Configure the Smidge library for asp.net core

Scott Hanselman today blogged about Smidge. I think the library is pretty nice and I'm evaluating the library.

I like the option to define logic for Debug and Production like in the sample:

bundles.CreateJs("test-bundle-3", "~/Js/Bundle3")
   .WithEnvironmentOptions(BundleEnvironmentOptions.Create()
      .ForDebug(builder => builder
         .EnableCompositeProcessing()
         .EnableFileWatcher()
         .SetCacheBusterType<AppDomainLifetimeCacheBuster>()
         .CacheControlOptions(enableEtag: false, cacheControlMaxAge: 0))
      .Build()

However I couldn't find out what defines Debug/Production. Is there a way to tell the system when he's in debug and when he is in production mode?

Also seems that the Version can only be defined in the config.

"smidge": {
  "dataFolder" : "App_Data/Smidge",
  "version" : "1"
}

Is there an option do define the version in the code?

Solution

Is there a way to tell the system when he's in debug and when he is in production mode?

This is covered in the docs here: https://github.com/Shazwazza/Smidge/wiki/Rendering#debugging and it's based on the debug="true" attribute of the html tag.

Also seems that the Version can only be defined in the config.

The Version is controlled in Smidge by the Smidge.Cache.ICacheBuster. There are currently 2 implementations of this:

/// <summary>
/// Based on a static string specified in config
/// </summary>
public class ConfigCacheBuster : ICacheBuster

/// <summary>
/// Creates a cache bust value for the lifetime of the app domain
/// </summary>
/// <remarks>
/// Essentially means that all caches will be busted when the app restarts
/// </remarks>
public class AppDomainLifetimeCacheBuster : ICacheBuster

So it's possible to specify one of these or implement your own. If you implement your own, you need to add it to your container like:

services.AddSingleton<ICacheBuster, MyCacheBuster>();

Then you can specify options for your bundle (there are various ways to do this), for example:

bundles.CreateJs("test-bundle-2", "~/Js/Bundle2")
    .WithEnvironmentOptions(BundleEnvironmentOptions.Create()
            .ForDebug(builder => builder
                .EnableCompositeProcessing()
                .SetCacheBusterType<MyCacheBuster>())
            .Build()
    );

You can also see this startup class for examples: https://github.com/Shazwazza/Smidge/blob/master/src/Smidge.Web/Startup.cs#L126
