50 Useful JavaScript Tools


By Jacob Gube

JavaScript is a powerful client-side scripting language used in many modern websites and Web applications. In the hands of a skilled Web developer, JavaScript can enhance the user’s experience of the website and provide rich interactive components and features. But even though syntactically simple in nature, JavaScript is often difficult to author because of the environment it runs in: the Web browser. JavaScript’s popularity is evident in emerging technologies, such as Adobe AIR1, which use it as a supported language for creating desktop-based applications.

Below, you’ll find 50 excellent tools to help you achieve various tasks involved in authoring JavaScript code. You’ll find useful tools to speed up your coding processes, including debugging tools to hunt down places where your scripts break, unit testing and validation tools to test your scripts in various situations, security vulnerability scanners and code optimization tools to make sure your scripts are light as a feather.

You’ll also find a few new and alternative JavaScript and AJAX frameworks to help you explore options beyond the big names (i.e. MooTools, jQuery, YUI, Dojo, Prototype), in addition to useful scripts to help you accomplish a host of design and development tasks related to JavaScript.

    Great compilation, thanks! The new IE8 Developer Toolbar is much better now, and finally includes JavaScript debugging.

  2. 2

    Javascript! Run for the hills! That’s the way I’ve always felt about javascript. I just thankful that the syntax is nearly identical to PHP.

    Great roundup – javascript is a great language that allows you to add “something special” to a site. However, the important thing to remember is to keep the site functional before the addition of any scripts – they are mostly there for the visual impact.

  4. 4

    Javascript is great. It’d also be real cool to see some Adobe Flex stuff on SmashMag one day :)

  5. 5

    This is awesome! Tnx :)

  6. 6

    Also check out the Event Spy, Chickenfoot, iMacros, and Greasemonkey Firefox add-ons. There is an awesome script for Greasemonkey called XmlHttpRequestDebugging as well.

    Another lint program I found was JSON Lint.

    Other tools such as Sahi, Selenium (including the Firefox add-on IDE version), RBNarcissus, Watir / Watij / WatiN, and firewatir are great functional testing tools. Crawljax and CSpider.js are also worth a look for implemented crawling engines.

    JSSh, jasildbg, and JS Commander (jscmd) are additional debuggers.

    For security tools, you may want to list BeEF in addition to AttackAPI. The Technika project has some interesting features on top of Firebug. Other security-focused tools include ratproxy (from Google), and two tools from OWASP: Sprajax and Interceptor. There are also a few XML fuzzers such as untidy which may prove useful for security testing Ajax. A lot of potential comes way via the w3af attack tool, which currently supports DOM-based XSS testing, but will have even more future JS/Ajax/Flash/RIA security testing support.

    There are some nice Actionscript projects such as flash-thunderbolt which integrates with Firebug for when you’re debugging Flash applications and want to use something besides trace(). Web proxies such as Charles are also useful for Actionscript / AMF troubleshooting.

    Finally, in the commercial space I am aware of a few good tools. softwareverify.com has a Javascript Coverage Verifier. HP makes a tool called WebInspect (and QAInspect) which includes Ajax/Flash security scanning – as does IBM with their AppScan product. Fortify Software has Javascript security and lint-like features in their static-analysis tool. I’d avoid Fortify if you’re only going to use it for this purpose because it’s really only going to tell you to avoid eval(), setInterval() and setTimeout() or equivalents.

  7. 7

    Nice round up Jacob !!

    There are definitely useful items, I very much rely on Web Developer extension for Firefox & Firebug and would happily recommend it to any other web developer and designer.

    Although You missed many other great tools in this list like… Roar, Growl, Got API, SproutCore, The Regulator, Snippely, Google Mashup Editor, Beautify Javascript, ThemeRoller etc. etc..

    And finally… The one which i missing a most is “Greasemonkey”.

    Thanks anyway for your nice effort.

    DKumar M.

    Thanks for this great list.

  9. 9

    I’m still just a beginner, but I find Visual jQuery extremely helpful!

  10. 10

    Nice list, how no-one minds, I’ll pimp my own mocking framework on Google code: http://code.google.com/p/qmock (library agnostic but works best with Qunit). Just in case there’s any hardcore TDDers out there!

  11. 11

    Thnaks for this list.
    Maybe we can add LivePipe UI.
    LivePipe UI is a suite of high quality widgets and controls for web 2.0 applications built using the Prototype JavaScript Framework. Each control is well tested, highly extensible, fully documented and degrades gracefully for non JavaScript enabled browsers where possible. MIT licensed and actively maintained.

    Marvelous post :)

    I didn’t know Jx but I think it’s very useful. I found another Jx version for jQuery here.

    Btw. Drosera has been dead for more than a year now. It has been replaced, even in release versions of Safari, with the much more powerful Web Inspector. For more information, read the blog post: Web Inspector Redesign.

    Otherwise, a great list!

  17. 17

    Great list. Thanks!

  18. 18

    I also forgot to mention some trial tools such as Syhunt Sandcat Scanner Free edition and Acunetix WVS. AppScan and WebInspect are much better, but Syhunt and Acunetix have working trial downloads.

    Be sure to check out the Blueinfy tools – http://blueinfy.com/tools
    especially AppPrint and the scanweb2.0 tools! There are tools for Ajax/Flash fingerprinting, all written in Ruby, serving as great examples for testing purposes.

