I would previously have rated this 5 stars, but this latest version runs
the "linter" on every build, which basically kills my development
environment on any project of any size. There does not appear to be a
way to prevent it from running on minimized files.

You can turn this behavior off in the options, otherwise I would have to
disable this extension entirely.

Freezes Visual Studio completely when I have knockout attributes in the HTML.. Have to terminate VS and restart over and over again.. The web essentials is disabled until this is fixed.. I really hope you work on this.

Very useful features to Visual Studio for web developers

This extension made typescript far more accessible. I look forward to SCSS support!

Hi, excellent tool. highly appreciated. but it extremely slows done while you are writing JS code. you need to work on it.

P.S: that dude seems to be jealous through out the video when you are presenting your plugin.

I am downloading and installing this for the collapsible code brace region feature. if (stateMentTooLong){... I want to collapse it now without regions....}

but lo! that feature is not working in my VS2010.

This add-in is great in VS2012, except for one problem: most of the time when I try to save a .coffee file that has syntax errors, Visual Studio crashes. Let me know if there is any info I can send to help you debug this.

Fantastic addition to Visual Studio!

It become unusable when editing medium-large javascript files... about a second delay from keypress to character appearing in the document! I had to disable it... when bugs like this dissapear, I'll give another try.

Really great ideas, but JS extensions are way too slow and seem to compete with MS JS extensions, which are better. Can you add the ability to selectively enable/disable the tools? That might be a huge improvement. The CSS extensions are awesome, but I can't leave this thing running because it kills the JS editor.

  • Mindscape Web Workbench and the color preview has issues
    6 Posts | Last post September 23, 2013
    • I'm using Mindscapes Web Workbench for SASS editing and have discovered a conflict with Web Essentials in the latest release. In version 2.0.451 they have added outlining to the SASS editor and the color preview causes a lot of flickering when I edit (basically syntax highlighting is turned on and off for large parts of the code). It mostly seems to happen after the first preview, but in one instance it happened after the second preview. If I turn of outlining Ctrl-M, Ctrl-P it behaves much better (seems to still be an issue with comment highlighting).
      Is there any way I can turn off the color preview feature?
    • No, you cannot turn features on/off in Web Essentials yet. 
    • Do you have any fix for this? It's rather annoying
    • Any progress on this? With every key I press in an SCSS file, the code jumps all over the place as the color swatch seems to be refreshing. It's pretty annoying, and sadly I end up disabling the extension. Is this a Web Essentials problem or a Mindscape issue?
    • I would like to ask when will be some way to turn off some of the features?
      Right now the best js collapse extension is JSEnhancements. The collapsing Web Essentials does is not correct. All other functions are great. If Web Essentials can't collapse the js code like JSEnhacements, at least would be nice to turn that collapsing feature off and the two extensions could live together.
    • I'm having this same issue - a feature is conflicting with another extension, and I would like to just turn off that feature (CSS color preview).
  • Too many false positives
    1 Posts | Last post September 13, 2013
    • WE is great.. but
      Using VS2013 Rc I am getting too many false positives. 
      In js its telling me that variable is defined but never used, but is used in another script or in say a ajaxForm success call.
      In css its telling me heaps of rules are unused when they are used.
      This makes a huge unmanageable list of warnings
  • Less errors vs warnings
    1 Posts | Last post September 06, 2013
    • When I open a less-file, WE automatically tries to compile it, and therefore any errors in the compilation is added to the error list. Since I haven't initiated the compile myself, I think that the result of the "helpfull" compile should just be warnings, if anything. 
      When I do compile/save the file, it is fine to add the results to the error list.
  • Error Writing File
    1 Posts | Last post July 31, 2013
    • I have been getting this error while working with TypeScript files in VS 2012.  I have options to generate js turned on.  As soon as I make an edit to .ts file and hit save, the error "Error writing file" comes up in the js window.  Workaround includes checking out all ts/js files or just turn on the option to build all ts files during project build.
      Any chance for this to be fixed?
      Thank you.
  • box-shadow
    1 Posts | Last post July 24, 2013
    • Why when I create a style with box-shadow and add vendor specif items through the little snippet only -webkit-box-shadow is added? Why isn't the -moz-xxxx added?
  • JSHint ignores
    1 Posts | Last post July 23, 2013
    • I'm using the RaphäelJS library on my project and JSHint issues too many errors for this library.
      I've tried to create a .jshintignore on my project, without any success.
      There is some way to ignore certain .js files from JSHint build validation?
      Any chance to make .jshintignore to work?
      My .jshintignore:
  • absolute paths
    1 Posts | Last post July 05, 2013
    • why doesn't @import work right with absolute paths?
      in my root .less file I have:
          @import "/Content/bootstrap/less/reset.less";
      but in the error list it says:
          Error 31 LESS: Couldn't load Content/bootstrap/less/reset.less (404) ...
      NOTE the lack of a leading '/' - it got removed.
  • Some of the features are not reflecting
    1 Posts | Last post July 01, 2013
    • Hi,
      Some of the features are not working as they are described especially the region option in Vb and Javascript functions collapsing
  • Coffee script crashing VS2012 Professional
    1 Posts | Last post May 06, 2013
    • I opened a website (File > Open > Website) from a local directory. Then added new CoffeeScript file using new file dialog (Ctrl+N). The new coffeescript editor is opened with preview split screen.
      Then pasted this coffee code in it http://pastebin.com/Hzt4gBtE. Once pasted, I clicked in preview screen (for JS), I got the shutting-down error.
      Please review this issue. I just updated to v2.7.. 
      Please also bring the CoffeeScript and other filetypes in new file dialog when no project or website is opened (open a new instance of VS and press Ctrl+N). 
      PS Its a shame that we don't have support for SCSS and SASS!
  • import file returns 404
    3 Posts | Last post April 18, 2013
    • Hi,
      I've started facing an issue after I upgraded to version 1.6 where the @import url('../../../settings.less'); stopped working and I see the following error in the output window 
      Error	1	LESS: Couldn't load ../settings.less (404)
      Is this a known issue? Is there a workaround?
      Thank you,
    • I've encountered the same issue as Guy. @import statements in .less throw compile errors on save if a relative path '../mycss.less' is used.
    • We have run into the same issue here. It definitely seems to deal with paths. Any files which only reference files in the same directory work fine.
