brings in new capabilities

Thank You!

No more LESS support in the latest version. But "LESS" is there on the product page, there's even a LESS-settings tab in the options. Thanks for ruining our work process.

This extension is #1 result in Google for "Visual Studio LESS".

PS. the new "ASP.NET and Web Tools 2012.2" only highlights LESS code, but does not compile it!! So your answer does not help!!

Amazing extension!

by Richard D | December 19 2013

Nice tools, but unfortunately Typescript is left out of the recent update. So a lot of the functionality I used is not available anymore.

:-(

Unfortunately, VS Express doesn't support 3rd party extension. It's not a limitation of Web Essentials

Dropping support for TypeScript (without plastering that "little" detail all over the download page) has just cost me 4 wasted hours and sent me full circle back to the old Web Essentials.

1. Installed Web essential update
- lost TypeScript support

2. Installed separate TypeScript add-in from MS
- Does not build existing TypeScript files in project

3. Researched how to modify project to get it to build TypeScript files
- Still does not build existing TypeScript files in project

4. Created a new project minimal testbed to test TypeScript compiling
- ts files are added, with TypeScriptCompile option, but do not generate .js files at all. Tools | Options etc have no effect

5. Researched this new problem
- Gave up in disgust

6. Uninstalled TypeScript & latest Web Essentials

7. Installed old Web Essentials
- Luckily this was still in my download folder

8. Have now lost color-coding, intellisense and all those other features that made Web Essentials useful.
- Decide to write grumpy review :(

I have never had so much grief from one update. In future I will Google for problems with the updates before even thinking about pressing upgrade!

WebEssentials 2012 is a stellar extension. Being able to collapse JavaScript between {curly brackets} is very useful.

by Ytrog | October 15 2013

Good plugin although the CoffeeScript functionality doesn't compile the scripts and crashes vs2012 every time I try :(

by Aleksandar Totovic | October 08 2013

It's very nice

      I actually have all the compilers (LESS, TypeScript, JSHint CoffeeScript) turned off.

    • I just updated today (8/27/2013) to version 3.0 and I am now getting the same HRESULT: 0x80070057 (E_INVALIDARG) error in my build output. It is not preventing my solution from building though, thankfully.

  • LESS calc() compilation bug
    2 Posts | Last post August 20, 2013
    • the LESS compiler will generate:
      
      width: -moz-calc(80%) !important;
      width: -webkit-calc(80%) !important;
      width: calc(80%) !important;
      
      when given:
      
      width: -moz-calc(100% - 20px) !important;

    • Problem here too
  • TypeScript comments no longer hiding
    1 Posts | Last post August 13, 2013
    • Anyone know why the typescript comments are no longer hiding from the JS on save.  Also the keep comments flag is gone.  If web essentials no longer is compiling it, how do I tell VS to remove them?
      
      Thanks!
  • About JsDoc of Web Essentials 2012
    1 Posts | Last post August 08, 2013
    • i saw that  Web Essentials 2012 has support for jsDoc intellisense, but I can't seen any options for enabling it, and it doesn't appear to do anything.
  • cant use &:after anymore in less
    1 Posts | Last post August 05, 2013
    • hi, 
      with 2.9 the compiler gives error when using  &:after{} in less
  • Uncaught Error: undefinedModule in V2.9
    3 Posts | Last post August 05, 2013
    • Why my project throw "Uncaught Error: undefinedModule " and "Uncaught ReferenceError: exports is not defined " errors in V2.9? I use dojo with AMD mode. In the old version it's ok, but in the new version I even can't open the project after save code with the configuration " Compile TypeScript on save".  
    • my TypeScript version is 0.8.2
    • I changed to nightly version, and it works fine.
  • jshint ignores references
    1 Posts | Last post August 03, 2013
    • When i have a VS reference to another JS file,
      
      /// <reference path="../Entity.js" />
      
      , then JSHint will just ignore this and say "JSHint: 'Entity' is not defined." when i use that entity in my file.
      
  • Less and relative to root paths.
    1 Posts | Last post August 01, 2013
    • Hi, just wondering, upgraded to 2.8.1 and still got a problem with compiling less to css.
      @import "/Content/css/bootstrap/bootstrap.less";
      Will yield an error: LESS: '/Content/css/bootstrap/bootstrap.less' wasn't found (404)
      File with import is in /Content/css. We've been using those paths to be able to reorganize without problem. 
      Have been and is working fine using the client side less compiler. Noticed it a couple of days ago when we started to look into compiling css on build.
      Is this something that could be fixed for Web Essentials 2012?
      
  • TypeScript 0.9.0.1
    1 Posts | Last post July 31, 2013
    • Compiler is hanging in 0.9.  Any plans to fix this?  
      Thanks.
