SXA : Disabling asset optimizer not working

1 comment
I’ve previously blogged about disabling Sitecore SXA asset optimizer. Recently, I’ve stumbled upon a situation where we have disabled SXA asset optimizer for SXA site in non-production environment but CSS styles and javascripts are still getting rendered in minified version - optimized.min.js and optimized.min.css.

I’ve made sure that asset optimizer was disabled for local SXA site. For troubleshooting, I’ve also disabled asset optimizer at global level but I have no luck. I’ve verified value of XA.Foundation.Theming.StylesConfigurationId and XA.Foundation.Theming.ScriptsConfigurationId settings and these settings were having correct value assigned.

XA.Foundation.Theming.StylesConfigurationId : The ID of the item that stores the configuration for style asset optimization. 
(/sitecore/system/Settings/Foundation/Experience Accelerator/Theming/Optimiser/Styles)
<setting name="XA.Foundation.Theming.StylesConfigurationId" value="{B3B10434-DACE-483E-B375-49C6D215723D}" />

XA.Foundation.Theming.ScriptsConfigurationId : The ID of the item that stores the configuration for script asset optimization.
(/sitecore/system/Settings/Foundation/Experience Accelerator/Theming/Optimiser/Scripts)
<setting name="XA.Foundation.Theming.ScriptsConfigurationId" value="{4110D103-861E-464F-A258-130A8FCF4C61}" />
Then I’ve peeked into source code of Sitecore.XA.Foundation.Theming.dll and checked implementation of AssetConfigurationReader.
public virtual AssetConfiguration ReadConfiguration()
    {
      AssetConfiguration assetConfiguration = new AssetConfiguration();
      Item designItem = ServiceLocator.ServiceProvider.GetService<IPresentationContext>().DesignItem;
      if (this.RequestAssetsOptimizationDisabled)
        return new AssetConfiguration()
        {
          ScriptsMode = AssetServiceMode.Disabled,
          StylesMode = AssetServiceMode.Disabled,
          RequestAssetsOptimizationDisabled = true
        };
      if (designItem == null)
        return assetConfiguration;
      bool? tristate1 = this.ParseTristate(designItem.Parent[Sitecore.XA.Foundation.Theming.Templates._Optimizable.Fields.StylesOptimisingEnabled]);
      bool? tristate2 = this.ParseTristate(designItem.Parent[Sitecore.XA.Foundation.Theming.Templates._Optimizable.Fields.ScriptsOptimisingEnabled]);
      assetConfiguration.ScriptsMode = this.GetConfiguration(designItem.Database.GetItem(ID.Parse(Settings.GetSetting("XA.Foundation.Theming.ScriptsConfigurationId"))));
      assetConfiguration.StylesMode = this.GetConfiguration(designItem.Database.GetItem(ID.Parse(Settings.GetSetting("XA.Foundation.Theming.StylesConfigurationId"))));
      if (tristate1.HasValue)
        assetConfiguration.StylesMode = !tristate1.Value ? AssetServiceMode.Disabled : AssetServiceMode.ConcatenateAndMinify;
      if (tristate2.HasValue)
        assetConfiguration.ScriptsMode = !tristate2.Value ? AssetServiceMode.Disabled : AssetServiceMode.ConcatenateAndMinify;
      return assetConfiguration;
    }
This code has pointed me to right direction. It seems that designItem was set to null. I’ve opened content editor and navigated to context page item in content tree. In the Designing section, Page Design field value was empty.


I’ve selected appropriate Page Design, saved my changes and published the sitecore item. Voila! Asset optimizer gets disabled and uncompressed CSS styles and javascripts start getting render. Comments and suggestions are most welcome. Happy coding!

Sitecore SXA : Disable Asset Optimizer

Leave a Comment
Asset Optimizer is a good feature of Sitecore SXA as it improves the end user experience by minifying CSS styles and javascripts thus reducing the amount of data that needs to be transferred over HTTP request.  If Asset Optimizer is enabled, then Sitecore will automatically generate optimized.min.js and optimized.min.css. It is recommended to enable Asset Optimizer for production environment but sometimes you need to disable Asset Optimizer in non-prod environment (DEV, QA or STAGING) to troubleshoot or debug website scripts and css styles. In this blog post, I am doing to show few ways to disable Sitecore SXA Asset Optimizer:

Disable the Asset Optimizer globally

You can disable Asset Optimizer at global level for all SXA sites. In the Sitecore Content Editor, navigate to /sitecore/system/Settings/Foundation/Experience Accelerator/Theming/Optimiser and for both Scripts and Styles sitecore items select Mode as Disabled to disable Asset Optimizer. Save and publish your changes.

Disable asset optimizer for a specific SXA site

You can disable Asset Optimizer for a specific SXA site. In the Content Editor, navigate to /sitecore/content/…/SXA_SITE_NAME/Presentation/Page Designs. In the Asset Optimization section, in the Styles Optimizing Enabled and Scripts Optimizing Enabled fields set field value as NO to always disable optimization for SXA site.

Disable asset optimizer temporarily for a specific sitecore page

Even with the Asset Optimizer enabled, you can temporarily disable the assets optimisation on any Sitecore page. All you need to do is pass aodisabled=1 as query string parameter to your request url. For example: https://local.mysxaplayground.net/viewlocations?aodisabled=1
It is best practice to disable the Asset Optimizer in non-production environments and to enable it in production environments.
Comments and suggestions are most welcome. Happy coding!

Sitecore experience commerce 9 – No Sitecore Commerce Engine log files?

Leave a Comment
Recently while working with Sitecore experience commerce 9, I’d encountered few issues. To resolve those issue, I need to check logs. While troubleshooting I have found that there were no Sitecore commerce engine log files in log folder. I’d recycle application pool and even restarted IIS but no luck. I’d started troubleshooting with config. json file located at C:\inetpub\wwwroot\CommerceAuthoring_Sc9\wwwroot\ and Bingo! I’d hit the nail right on the head. I’ve compared config.json with default Sitecore.Commerce.Engine config.json file and found out that logging configuration section was missing in config.json. I’ve added below configuration in config.json, given write access on log folder to NetworkService account and application pool identity user (CSFndRuntimeUser), restarted IIS and log files started updating in log folder. I’ve done similar steps for CommerceMinions, CommerceOps and CommerceShops websites.
"Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Information",
      "System": "Warning",
      "Microsoft": "Warning"
    },
    "ApplicationInsightsLoggingEnabled": false
  },
  "Serilog": {
    "Using":  ["Serilog.Sinks.Literate", "Serilog.Sinks.File"],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Information",
        "System": "Information"
      }
    },
    "FileSizeLimitBytes": 100000000
  }
Comments and suggestions are most welcome. Happy coding!

I was able to resolve this issue by making below changes in powershell script (Deploy-Sitecore-Commerce.ps1)
  • Set value as CommerceServicesDbServer = "." instead of CommerceServicesDbServer = "./"
  • Set value as SitecoreDbServer = "." instead of SitecoreDbServer = "./"
You may have to update above DbServer values as per your SQL Server configuration. Comments and suggestions are most welcome. Happy coding!

Getting started with Sitecore Rocks

This year, I had received opportunity to present at Sitecore NCR user group. I’d presented on extension for Visual Studio - Sitecore Rocks. Sitecore Rocks makes Sitecore developers happy. Sitecore Rocks is free, and it is useful for many other Sitecore development tasks. Here is the recording and slides of this session:
