used Firefox). After specifying “Specific page” in Start options F5 starts the page under debugger.
Is it possible to debug scripts under IE, leaving my favorite browser as default? If I specify “Start External program” and set “iexplore.exe” with page url, it launches the page but does not allow me to debug it.
you have a bunch of questions in here, but let me try answer them.
To develop client-side of web-based app, Create an ASP.NET Empty Web site and manually add HTML + JavaScript
If the Web Server is not IIS, then you can change, right-click on your project in VS-2013, and in properties,check Web properties.
To Debug your HTML and JavaScript in IE, then follow this:
you have to enable Script debugging in IE as follow:
let, if you have a function named FirstFunction() in your HTML page then
<script type="script/javascript">
function FirstFunction()
{
debugger;
alert("Debugging now");
}
</script>
I am trying to test some JavaScript on my local computer using the Chrome browser but Chrome will not load local resources. Is there an easy work around for this?
If you are trying to just test the functionality of your JavaScript file: create a blank HTML file, add a link to your JS file as you would normally load a JS file from HTML, and open the HTML file in Chrome. Go to the JavaScript console. You'll be able to interact with the functionality of your JS code as usual. You wouldn't need to set up a server for this. If still not clear, here's an example:
<html>
<head>
<script type = "text/javascript" src = "path/to/your/jsfile"></script>
</head>
</html>
You can use a light weight webserver to serve the file.
For example,
1. install Node
2. install the "http-server" (or similar) package
3. Run the http-server package ( "http-server -c-1") from the folder where the script file is located
4. Load the script from chrome console (run the following script on chrome console
var ele = document.createElement("script");
var scriptPath = "http://localhost:8080/{scriptfilename}.js" //verify the script path
ele.setAttribute("src",scriptPath);
document.head.appendChild(ele)
The script is now loaded the browser. You can test it from console.
To load local resources in Chrome when just using your local computer and not using a webserver you need to add the --allow-file-access-from-files flag.
You can have a shortcut to Chrome that allows files access and one that does not.
Create a shortcut for Chrome on the desktop, right click on shortcut, select properties. In the dialog box that opens find the target for the short cut and add the parameter after chrome.exe leaving a space
e.g. C:\PATH TO\chrome.exe --allow-file-access-from-files
This shortcut will allow access to files without affecting any other shortcut to Chrome you have.
When you open Chrome with this shortcut it should allow local resources to be loaded using HTML5 and the filesystem API.
For security reasons, modern browsers won't load resource from locally running HTML files (files using file:// protocol in the address bar).
The easiest way to get a modern browser to load and run JavaScript files in local HTML files is to run a local web server.
If you don't want to go through the trouble of setting up a Node or Apache web server just to test your JavaScript, then I'd suggest you install Visual Studio Code and the Live Server extension.
Visual Studio Code
Visual Studio code is a source code editor for pretty much any programming language under the sun. It has built-in support for JavaScript, HTML, CSS, TypeScript, and almost any kind of language used for Web development.
Install Visual Studio Code
You can get the Visual Studio Code editor for your platform from https://code.visualstudio.com/. It supports Windows, Linux, and Mac. I think it also works on your Surface Pro if that's your thing.
Add the Live Code Extension
After installing VS Code, you can add the Live Code code extension using the Extension panel (Ctrl+Shift+X in Windows) in Visual Studio Code.
Live Server Extension
After adding the extension, you should see a "Go Live" button in the bottom-right corner of the Visual Studio Code IDE (as shown in the above screenshot).
Open in Code
Open the root folder where your HTML and JavaScript files exist in Visual Studio Code and click the "Go Live" button. Optionally, you can right-click the HTML file in the Explorer (Ctrl+Shift+E) and select Open with Live Server from the pop-up menu that appears.
Open with Live Server
This should create a locally running web server and open the file or folder in your web browser. If your file paths are correct, your JavaScript files should also load and run correctly.
