Angular NgPlural Directive for Localization

February 22, 2017 by Chris Sherman

The Angular ngPlural directive adds or removes DOM templates based on a numeric value. It comes in handy when you’re doing localization (l10n) to adapt your content to meet the language and cultural requirements of a specific market.

When you want to use the plural rules, enter the plural category in the ngPluralCase directive. When you want an exact match, such as “4” in the example below, use the equal sign before the value in the ngPluralCase directive.

Wait for Data Before Rendering Views in Angular 2

Minification and Bundling in Umbraco

December 16, 2014 by Chris Sherman

The Microsoft ASP.NET Web Optimization Framework improves the performance and reliability of your application through bundling, minification and versioning of your web resources. Bundling multiple scripts or stylesheets into one resource saves overhead by requiring browsers to make fewer HTTP requests; minification entails shortening the variable names and eliminating whitespace in your resources, thereby reducing file size; appending a version to your bundles ensures visitors to your site will use the current resources rather than stale, cached versions with the same file name.
