I just bought WebStorm 5 and so far have been really enjoying its Inspection features. One hitch I've run in to when developing my Chrome extension is that it doesn't recognize the chrome variable:
Is there a way I can add the chrome variable to the Inspector so that it can autocomplete as I type? I'm guessing I would need to add Chromium as an External Library but I'm unsure where to start.
First Time Setup
Open the Settings dialog (File > Settings)
Click Languages & Frameworks > Javascript > Libraries
Click Download
Make sure TypeScript community stubs is selected
Select chrome from the list (you can find it quickly by just typing chrome)
Click Download and Install
Click OK to close the Settings dialog.
Steps 2-6 illustrated below:
In Subsequent Projects
In any subsequent project, you just:
Open the Settings dialog again (File > Settings)
Click Languages & Frameworks > Javascript > Libraries again
Check chrome-DefinitelyTyped
Click OK to close the dialog.
Steps 2-4 shown below:
UPDATE 2:
It's now supported out of the box, see the complete answer below.
UPDATE:
There is a more complete stub file that can be added as a library to get code completion. It's a part of the Closure Compiler project. Download chrome_extensions.js.
See also the feature request for WebStorm to add this library automatically from the IDE.
You need to get the JavaScript library for the Chrome API somewhere, or use a stub to get basic completion.
Library or a stub can be configured in WebStorm.
I found the JSON files with the Extension API. One can write a script that will build JS stubs from these JSON files, the stubs can look like the basic version linked on GitHub above, but with the automatic generation they will contain almost complete API and JSDoc comments so that documentation like here can be viewed directly in the IDE.
JSON => JavaScript object stubs mapping is pretty straightforward in this case and writing this kind of converter should not take more than a day (or several hours for the skilled coder).
If someone goes ahead and implements it, please post the link to the results here.
WebStorm should one day accept json definitions directly to enable autocomplete for the functions defined. Meanwhile, you can use the program at https://github.com/QuickrWorld/jsgen to convert the json files to js to enable auto-complete for the chrome extension APIs.
For writing AppScript, functions and classes such as DriveApp, SpreadsheetApp, there is a plugin in WebStorm or Intellij called google-app-script.
The installation method is the same as above. On the other hand, you should mark or open the .gs file as JavaScript. (July 2017)

I am looking for a vs code extension that auto creates the parameters for function as showed in the image attached. Is it part of vscode intellisense? For example when i type event listener i am hoping vscode would autofill parameters with something like addEventListener('type: DOMString', callback: EventListener
capture?: boolean)
At the moment I only get popup hints for vscode when I hover over the code.
The feature you're describing sounds like it could be the IntelliSense feature in Visual Studio Code. IntelliSense provides intelligent code completions based on the context of your code, and it can include parameter hints, which show the parameters that a function or method accepts when you're calling it.
In order to get this feature, you need to make sure that you have the correct language extension installed for the programming language you're using. For example, if you're working with JavaScript, you would want to install the "JavaScript (ES6) code snippets" extension.
You can install the JavaScript (ES6) code snippets extension from the Visual Studio Code marketplace by searching for it in the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on Mac) or by visiting this link:
https://marketplace.visualstudio.com/items?itemName=xabikos.JavaScriptSnippets
This extension should provide you with the parameter hints when you're typing the event listener and it's method.
Also, the feature can be improved by the fact that vscode have it's built in Intellisense which is pretty good and along with the above extension can work better to give you the autocomplete options and hints.
Please let me know if this helps or if you have any other question.
So. Dumb question.
I am using developer tools on chrome as essentially my IDE in the source tab. I have a JS file writing a program with no associated html/css files. Is there anyway for me to utilize the debugger for my JS file? Specifically I want to step into a function
In developer mode, select Sources tab, then navigate to your JS files in the left side. In the right panel, you can add a breakpoint to any line by pressing the line number which has a real js statement. Then you can run your application again to debug your js scripts.
The picture below is an example(Line 33 of assert.js is selected).
There are a number of different ways to debug/test your JS code, Chrome is only one of them.
QUOKKA
Quokka.js is a developer productivity tool for rapid JavaScript / TypeScript prototyping. Runtime values are updated and displayed in your IDE next to your code, as you type.
Runkit notebook
RunKit notebooks completely remove the friction of trying new ideas. With one click you’ll have a sandboxed JavaScript environment where you can instantly switch node versions, use every npm module without having to wait to install it, and even visualize your results. No more configuration, just straight to coding.
Hopa
Hopa is a zero config JavaScript/TypeScript runner right in your terminal.
JSComplete playground
This is a playground for JavaScript and React. You can use it to test simple code or prototype ideas. It requires a modern browser that understands ES2015 (ES6).
VSCode extensions Javascript REPL
Javascript REPL is a javascript playground for Visual Studio Code with live feedback(logs or errors) as you type, besides your code, in a log explorer, or in an output channel. It supports Javascript, TypeScript, CoffeeScript and it can be used for development in Node.js projects or with front-end frameworks like React, Vue, Angular, Svelte etc.
I found this question in stackoverflow, which is a bit similar but did not help me.
I would like to find some extension/plugin for vscode that would inject a JS and CSS code into a given URL.