Troubleshooting
If for some reason, the page doesn't load in your favorite browser, check that the address and port number are correct. If the Live Server is running, it should display the port number in the bottom-right corner of the Visual Studio IDE. Make sure the address in your browser says http://127.0.0.1:<PORT>/index.html where <PORT> has the same number as shown in the status bar in Visual Studio Code.
Use Chrome browser and with the Web Server for Chrome extension, set a default folder and put your linked html/js files in there, browse to 127.0.0.1:8887 (0r whatever the port is set at) in Chrome and open the developers panel & console. You can then interact with your html/js scripts in the console.
The easiest workaround I have found is to use Firefox. Not only does it work with no extra steps (drag and drop - no muss no fuss), but blackboxing works better than Chrome.
You can do it by a feature of chrome's DevTools: Snippets
Create a new snippets
Copy and paste the file you would like to execute.
Hit CtrlEnter to run the snippet
Windows 8.1 add:
--allow-file-access-from-files
to the end of the target text box after the quotes.
EX: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files
Works like a charm
Running a simple local HTTP server
To test such examples, one needs a local webserver. One of the easiest ways to do this is offered by Python's SimpleHTTPServer (or http.server, depending on the version of Python installed.)
# 1. Install Python 3 & use:
python3 -m http.server
# On windows, instead of "python3" try "python" or "py -3"
# If you installed python version 2 then use:
python -m SimpleHTTPServer
# 2. To serve a specific folder use the --directory flag:
python3 -m http.server --directory /Users/junaid/WebstormProjects
# Note: I use MacOs & I have given the absolute path to my projects folder & I was able to serve my desired folder.
Here's what I did by creating 2 files in the /sandbox directory:
First file: sandbox.js
Second file: index.html
const name = 'Karl'
console.log('This is the name: ' + name)
<html>
<head>
<script type = "text/javascript" src = "file:///Users/karl/Downloads/sandbox/sandbox.js"></script>
</head>
</html>
You can then use Chrome or any browser to inspect and debug/console your code!
setup
You will want to serve the file from a web server. Everything else will be quirky workarounds that might differ greatly from the final result. On the web, files are being served via web servers. You'll want to mimic that locally.
Since you're apparently (at least part-time) being a web developer, do yourself a massive favour and install node, if you haven't already. It comes bundled with the npx binary, which we'll use. Make sure you have a recent LTS version. Bonus points for using n, which will make it easy to stay up to date with your versions, and even switch them as you need.
steps to take
Inside the folder where your file is located: npx http-server -c-1
You can now access the file at http://127.0.0.1:8000/filename
Last thing to do is make the browser load the file. Magesh's answer works well for that, but I would recommend putting that snippet into a "custom js" extension. This one has served me well so far.
With everything in place, simply reload the page to get an updated version
of your local file.
Note: this question comes top on google when you search for "chrome read local css without server". So...
If you really want to serve a local webpage and load its CSS and JS, and you really do not have or don't want to use a http server, then don't load the scripts nor styles; inline them.
Instead of something like this:
<link rel="stylesheet" href="somefile.css">
Define the style like:
<style>/*Here goes all the CSS file content*/</style>
And the same with the JavaScript files. The HTML file will be larger, but it will work.
Basically you just have to copy the file contents and paste it inline.
You really should use a server, but if you are forced to, you can use this method.
If you still need to do this, I ran across the same problem.
Somehow, EDGE renders all the scripts even if they are not via HTTP, HTTPS etc...
Open the html/js file directly from the filesystem with Edge, and it will work.
for my use case, i need to startup a local server, create working an interactive html page, and open it for the user to be able to interact with it. the problem was how to set the local server's web root to my temp working folder where i create these dynamic files. this was a quick and dirty solution.
In the below code, LOCAL_WEB_DIRECTORY is essentially the root. and i then create/copy the files i want to open in the brower to that directory + /templates
import webbrowser
from http.server import ThreadingHTTPServer, SimpleHTTPRequestHandler
httpd = ThreadingHTTPServer(('', 8001), lambda *_: SimpleHTTPRequestHandler(*_, directory=config.LOCAL_WEB_DIR))
server_thread = threading.Thread(target=httpd.serve_forever, daemon=True)
server_thread.start()
webbrowser.open('http://localhost:8001//templates/' + work_html)
while True: sleep(1)
Not sure why #user3133050 is voted down, that's all you need to do...
