Injecting Resources into Experience Editor in Powerful Ways

I recently got a ping back from Eric Stafford on an old blog article of mine, the first one I had ever posted! He was working on some code and needed to inject in some custom CSS into the Experience Editor. We had several conversations on Slack, and I thought I’d post up some powerful ways in which to achieve this. Be sure to check out Eric’s posts, he’s done a fair amount of research into different ways of achieving this as well.

Harden Security for your Sitecore Client Applications

tl;dr; Ensure you include an Assert.CanRunApplication(“/path-to-application”) check in your custom application to enforce security

Have you created any customs application in Sitecore? Do you use Sitecore Roles to restrict access to those applications?

Often only certain roles should have access to certain pieces of functionality, which is fairly standard requirement, and a common way to restrict access to applications is to remove Read access to the item in the Core Database.

Take for example default out of the box Sitecore applications such as the Indexing Manager. Your average author really should not have access to this more developer centric functionality. And if they did, then nothing too bad could happen, they’d just be able to kick off the re-indexing process. Nothing too bad, but it would be both unexpected and use up server resources for no particular reason.

Helix: Patching your Config Patches for Specific Environments

Following a conversation on the #helix-habitat channel over on Sitecore Slack Chat a few days ago, I thought it would be worth penning a quick post…

A question was asked about “How to organise your CM vs CD config in a Helix Solution”. This was about configs in your specific implementation, not the default Sitecore configs that need to be enabled or disabled for a specific Sitecore environment.

For example, you may have some specific custom pipelines or event handlers that should only run on the CM instance.

Some suggested that these custom configs should be enabled/disabled/modified as part of the deployment process using PowerShell, possibly using an XML file which provides a mapping of files for the environments. This could then be maintained by the developers.

I suggested a different approach, and “tagging” your config nodes to make them easier to patch… The approach was new/unknown to some so I thought I would (re)blog it.

Setting up Azure CDN to deliver your Sitecore Media

At SUGCON EU 2016 I presented about the different options of using Content Delivery Networks with Sitecore. At the time, I had been working on a particular task to offload large media items into Azure Blob storage and serve them to via Azure CDN and wrote a number of posts detailing how I achieved this.

One of the options that I presented was utilising Azure CDN to serve your media, allowing you to benefit from Azure’s Geo-located Edge Servers meaning that assets are served from locations closer to your users, your own servers can focus on just delivering content (possibly meaning less content delivery servers and licensing costs) as well as improving browser response times by domain sharding the requests.

Use of Azure CDN will work with any version of Sitecore, and is not specific to Sitecore 8.2 Update-1 which added Azure Web Apps support. In fact, you don’t even need to be hosting your servers in Azure to utilise the CDN service.

I’ve been asked by several Sitecorians about configuring CDN, so I thought I would share a step-by-step guide in setting up Azure CDN with Sitecore.

Rolling back your TDS deployments (and Sitecore Upgrades)

Have you ever had the need to rollback your Sitecore deployments? Or maybe an upgrade went wrong and you need to rollback the changes?

Well you should’ve taken proper backups then, shouldn’t you! Learn your lesson yet? Now go back and add proper back-up steps to your deploy process… Good. Jeez. Shortest blog post ever! Moving on…

The problem with backups is it takes time, which seems to exponentially increase as your Sitecore database increased in size, and an equally heap load of time when you need to restore that database. The other problem with the backup is that it is just a point of time restore, what about changes that have happened since that backup had taken place?

Highlight Sitecore Components with Rendering Chrome

a.k.a “Rendering Wrappers”

tl;dr; MVC HTML Helper and custom CSS styling to add chrome highlighting around renderings in Experience Editor mode.

I presented this module at the Sitecore User Group London on 12th January 2017. You can download the slides for that lightning talk here.

A few months ago I presented Session 4 of the Unofficial Sitecore Training sessions that Akshay “Be My Friend” Sura and Mike “Blog All The Things” Reynolds have been hosting. If you’re new to Sitecore or need a refresher course then I suggest you head on over and watch the videos on the series, there’s some really useful info in there from some seasoned Sitecore developers and gurus.

Anyhow, I decided presenting stuff and virtually pointing things out is hard so I added a fairly early version of some code that we had been using and experimenting with on our current project. This would make it easier to see components in Experience Editor mode and therefore easier for the audience to follow along with what I was doing. Some people noticed this at least 🙂

Environment Styler for Sitecore

tl;dr; Install the module, set the config value to match your environment, have a stylised login screen and header bar per environment.

Have you ever sat there working on some task and then suddenly someone asks you to take a look at an issue on the Production environment? So you log onto that server, resolve the issue, get distracted for a few minutes by cat videos and then get back to what you were doing. But you suddenly realise that those changes you were just making was not on your local environment, you still had the Production site open in your browser tab! Oh noes!

Oh noes!

The problem is that all the environments all looks exactly the same… the only difference being that teeny tiny URL bar, the URL in which probably also looks very similar apart from some environment prefix.

Custom Post Install Steps – Installing Sitecore from a Clean Slate Using SIM

A question popped up on Sitecore StackExchange asking how to remove the default items when installing using SIM. As we all know, Sitecore installs some sample items and provides the “lady with the phone” sample homepage. Normally I just ignore them, the items will be there in the deployed solution but since they are not referenced anywhere we don’t really care.

Anyway, there are no steps in SIM to clean the default items from the install of Sitecore. I’ve previously blogged about running scripts using PowerShell and TDS Post Deploy actions, but that requires SPE to be installed and the scripts to be deployed but TDS generates .update packages so that would be no good to install with SIM. However Sitecore packages themselves can contain Post Install Steps, they are not TDS specific – post install steps are used as part of the upgrade process or when installing packages such as WebForms For Marketers for example.

So why not create a custom package with a Post InstallStep to delete the default (or any) items?

Goodbye z.Last – Custom Sitecore Config Patch Folder

I’ve previously written a couple of blog posts about Organising your Sitecore Patch Include Files and the subsequent Re-organisation of Include Config Patch files in Sitecore 8. As mentioned in that blog post, in order to ensure that our custom configs are patched in last we can place our own files in /App_Settings/Include/z.Project. I also raised a Sitecore userVoice request to add additional folder locations for patching.

Recently when providing an answer on Sitecore StackExchange about alternative ways of disabling config files and taking a peek inside the Sitecore.Kernel to post some code for the answer I noticed something…

If you looked at the code snippet in my original post then you would have noticed that the method was private static 😥

Something had changed…

TDS Post-Deploy PowerShell Step

I’ve recently been spending some time to upgrade our solution as well as perform some tweaks, optimizations and clean up on our deployment process. Even though I am the creator of UniCorn, I’ve almost exclusively been using Team Development for Sitecore in all the projects which I have worked on 🐘

The release of TDS 5.5 allowed developers to add their own custom deploy steps. Previously these might have been conducted manually (urgh!) or we had deployment steps added to our process in Octopus Deploy to conduct these. The post deploy steps however are better since they can be developer controlled and added to source control. Win!

The Hedgehog Team has been asking for the community to share their post deploy scripts. You can find a number of scripts here. There are some great scripts there, similar to what we currently have. But the way that script are added and managed in the TDS projects was a bit annoying to me…

So it got me thinking about that great quote by J.R.R. Tolkien:

One Script to rule them all, One Script to find them,
One Script to bring them all and using SPE bind them

One Script To Rule Them All
