Everybody loves User Custom Actions in SharePoint. That’s the only recommended way of customizing SharePoint. You have heard about it. Unfortunately there is no convinient way of administering them. People have their console applications or powershell scripts to add, update and delete user custom actions. It works but it is hard to open up Visual Studio or PowerShell every time you will try out an idea on a test site. To overcome this, I have created a tiny little tool, packaged as a bookmarklet for your browser. When you click on it, it will show your existing user custom actions and you can add new user custom actions. It is an ongoing little project, available on github, contributions are welcome. What’s left is:

I have a newer blog post about MDS, that provides a much simpler solution. Please check it before reading further.

This is a part 1 of the blog post about Minimal Download Strategy and javascript adjustments for user code. What I initially thought should be enough for one post, is not enough, so I see it as a part 1. I wrote this post after I had read Chris O’Brien’s post about JSLink Here I want investigate how we can get his accordion list view working with MDS. Minimal Dowload Strategy or MDS is a new feature in SharePoint 2013. By now, if you read this post, you already know about it. The simplest way to see if MDS is enabled on your site, you can recognize it on the “ugly” urls. I don’t think they are so ugly. But it is a matter of taste and habit. No matter if you like MDS or not, MDS is enabled on many site templates and is a huge step towards a faster, more responsive architecture in SharePoint, I would say, towards the Single Page Application concept in SharePoint (but it is a long way to go). We have to keep the MDS in mind, when we write our customizations in javascript. SharePoint 2013 loves javascript and the probability is high that you write a lot of javascript. If it doesn’t work with MDS, your code breaks and the user doesn’t see the functionality, or the site owner must disable the Minimal Download Strategy feature. I wouldn’t like to have disabling of an improvement feature as a prerequisite for my code. In this blog post I want to dig into the techniques for getting the javascript code working with MDS. For a while ago I read a wonderful blog post in Chris O’Brien’s blog:

Om det inte passar att javascript i masterpage eller egen webpart, registrera det som customaction och aktivera feature. Läs mer här. Här är ett exempel:

<CustomAction 
		Location="ScriptLink"
		ScriptSrc="~sitecollection/\_layouts/MyProject/awesome.js"
		Sequence="101">
</CustomAction>