Here's the structure you need, based on your script tag's src, assuming you are trying to load moment.js into index.html:
/js/moment.js
/some-other-directory/index.html
The ../ looks "up" at the "some-other-directory" folder level, finds the js folder next to it, and loads the moment.js inside.
It sounds like your index.html is at root level, or nested even deeper.
If you're still struggling, create a test.js file in the same location as index.html, and add a <script src="test.js"></script> and see if that loads. If that fails, check your syntax. Tested in Chrome 46.
The easiest way I found was to copy your file contents into you browser console and hit enter. The disadvantage of this approach is that you can only debug with console.log statements.
Look at where your html file is, the path you provided is relative not absolute. Are you sure it's placed correctly. According to the path you gave in the example above: "src="../js/moment.js" " the JS file is one level higher in hierarchy.
So it should be placed as following:
Parent folder
sub-folder
html file
js (this is a folder)
moment.js
The double dots means the parent folder from current directory, in your case, the current directory is the location of html file.
But to make your life easier using a server will safe you troubles of doing this manually since the server directory is same all time so it's much easier.
I've been working through the javascript remote debug tutorials for WebStorm / IntelliJ(numbers.js)
I've managed to get remote debugging working successfully, however there is one thing that is making life difficult.
When I'm debugging numbers.js in WebStorm(I've also tested in IntelliJ and have same result) there is a little lock icon which I guess implies that the file is read only. At the moment, it is slow and painful to go full cycle on the development / deploy process of:
code modification on local file
upload
debug on locked remote fuile
switch tabs in WebStorm to local file
code modification on local file
What I want to do at least is debug on local file, so that I can make changes while debugging and then quickly upload and repeat.
# the tutorial
http://wiki.jetbrains.net/intellij/Remote_JavaScript_debugging_with_WebStorm_and_PHPStorm
the numbers.js file does not have the locked symbol in the tab like I am seeing in my locally running WebStorm.
Anyone else have this problem? Anyone advise how they got WebStorm working so they can make changes to the local file while stepping through and debugging?
Thanks
Most likely you open the file from the Scripts tab in the Debugger panel and place breakpoints there. You should place breakpoints in the original file instead.
Deployment can be automatic (on Save) or you can use In Place configuration when your server root is configured to the project folder.
Another important thing is the local file to remote URL mapping in the Debug configuration. Note that in the wiki tutorial Remote URL is set to the full URL including the http:// and server name.
With In Place deployment or with Automatic Upload and correct mappings you can debug your scripts with zero turnaround time. Make a change, switch to a browser, Refresh (file is saved automatically as Settings | General | Save files on frame deactivation is enabled by default).
If it doesn't work this way for your project, please contact JetBrains support and send a sample project to reproduce this problem, also describe your server and deployment settings.
is there anyway to stop popping up the warning message in IE when trying to execute javascript?
I want some solution which does not need modifying the settings in the IE manually by the user.
Thanks,
If the message is only appearing for you when you run the scripts locally and not for your visitors when you upload your scripts to the server, I'd suggest one of three things:
Have a test server that you can use to run the things you are developing. This will avoid issues that might come up when you are running scripts locally. Apache or IIS should allow you to do this, although you will have to research how to get the server you choose to use working like your production environment (example: PHP).
If you want to continue to test your scripts locally, you can give your pages the Mark of the Web (<!-- saved from url=(0014)about:internet -->). This will force the page to run in the Internet Security Zone and avoid the message you see when you open an HTML file containing script locally.
If there is some reason you can't give the pages the MOTW, you can configure Internet Explorer to allow scripts to execute locally (note this is a bit dangerous since local files containing script can do something malicious). Go to Tools > Internet Options > Advanced tab > scroll to the Security section and check Allow active content to run in files on My Computer
This only occurs when you open local files. And no; there's no way to avoid this.
Or so I thought.. Untill Grant Wagner came by and gave his two cents :)
