I had a SharePoint online list and I added a new column into it. And then I wanted to work with a data, which is close to be real. So I needed to generate the data and insert it into the list. For the tasks like this I like to use division by module to create semi-random data.

How to store credentials? It’s always a question because nobody wants to demonstrate the passwords, neither for the databases, nor for web services or anything else. SharePoint has a built-in tool to store a sensitive data – technical user accounts, databases or any data like this.  Here is how to create variables in the secure store.

Class to determine if a user is in the SharePoint group or is in the AD Group, which is added to the SharePoint group. So, the admin access to a custom SharePoint module is that everybody, who exists in the admin group, has more data. The admin group is a SharePoint group, which contains SPUsers (from domain) and Domain groups, which contain AD Users. Actual for SharePoint 2016, 2019.

While the development SPFX for SharePoint 2019 once the loading of the webpart at 'workbench.aspx' page stopped. SharePoint server is installed at my virtual machine, the development of SPFX is local. At first I totally could not understand what's wrong. But soon started to look for the reason.

When you make a SharePoint 2019 on-premises solution, you can make not only SPFX solutions, but also old-school WSP-solutions. It allows you not only to use SharePoint API, but also to use your own API services. With SharePoint 2019 you can use WCF service. For example, it’s a good way when you develop an application which uses the external database. This works also for SharePoint 2013 and SharePoint 2016.

If you want to get the Author login from the SharePoint object, for example, list item, you should use 'expand=Author' in the query. It's necessary, but not sufficient. There's one more option, which you must use.

Icons make a better view to any application. And for a developer it’s always a problem to find how to use Icons and especially where to find them. If you work with SharePoint Online solutions, this will help you (and also me) to find a place of icons and how to use them. As far as I often work with FluentUI, the post is about it.

I developed a service for SharePoint 2019 (on premise) and this service should move files from document library to an external storage. The client part is made with SPFX solution – command set. It added buttons to the interface of the document library.

When you are developing SPFX application for SharePoint online, you use a page https://{sharepoint_url}/sites/{some_subsite}/_layouts/15/workbench.aspx. For non-fullwidth webparts it fits normally, but if you need to create a wide or full-width webpart, it's not very comfortable.

While writing the script to create lists for my solution for SharePoint Online I had to rename Title field in a list. It's not so obviously as just to create a new field.
