Optimus

UI layer on top of Asp.net Web Optimization framework for Umbraco, makes it possible to create script and style bundles from within the Umbraco backoffice.

For an intro to bundling and minification check out http://www.asp.net/mvc/tutorials/mvc-4/bundling-and-minification

In short: bundling and minification improves request load time by reducing the number of requests to the server and reducing the size of requested assets (such as CSS and JavaScript.)

Also possible to install providers for dynamic stylesheet and script support (less, sass, coffeescript, typescript).

For more details please check http://www.nibble.be/?p=238 and http://www.nibble.be/?p=237

For Umbraco 7.3 and higher please use the latest version, for older Umbraco versions use 1.3.2

Requirements

ASP.NET 4.5 Framework
Umbraco v6
Internet Explorer v9 + installed on web server (required by Less, CoffeeScript & TypeScript providers). You can use the V8 engine add on to avoid this dependancy.
TypeScript provider doesn't work correctly when used in IISExpress on Windows 8 (use full IIS instead).

Upgrading v1.2.1 to v1.3.0

Step 1: Uninstall any v1.2.1 Optimus Provider or AddOn (not the Core package) you have installed

Step 2: Install the v1.3.0 Optimus.Core package

Step 3: Install the v1.3.0 version of any Optimus Providers or AddOns you need

Upgrading v1.0 or v1.1 to v1.2.1 or v1.3.0

If you are using only the Core package then you can just install the latest version over the top of your current version, follow the below to ensure you don't loose your bundle definitions:

Step 1: Rename /App_Plugins/Optimus/config/bundles.config to temp.config

Step 2: Install v1.2.1 core package

Step 3: Delete bundles.config and rename temp.config back to bundles.config

Step 4: Restart your application pool

If you have providers installed, then all the providers have to be removed before upgrading the Core package and then the new versions of the providers can be installed. (v1.2.1 has provider uninstall support so that this process will be much easier for future versions)

(if you upgrading v1.2.0 to v1.2.1, then this isn't required, just install new versions over the top of the current version)

For each provider installed follow the below then upgrade the Core package as above.

Step 1: Remove the section element and all child elements with name that matches your provider from within /configuration/configSections/sectonGroup[@name="bundleTransformer"] of Web.Config

Step 2: Remove the http handlers for the provider you are removing from /system.webserver/handlers and /system.web/HttpHandlers

Step 3: Remove the provider from the bundleTransformer section, either in css or js sections depending on the type of provider

Step 4: Delete the BundleTransformer.[ProviderName].dll from the bin folder, e.g. BundleTransformer.Less.dll
