The question is, Eclipse IDE for JavaScript and Web Developers and Eclipse IDE for Java EE Developers, are both different IDEs, right? Assuming that, i can use the tools at Eclipse IDE for JavaScript and Web Developers like a eclipse java EE perspective? If not, what tools i can use to write javascript at Java EE IDE?
Thanks in Advance.
I really always hate to see folks being snippy in their answers, I apologize for the answers you got so far.
The core differences are:
Java:
The essential tools for any Java developer, including a Java IDE, a Git client, XML Editor, Mylyn, Maven and Gradle integration
Web/JavaScript:
The essential tools for any JavaScript developer, including JavaScript, TypeScript, HTML, CSS, XML, Yaml, Markdown... languages support; Kubernetes, Angular and React frameworks support; Node.js debugger; Git client; Mylyn task management; integrated terminal and remote filesystem explorer; Web and application server management.
At the end of the day its all about which packages come pre-installed. You can choose to start with one and then add the packages you want from the other. To see which specific pages are installed with either go here:
Java: https://www.eclipse.org/downloads/packages/release/2019-09/r/eclipse-ide-java-developers
Web/JavaScript: https://www.eclipse.org/downloads/packages/release/2019-09/r/eclipse-ide-web-and-javascript-developers-includes-incubating-components
As the Eclipse site clearly shows, the different versions contain different modules; in this case one has modules for JS and Web development, the other for Java EE development. Just download the version that has all the modules.
I use two different IDE's based on what I'm doing. My primary IDE is Visual Studio, whereby I use Chirpy to mash and minify my code. It works flawlessly and I love it. Problem is that when I'm not on my Windows box, I don't have access to it.
When not using Visual Studio, I'm usually writing Javascript apps in Webstorm on my Macbook Pro. Here in lies the problem. I haven't found a Webstorm plugin or any other app that I can configure to watch my scripts and mash/minify them.
How do you Mac users mash/minify your JS and CSS at design time with minimal effort?
For those who have now updated to WebStorm 6, this functionality is in-built. Simply go to File (or whatever the Mac equivalent is) -> Settings -> File Watchers and define a file watcher for the type of file you need to watch.
The relevant help documentation is here - http://www.jetbrains.com/webstorm/webhelp/using-file-watchers.html
You could use YUI Compressor without Command Line with these little Apps:
http://www.webmaster-source.com/minimus/ – free
http://www.matmartinez.net/delivery/ – free
I'm neither a Mac nor Webstorm user, but this might still be relevant.
For javascript I use the closure compiler as part of an upload script to minify. It doesn't monitor the files, it runs when I run the upload (a bash file).
If you wanted to keep it all in the IDE, it looks like Webstorm has an Ant plugin http://plugins.intellij.net/plugin/?webide&id=4526 that you could use to execute the closure compiler.
If you can find a command line css minifier then you could put that in the Ant script as well.
I use lessc and uglifyjs to concatenate and minify my css and js files. Here's a makefile from Twitter Bootstrap that I used a modified version of:
https://github.com/twitter/bootstrap/blob/master/Makefile
It's simple since all I do is type make in the command line whenever I want to compile.
I use Minify. It's on the Mac App Store.
I developed it to support my own workflow. minifyapp.com
I am new to Eclipse IDE, but now I need it to develop apps for webOS.
Help me please with the next questions:
I have downloaded the Eclipse IDE for JavaScript Web development. How can I find it's version information?
Can I use one instance of Eclipse IDE for JavaScript and C++ development at the same time? (if yes then please write the steps to extend JavaScript IDE to support C++ development) Or I should have two instances installed?
Some parts of documentation are written exactly for Eclipse Galileo C++ development. Are different versions of Eclipse IDE really different? Will I have problems porting settings from Galileo to Helios or Indigo?
Thanks.
Usually Versioninformation can be found under Help->About Eclipse
I do not know about this exact setup but I have Java/C++/PHP in one Eclipse install.
I installed the java version and then Help->Install New Software where I choose -all sites- as source and then searched for the compontent I wanted and installed it.
After installation restart eclipse to load the new plugins and now you should have a new Perspective for the language you installed.
If you can not find the perspective look under Window->Open Perspective->Other.
I do not know although I work with different version. Maybe some names (for example in menus) are changed but I really can't say (maybe a hint that they are not different? But Probably I just did not dive that deep into it).
The menu-paths I gave are under Indigo release.
I'm using Eclipse CDT with Aptana as a plugin which covers both bases for me.
How do I debug a Node.js server application?
Right now I'm mostly using alert debugging with print statements like this:
sys.puts(sys.inspect(someVariable));
There must be a better way to debug. I know that Google Chrome has a command-line debugger. Is this debugger available for Node.js as well?
node-inspector could save the day! Use it from any browser supporting WebSocket. Breakpoints, profiler, livecoding, etc... It is really awesome.
Install it with:
npm install -g node-inspector
Then run:
node-debug app.js

These use to work but are no longer maintained or no longer applicable to modern node versions.

