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.

Obviously, true developers prefer to return the date in a digital format, for example, '24.01.2024', '24-01-2024' and various combinations of this. But customers often want to work with human dates. In this post you can find how to return the custom localized date and how to use it with a Fluent-UI component DatePicker.

In apps with different Roles and permissions you may need to get information about AD Groups. Here are some snippets which can help you with this part of the task.

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.

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 I started to work with SPFX solutions for SharePoint, I couldn’t understand how to load external CSS files. I came up with one solution, but it was a crutch. I did it with embedding <styles> tag into JSX. It looked like this:

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.