For example, after setting a url in vscode, I create a js and when saving the file this script is injected into google chrome in the url mapped or in the tab that is open in chrome.
There is an extension to chrome that does just that: User JavaScript and CSS
This is non-trivial but definitely possible.
I sadly cannot provide you with all the necessary information as I am not sufficiently familiar with the way VSCode extensions function.
First of all, there is this project which you should take a look at. It's source code will have useful information.
Alternatively, and my personal recommendation, you should go with abusing the remote debugger which chrome provides. This project is a good example of how it can be used. It connects to the chrome remote debugger and exposes a REPL.
There is readily available documentation on how to use the remote debugger to execute arbitrary javascript.
The next part will be to make an actual extension which takes the above, ties it together and listens to a "on file save" event or something of the sort.
I'm using NetBeans for PHP.
When I edit a .js file, it gives me javascript code completion.
How can I get it to also give me jQuery code completion?
First go to Tools -> Options -> Miscellaneous and click on the Javascript tab,
make sure the targeted browsers are configured properly, code completion changes by the minimal version of the targeted browsers to make sure that the functionality is supported.
You also need to add the jquery js file to your project so netbeans would be able to parse it and to properly add code completion.
These answers are misleading because jQuery no longer self-documents using "scriptdoc." Version 1.1.4 was the last to have this. Anything newer than that (>=1.2 ~mid-2007) is gutted.
amending that: VSdocs actually work:
http://code.jquery.com/jquery-1.4.1-vsdoc.js
or http://www.asp.net/ajaxlibrary/cdn.ashx for version after 1.4.1
i suspect using a non-minified version of jquery would help.
For Netbeans 6.7 / 6.8 / 6.9, just follow the guide here:
Using jQuery to Enhance the Appearance and Usability of a Web Page
There's a section about half way down called "NetBeans Code Completion and API Support".
Worked no problem for me.
Note: "Choose the uncompressed version, i.e., 'Development', before downloading the jQuery library. Using the uncompressed version will allow you to examine the JavaScript code in the editor, and aid in any debugging processes."
Tip: Tools / Options / Miscellaneous / JavaScript. In the "Targeted Browsers" section, ensure IE is "6 or later". Otherwise, you'll get "Not supported" errors in the code completion pop-up and a lot of the commands will be struck out.
I use netbians 7.x for development on drupal 6.x. Autocomplete works after adding non-minified version jquery-1.2.6.js file to the root folder of the project (so it will be with any version).
It is important to specify the version of the file name, without -1.2.6 will not work!
The basic rule is that your jQuery (or for that matter any js lib) should be found in the same project you need auto complete to work. So just place jquery-1.x.y.js somewhere in your project (that can be reached by NetBeans as it reaches your js file) and you should be good to go.
To test you can put the jQuery file in the same folder as your js file being edited.
Make sure your Internet connection is working, because NetBeans downloads documentation when is needed. I think that NetBeans downloads it from there, but this is only my assumption. This is parsing friendly XML document with whole and recent jQuery documentation.
Most of my javascript work is done with Firebug and I feel annoying most of the times having to switch between the HTML mode and console mode (which again I split into output mode and input mode). When I switch to a different page to see the HTML and come back, I lose the code that I write. What is the best way to go about developing javascript applications using firebug?
Something like a mini IDE would be awesome: It just has to let me insert some code, examine the current page and then let me execute it. Any suggestions?
I use a simple text editor (vim) to write Javascript and HTML, and I check the result every now and then in Firefox. I have always two windows open: one for my text editor, and one with the current page open in Firefox. After saving a change in the Javascript, I switch to the browser and refresh the page to observe results. That was my workflow until recently.
A couple of weeks ago, I discovered the Combiner tool by Nicholas C. Zakas. To release my Javascript code, I am now using a complete build process based on Apache Ant, similar to what I was using while doing Java development previously.
The first step is to check the Javascript code with the JSLint tool by Douglas Crockford. I used to painfully copy and paste my Javascript code in the online version of the tool, once in a while; being able to run it on all my Javascript files at once with this Ant script is a huge convenience.
The second step is to combine all my Javascript files into a single file using the Combiner tool. The third step is to minify the Javascript code using YUI Compressor by Yahoo!. These last two steps allow to optimize the delivery of Javascript code to reduce page loading.
You can find an example Ant build file that you may adapt to your own needs. I am currently using this file to build my own Javascript library, bezen.org.
The other answers so far have been correct: I've never heard of anyone actually developing inside Firefox/Firebug, because it's a tool designed for debugging, not coding. To do your coding, you should use a tool designed for it (either a text editor or a full-fledged IDE).
But that being said, you might want to check out FireEclipse (Link). It will allow you to integrate Firebug with the Eclipse IDE (which itself has at least three different JS plug-ins to choose from). Alternatively I think the main (aka Web Standard Toolkit, aka WST) JS editor for Eclipse has some functionality which is similar to Firebug, but I've never used it so I don't know the details.
Hope that helps.
Write your HTML in an editor/IDE
Save your changes
Preview it in your browser
Debug using Firebug
Make your code edits in your SOURCE CODE
Repeat
Firebug is for debugging and allows you to do some "what if" fiddling while the page is live. This is not a replacement for an IDE.
