Support for SharePoint Server 2019 officially ends on Tuesday, July 14, 2026. That’s less than six months away — and for many organizations, this date is approaching faster than expected. SharePoint 2019 has been a stable and reliable on-premises platform for years, but the end of mainstream support is an important milestone that should not be ignored.

In this post I will tell you how to upgrade the version of the SPFX framework of the existed solution. Here is the information only about SharePoint online, because for SharePoint 2019 On-premises you can use only NodeJs 10 and spfx 1.4.0.

This post is about how to crate a list item in SharePoint list in backend process. It can be API, background service, azure function, mobile or desktop app. So, it can be anything you want, but in .Net. And we will use SharePoint Rest API, that is wrapped by CSOM (Microsoft.SharePointOnline.CSOM).

At my previous job I was happy to work with SharePoint on-premises. More than 10 years with SP 2007, 2010 and finally 2019. Almost 3 years ago I thought I won't cooperate with it. In May 2026 the support of SharePoint server ends. But as it turned out many companies still use SP on-prem and don't want to migrate.

When you are developing a workflow for multiple users and roles, at least sometimes you must check your app with different accounts. When you use Chrome or Edge, it's not obvious how to switch account in SharePoint on-premises. When you click a button 'Sign out', it automatically logs in with you active account.

To update the Created Field for SharePoint list item you can start the script like this. The most important here is the 'fullcontrol' permissions and '-UpdateType UpdateOverwriteVersion' parameter in the request.

For a process I had to update the Author field in SharePoint online list item. This time I decided to use PnP.Core instead of PnP.Framework. Was it worth it? I don't really know, but the method is not the most difficult part of the task.

Here I will write down the steps for creating projects for SPFX solutions. The prerequisites - Node, Yo and spfx-fast-serve are already installed.

I used Material UI DataGrid (@mui/x-data-grid": "^7.12.1") in SharePoint spfx webpart solution. Obviously, that wasn’t a good decision, but too much was already done.

In this post you I will write how to get available options from the SharePoint field 'Choice'. I often use it, and sometimes I need to use it in customizations or reports.
