Custom Rendering Variant Token Tool for SXA

Sitecore Experience Accelerator (SXA) provides a great way to alter how components render using a feature called Rendering Variant. The following post describes how I developed a new Rendering Variant tool that implements NVelocity templates. I found a way to extend a feature built into the great SXA.

For those that have not yet worked with NVelocity, it's essentially a mechanism for converting tokens into other text. This is often used in Sitecore standard values where you use $name to populate the title field.

UPDATE: SXA comes with some tools that you can take advantage of right now called $dateTool and $numberTool. Read more about them here and here.

Problem Statement

Marketing would like to have the page Url output in the website global search results.


As you can see above, the rendering shows a title, description, and url. Unfortunately  I was not able to figure out how to do this OOTB with SXA. Fortunately it took very little effort to write code for this.

Setup

There are a few steps you need to take in order for this to work.
  1. Have a need for it. Duh.
  2. Setup a Visual Studio project, something like Company.Foundation.Variants.
  3. Reference the SXA library Sitecore.XA.Foundation.Variants.Abstractions.dll, Sitecore.Kernel.dll, and Sitecore.NVelocity.dll.
  4. Add a new class to define the tool, such as Company.Foundation.Variants.NVelocityExtensions.LinkTool.
  5. Add a new class to register the tool, such as Company.Foundation.Variants.Pipelines.GetVelocityTemplateRenderers.AddTemplateRenderers.
  6. Patch the new pipeline in to getVelocityTemplateRenderers.
Here's a little snippet to get you started.

Usage

In the Rendering Variant configured for search results, add a VariantTemplate item. The template field should then contain something like the following:

<a href="$linkTool.GetItemLink($item)">$linkTool.GetItemLink($item,true)</a>

Here is the html set within the VariantTemplate.


That's pretty much all there is to setting it up. Hope you find this feature as helpful as I did!

Unicorn Serialization for SXA Projects

Sitecore Experience Accelerator (SXA) is organized in a way that aligns with Sitecore's Helix design principles and conventions. The following post describes how I structured a solution with Unicorn serialization to allow for low complexity management.

I'll try to explain as much as I can using pictures; everyone likes pictures.

Organizational Structure

The following names will be used to organize code and serialized content.
  • Feature
  • Foundation
  • Project
  • Website


Starting from the bottom I have a project using the naming convention [COMPANY].Website. This project contains code and configurations needed to bootstrap a website that would keep it in an operational state. Changes to Sitecore.config would appear as patch-configs in this project.

Let's have a look at this node expanded.



Example:
The configuration Company.Serialization.config contains all of the root items necessary for Unicorn to work in the solution. I've sanitized the example to use the generic name Company


Now let's have a quick look at some of the places where those items are in the Sitecore tree. The company name here is Concentra.


The configuration file is designed to create all of those root items. When a new developer joins, he/she will want to sync the Company.Website configuration first so all these root nodes appear.

Example:
The configuration Company.Project.DotCom.Serialization.Dev.config contains all of the descendant items that are project specific, such as site templates. This config contains the settings necessary for TransparentSync.

When you create a new tenant and site with the SXA wizard (powered by Sitecore PowerShell Extensions!) you will want to use the structure Tenant Folder > Tenant > Site (i.e. Concentra > DotCom > usa). I like this pattern because you future-proof the structure to support multiple companies.
You will want to use this configuration on your developer machine. Everything is tracked and transparently synced.

Example:
The configuration Company.Project.DotCom.Serialization.Cm.config contains the same as before, but disables TransparentSync and uses exclusions. You will want to use this configuration on Content Management environments, the primary reason is because the Home and Data trees should not be overwritten; Marketers will want to punch you if you do.

Putting it all together

So let's recap what we have.
  • Visual studio projects for Website, Project, Foundation, and Feature.
  • Unicorn serialization configurations that capture root nodes for the company (Website) and then other configurations for the tenant and site (Project). Foundation and Feature work the same way but have no information about the tenant/site.
  • Unicorn serialization configurations take into account what developers want to capture and own versus what should be deployed to other environments.
  • Unicorn files and configurations are removed before each deployment to ensure renamed or unused files are removed.
Here's a short video to add more detail.Thanks for watching!
