The SXA pipelines
Understanding how the pipelines and their processors work provides you with an insight into how dependencies are rendered, how tokens for rendering variants are created, how CSS classes are generated, and so on.
A pipeline consists of a sequence of processors. A processor is a .NET class that implements a method. When a pipeline is invoked, the processors are run in order. You can extend and customize the pipelines by adding or replacing processors. Extending a pipeline involves modifying the pipeline definition located in a Sitecore patch file.
decorateRendering
The decorateRendering pipeline is used to decorate the rendering's outer <div> tag with attributes. These can be standard attributes, such as id or class, but you can also add custom data attributes.
<div class="component title">

The getRobotsContent pipeline is used to extend the response provided to search crawler robots in the robots.txt file. The Robots.txt file is a simple text file on your site’s root directory that tells search engine robots what to crawl and what not to crawl on your site. The getRobotsContent pipeline contains the following processors:
|