The V8 debugger released as part of the Google Chrome Developer Tools can be used to debug Node.js scripts. A detailed explanation of how this works can be found in the Node.js GitHub wiki.
Node has its own built in GUI debugger as of version 6.3 (using Chrome's DevTools)
Simply pass the inspector flag and you'll be provided with a URL to the inspector:
node --inspect server.js
You can also break on the first line by passing --inspect-brk instead.
Node.js version 0.3.4+ has built-in debugging support.
node debug script.js
Manual: http://nodejs.org/api/debugger.html
Visual Studio Code will be my choice for debugging. No overhead of installing any tools or npm install stuff.
Just set the starting point of your app in package.json and VSCode will automatically create a configuration file inside your solution. It's build on Electron, on which editors like Atom are built.
VS Code gives similar debugging experience as you might have
had in other IDEs like VS, Eclipse, etc.
I personally use JetBrains WebStorm as it's the only JavaScript IDE that I've found which is great for both frontend and backend JavaScript.
It works on multiple OS's and has Node.js debugging built-in (as well as a ton of other stuff](http://www.jetbrains.com/webstorm/features/index.html).
My only 'issues'/wishlist items are were:
It seems to be more resource hungry on Mac than Windows It no longer seems an issue in version 6.
It would be nice if it had Snippet support (like those of Sublime Text 2 - i.e. type 'fun' and tap 'tab' to put in a function. See #WickyNilliams comment below - With Live Templates you also have snippet support.
A lot of great answers here, but I'd like to add my view (based on how my approach evolved)
Debug Logs
Let's face it, we all love a good console.log('Uh oh, if you reached here, you better run.') and sometimes that works great, so if you're reticent to move too far away from it at least add some bling to your logs with Visionmedia's debug.
Interactive Debugging
As handy as console logging can be, to debug professionally you need to roll up your sleeves and get stuck in. Set breakpoints, step through your code, inspect scopes and variables to see what's causing that weird behaviour. As others have mentioned, node-inspector really is the bees-knees. It does everything you can do with the built-in debugger, but using that familiar Chrome DevTools interface.
If, like me, you use Webstorm, then here is a handy guide to debugging from there.
Stack Traces
By default, we can't trace a series of operations across different cycles of the event loop (ticks). To get around this have a look at longjohn (but not in production!).
Memory Leaks
With Node.js we can have a server process expected to stay up for considerable time. What do you do if you think it has sprung some nasty leaks? Use heapdump and Chrome DevTools to compare some snapshots and see what's changing.

Theseus is a project by Adobe research which lets you debug your Node.js code in their Open Source editor Brackets. It has some interesting features like real-time code coverage, retroactive inspection, asynchronous call tree.
Node.js Tools for Visual Studio 2012 or 2013 includes a debugger. The overview here states "Node.js Tools for Visual Studio includes complete support for debugging node apps.". Being new to Node.js, but having a background in .NET, I've found this add in to be a great way to debug Node.js applications.
Visual Studio Code has really nice Node.js debugging support. It is free, open source and cross-platform and runs on Linux, OS X and Windows.
You can even debug grunt and gulp tasks, should you need to...
I wrote a different approach to debug Node.js code which is stable and is extremely simple. It is available at https://github.com/s-a/iron-node.
An opensource cross-platform visual debugger.
Installation:
npm install iron-node -g;
Debug:
iron-node yourscript.js;
I created a neat little tool called pry.js that can help you out.
Put a simple statement somewhere in your code, run your script normally and node will halt the current thread giving you access to all your variables and functions. View/edit/delete them at will!
var pry = require('pryjs')
class FizzBuzz
run: ->
for i in [1..100]
output = ''
eval(pry.it) // magic
output += "Fizz" if i % 3 is 0
output += "Buzz" if i % 5 is 0
console.log output || i
bar: ->
10
fizz = new FizzBuzz()
fizz.run()
If you are using the Atom IDE, you can install the node-debugger package.
Using Chrome Version 67.0.3396.62(+)
Run node app
node --inspect-brk=0.0.0.0:9229 server.js(server js filename)
Browse your app in chrome e.g. "localhost:port"
Open DevTools.
Click the the node icon beside the responsive device icon.
There will be another DevTools window that will pop out specifically for debugging node app.
There is built-in command line debugger client within Node.js. Cloud 9 IDE have also pretty nice (visual) debugger.
I put together a short Node.js debugging primer on using the node-inspector for those who aren't sure where to get started.
Visual Studio Code will work for us in debugging.
Use Webstorm! It's perfect for debugging Node.js applications. It has a built-in debugger. Check out the docs here: https://www.jetbrains.com/help/webstorm/2016.1/running-and-debugging-node-js.html
If you need a powerful logging library for Node.js, Tracer https://github.com/baryon/tracer is a better choice.
It outputs log messages with a timestamp, file name, method name, line number, path or call stack, support color console, and support database, file, stream transport easily. I am the author.
Assuming you have node-inspector installed on your computer (if not, just type 'npm install -g node-inspector') you just have to run:
node-inspector & node --debug-brk scriptFileName.js
And paste the URI from the command line into a WebKit (Chrome / Safari) browser.
Just for completeness:
The PyCharm 3.0 + Node.js Plugin offers an awesome development + run + debug experience.
Start your node process with --inspect flag.
node --inspect index.js
and then Open chrome://inspect in chrome. Click the "Open dedicated DevTools for Node" link or install this chrome extension for easily opening chrome DevTools.

There is the new open-source Nodeclipse project (as a Eclipse plugin or Enide Studio):
Nodeclipse became #1 in Eclipse Top 10 NEW Plugins for 2013. It uses a modified V8 debugger (from Google Chrome Developer Tools for Java).
Nodeclipse is free open-source software released at the start of every month.
There are many possibilities...
node includes a debugging utility
node-inspector
Code editors / IDEs (see debug instructions for one of the following)
Atom,
VSCode
Webstorm
and more
Debug support is often implemented using the v8 Debugging Protocol or the newer Chrome Debugging Protocol.
IntelliJ works wonderfully for Node.js.
In addition, IntelliJ supports 'Code Assistance' well.
The NetBeans IDE has had Node.js support since version 8.1:
<...>
New Feature Highlights
Node.js Application Development
New Node.js project wizard
