Previously worked about webmarkupmin

I should also note - this works in DEV, but not in PROD. And yes, I have everything set to configure for usage, no matter the environment. There weren't any new "server" requirements, were there?

Hello, Christopher!

Are you using the following settings?

    …
    public class WebMarkupMinConfig
    {
        public static void Configure(WebMarkupMinConfiguration configuration)
        {
            configuration.AllowMinificationInDebugMode = true;
            configuration.AllowCompressionInDebugMode = true;
            …

It is also possible that errors occur when parsing HTML content. I recommend you to write your own logger or use the built-in logger (ThrowExceptionLogger class). If you use ASP.NET Web Forms, then the logger for WebMarkupMin needs to be registered in the App_Start/WebMarkupMinConfig.cs file as follows:

using WebMarkupMin.Core.Loggers;
…
DefaultLogger.Current = new ThrowExceptionLogger();

Hello, Christopher!

Did my advice help you?

[christopherdude]

Thank you for your patience! In using your method of throwing an exception, this is what came through: {"Category: JS_MINIFICATION_ERROR\r\nMessage: Expected '(': {\r\nFile: /\r\nLine number: 772\r\nColumn number: 19\r\nSource fragment:\r\n\r\nLine 771: }\r\nLine 772: catch {\r\n-----------------------------^\r\nLine 773: //debugger;\r\n\r\n"}

By commenting out the following line, everything seems to work..

DefaultJsMinifierFactory.Current = new MsAjaxJsMinifierFactory();

Hello, Christopher!

Category: JS_MINIFICATION_ERROR
Message: Expected '(': {
File: /
Line number: 772
Column number: 19
Source fragment:

Line 771:             }
Line 772:             catch {
-----------------------------^
Line 773:                 //debugger;

It seems that JS minifier perceives the catch block without a exception value as syntax error.

It expects instead of this line:

    catch {

Expects the following line:

    catch (e) {

If you are using the WebMarkupMin.MsAjax or WebMarkupMin.Yui module, then replace it with a more modern module - WebMarkupMin.NUglify:

[christopherdude]

Will do - thanks for the fast reply. I'm actually using the latest 2.14.0 from NuGet. Does that not have that latest module?

[Taritsyn]

After installing the WebMarkupMin.NUglify module, this line:

DefaultJsMinifierFactory.Current = new MsAjaxJsMinifierFactory();

Need to be replaced with the following line:

DefaultJsMinifierFactory.Current = new NUglifyJsMinifierFactory();

[Taritsyn]

I'm actually using the latest 2.14.0 from NuGet. Does that not have that latest module?

Microsoft Ajax Minifier and YUI Compressor for .NET libraries have been deprecated.

It looks like you are using a WebMarkupMin.MsAjax module. Uninstall the WebMarkupMin.MsAjax package and then install the WebMarkupMin.NUglify package. Replace the corresponding namespaces and update the code as in the previous post.

[christopherdude]

That did it! Thank you so much. By the way, do you have a minification setting in here for *.svg?

[Taritsyn]

The WebMarkupMin does not have an SVG minifier.

If SVG code is embedded in HTML code, then it is minified according to rules similar to XML minification.

For individual .svg files, you can use an XML minifier (embedded scripts and styles will not be modified). But .svg files are static files and the WebMarkupMin.AspNet4.WebForms module will not work for them. For static files, you will need a WebMarkupMin.AspNet4.HttpModules module with XmlMinificationModule and may require special IIS configuration.