  19. 19

    That’s a very nice list! Thanks.
    As an addition to JavaScript authoring tools I’d mention DHX Toolkit (dhtmlx.com), they provide a set of nice-looking dhtml components, quite fast and easy to implement.

  20. 20

    Thank you very much!

  21. 21

    I use Regex Buddy for building complex expressions, it is a great time saver

    Another great resource, time to group all my [SM] bookmarks into a group. Hey .. when is there an article about that coming up ;)

  23. 23

    Good list – there’s a few in there I hadn’t heard about before.

    For documentation tools, I’d also add in Code Illuminated. Also written in JavaScript, it generates documentation on-the-fly – so no build step is required. It has an emphasis on typography, readability, and ease of use.

  24. 24

    ExtJS. http://www.extjs.com … enough said!

  25. 25

    great post
    companion js and the ie7-js
    seems so interesting to me

  26. 26

    Great Tips. Some well known others really cool to find out about

  27. 27

    Thanks for this useful tips!

    #2 > “I just thankful that the syntax is nearly identical to PHP.”
    $tmp = strpos($txt, ‘search’);
    looks like
    tmp = txt.indexOf(‘search’);
    Seriously, these two languages are completely different.

    I like that SM list, and use some of the tools listed above. Flot for instance, is really perfect and replaced my older Flash graphics for monthes, now.
    I still don’t get why a java programmer would use GWT : it seems much more complicated than any JS framework. Maybe because many Java programmers are scared of JS and refuse to learn how JS/HTML really work ?

  29. 29

    Javascript is pain in ass. Use Flex or Silverlight. Yes, there is possible to do all cool and rich interface application in javascript, but the effort is not worth it.

  30. 30

    Hey, great post thanks!

  31. 31

    the IE developer toolbar should be included in that list

  32. 32

    Thanks for the helpful feedback everyone.

    @Brian Gottier I wouldn’t say JS and PHP are identical, but they share a lot of similarities. The reason is they’ve both been influenced in some way by C.

    @Sven Eller While I agree with you in that JS can be a pain when it comes to cross-browser supported complex animations and effects, it’s got a few advantages over using Flex/Silverlight for web apps. I’m not disparaging those technologies you mentioned, they’re great, especially Flex, but I think there’s room for all and you’ve got to use what’s best for you and what’s best for what you’re doing.

    Javascript is garbage. It’s a huge kludge to help with the fiasco that modern web browsers have become. Stoooopid people have forced web browser (designed for document browsing) to be a place for running applications. Javascript running inside a browser is the the horrible bastard offspring of that movement.

    @Jack, almost all of the most recent important apps use JavaScript. Somehow the browser is doing enough right.

    @Jacob, thanks for the shotout. However, a big chunk of JavaScriptMVC’s awesomeness is how easily you can compress apps with it. Btw, It also includes a documentation engine now: http://javascriptmvc.com/wiki/index.php?title=Documentation_Overview.

    Oh, and your tests can run on the server in env. We are trying to release 1.5 tonight!

    When it comes to image manipulation in Javascript, nihilogic is the undisputed master. His image processing library, Pixastic, should definitely be listed here.

    HELP needed for one who just fell in love with javascript within html web pages utilized offline!!!
    I am sure everyone on this thread can answer my question!

    Calling OFFLINE files on local drive using window.setTimeOut to delay some calls. ISSUE: When I call a file w/o empty space in name, this function calls w/o errors on page, but I do not know how to do it when file has in its name.

    function runXZNNespritsPMz() {
    File=”E:\XZNNesprits\ZZ XZNNesprits PMz.session”;
    WSH=new ActiveXObject(“WScript.Shell”);

    I suspect your personal favourite is jQuery but it does seem odd to omit YUI from the “JavaScript/AJAX Authoring Tools” section. It is certainly capable of anything that jQuery is and probably has the richest set of features among all comparable offerings.

    Just came across this post. The tools presented are indeed worth recognition.

    I don’t usually write posts, but although this post is from last summer, I thought that this topic is very good (its good to have this info) and wanted to add my 2 cents…

    I use a very good tool for the creation of JavaScript menus called AllWebMenus which has proven to be very reliable and full of options.

    Apart from the program itself, what I like is that they keep up with developments. They have created solutions for different styles and types of menus, and even come out with jQuery based products for creating modal windows, tooltips, etc. which shows a broad comprehension of user’s needs.

    You can check them out at http://www.likno.com

    Hope this helps!

    Everyone who is involved in any kind of gaming, gambling, or betting as heard the stories of legendary people who have supposedly created the next foolproof betting system and have used the system themselves to help them to avoid losing and get higher profits over the long haul. The fact is that there is not a system in existence that can guarantee you that you will definitely be successful and never lose.

    nice compilation, however you don’t talk about code obfuscators/compressors. Let me introduce JSSOB : http://www.jssob.net/

    By the way, don’t forget great tools like

    – dean edwards packer : http://dean.edwards.name/packer/
    – Patrick J. O’Neil’s obfuscator : http://jsutility.pjoneil.net/

    Java should be forbidden ! Why someone coding nasty stuff for tamper users OS ! By no meanings no interaction with OS allowed by default ! Browsers aren’t secure and isolated either ! If one blocks it nothing works if not one is screwed by default ! The only solution is unblocked browser on some BSD rig isolated and only for internet browsing with no other documents on it ! They can hack copy or what ever they do to the system – it doesn’t mater ! But on win this is suicide ! Everybody on line wants to fuck everybody else thus so many problems !!!
