I recently tried PhpStorm and it's great especially with the completion.
When I Ctrl + Space (mac) I get suggestions that actually exist, like when I'm in a JS file and my project has jQuery I get Element Suggestions when typing $("#.
But in VS Code it feels like all suggestions come from AI and aren't even based on what is present in my project.
EDIT: Because I have difficulties describing what I mean I uploaded this video to help you understand my problem
Is there any way to get similar behavior in VS Code?
Yes, there is a way to improve IDE suggestions, and that is by installing extensions for the particular programming language that you use.
So, based on the tags you added for your question, for PHP, you can install "PHP Intelephense", for jQuery you can install "jQuery Code Snippets" and for HTML install "HTML CSS Support".
You can very easily install all 3 extensions by clicking on the "Extensions" option on the left hand side of the IDE (little cubes).
I am trying to find the way to debug javascript code inside the php file. I have a lot of javascript code embedded inside the php file.
I can debug php code using netbeans with the help of XDebug. I can also debug javascript separately inside html or js file with browser like chrome or firefox.
What I want is to debug javascript code inside the php file if it is possible. I am sure a lot of people will be using javascript embedded with php file. I don't like it personally, but I have to work it on. I know I can write the code separately in js file and then can debug with browsers, but it's lot of code, take time for the separation.
Can anybody here suggest me a way if it's possible what I am asking.
Debug Javascript in netbeans 7.4 inside PHP project
https://netbeans.org/kb/docs/php/debugging.html

https://blog.jetbrains.com/phpstorm/2014/06/debugging-php-and-javascript-code-at-the-same-time/
IMHO, without even looking it up, i don't think that it is (nor should) be feasible.
Here's why:
Your PHP gets processed on the server side, that's when XDebug kicks in and enables you to breakpoint all your PHP code. Then the server output gets to the client, that's when the actual JS is processed inline in the parsed HTML. Which means you would have to intercept the HTML in some way, parse it, detect eventual inlined JS scripts... and set your breakpoint(s) at that time (yes on each run), then output to client, which parses the HTML yet again to render it and process eventual breakpoints. It would be a tedious process and even more tedious to get to work i guess and that is why nobody even tried making an extension for that.
To my knowledge, inlined JS is also a lot harder to debug and i never saw an actual setup that would allow breakpointing embedded tags in a static HTML document directly from the IDE, which would've been somewhat a little easier to achieve than breakpointing JS in PHP...
Your best shot i guess would be to externalise your JS in separate files and only hard code <script src="path/to/your/app.js"></script> in your PHP templates, which indeed would be much more comfortable to work with on the long run anyways.
Then you would be able to breakpoint all the stuff in app.js, plus have an actual front-end architecture, syntax-highlighting, impress your boss, make your life a lot easier, the world a better place, etc.

Edit: seems like setting JS breakpoints in static HTML tags is feasible in Visual Code for example -> https://github.com/Microsoft/vscode-chrome-debug/issues/122
I don't know if I am late, but, I came across the following website and was able to setup the debugger for Javascript and PHP which supports to debug embedded JavaScript in PHP scripts.
source: https://abcmemo.com/2017/04/20/debug-php-and-javascript-in-visual-studio-code/
The website uses PHP.exe as a web service.
It is also possible to use IIS, Apache or others.
Requirements:
IDE: Visual studio code
Extension: PHP debug
Extension: Debugger for (Chrome, Firefox or Edge)
Xdebug set in php.ini
Extension in browser (optional): PHP xdebug if you want to debug on trigger.
You need to have two debuggers running at the same time one for PHP and one for JavaScrpit.
PHP sample
JavaScript sample
I worked with a lot of wordpress templates where I had to deal with some js inside my php files. Assuming that you can run your code on a server, you can easily debug your output in dev tools in chrome (if using chrome). Chrome also allows for setting of breakpoints so you can go line by line, and since your browser ultimately runs the js, you can monitor your code behavior without dealing with the php. That was my main way of dealing with this issue.
I also recommend separating as much js as possible into separate files in your assets folder. Depending on your project, you rarely have to inline your code, In my opinion it's messy to include a lot of JS right in your php, unless you use onclick="" or onchange="" attributes (which can also be handled with event listeners.
Aside from that, console.log() the crap out of everything.
I helped my self with the following steps if it could help any body else
Note:- If your rendered code is inline specific to java-script then it would hard to debug like this.
Run the required page of your application using browser like chrome, edge etc
Open the inspection page by pressing f12 or (Ctrl+Shift+I), Or you can right click on the page see the option for the inspection and click on it.
Goto sources and double click on the source file(this will be probably your php file).
If code not loaded then reload the page by pressing f5 or Ctrl+R, you will see your java-script code there embedded with the html after rendering, then you can put the break point wherever you want and debug through the browser tools(you can see some buttons there to guide you about debugging like step-over,step-into etc).
You will also see errors there regarding java-script,
Browserify great and all, and makes it really sweet (even compared to require.js), but the idea of bundling everything into one minified file although sounds great for final version of the app, feels like something I would like to avoid during development. Wouldn't it make difficult to debug stuff?
Is it possible to use browserify and still keep all javascript files and make it more transparent for the browser during development? And when you ready to ship it run browserify bundler and minify everything into one file?
Or maybe there's better approach - like keeping all scripts listed in a partial that gets included to the main page for development or something like that?
Upd: I just found that there's an option:
--debug -d Enable source maps that allow you to debug your files separately.
Is that helpful? I guess it is. But I suppose it still makes it difficult if want to use coffeescript source maps
Indeed you shouldn't use minified/concatenated Javascript in development. Luckly there are a myriad of ways of solving this particular issue, I recommend taking a look into an automated build process like Grunt.
I am editing a JavaScript file in MyEclipse.
When I try to change some content, I currently have to restart Tomcat.
If I don't, the change will not take effect.
By the way, I am using Chrome.
Is there a good way to make my changes take effect immediately without restarting Tomcat?
Thank you!
You can simply copy your JavaScript file into the deployment directory when you're done editing it.
The deployment directory is where Tomcat places your files when it builds and deploys.
I don't know exactly where it is for Tomcat, but it should be pretty easy to determine.
I typically use a little shell script to make this more convenient.
I have a web project I'm working on and it is using LESS to combine all the files into one CSS for me. However I obviously don't want the client side javascript to have to run in production as that is going to slow things down.
Is there a way with the client-side less.js that it can export the .less files you give it to a single CSS file, which I could then call in my live environment?
You have a couple of options for this that I know of:
Use the LESS command line tool
If you're on a Mac, use LESS.app
Running a watch command isn't that big of a deal, it becomes second nature quite quickly :)
Since you want a non-command line option, I'd recommend LESS.app if you're running OS X. If not, try Simpless (cross-platform) or Crunch (Adobe Air-based).
PS. They're all free!
