SharePoint Framework is growing fast and is doing well. With Field Customizer you can build an own rendering for columns in views like you used to build in CSR with JSLink. So there is an guide by Microsoft how to migrating your CSR applications into SPFx applications. It makes sense using this guide, because the Modern UI does not support CSR. The only struggle I had: Some CSR applications are rendering more than one column. So here is the topic of this post: How to build a SPFx Field Customizer Solution with multiple columns.

Standards are good and sometimes you want some standards in SharePoint Online. A useful tool is the Content Type Hub. You should know it from SharePoint 2010 and 2013. Whenever you need it, you can create one, by activating the Site Collection Feature "Content Type Syndication Hub". This feature allows you to publish your Site Columns and Site Content Types to every other site Collection. So you might thing you can build your hub in SharePoint Online by activating the feature on a new Site Collection. If you do so you will get an error. It tells your proxy is not working correctly, but this is not true. In fact there is already an hub and you cannot build a second one. The hub is hidden so you cannot see it in the Site Collection Overview in your admin center. You need to know the URL: https://yourprefix.sharepoint.com /sites/contenttypehub  

It is a while since Microsoft launched the Add In (or App) architecture for SharePoint, but there are still things they change or we are not familiar with. In August 2016 there was a change in giving tenant permissions to provider hosted Add Ins using app-only mode and Azure Access Control Service (ACS).
