Its's more and more complicated to find information about SharePoint. I don't really know why it's so. That's why I often write down the references and examples. Today I tried to remember how to create a SharePoint list with PNPJS and there's a parameter which template you will use.

If you use a Pro version of Material UI, then you have a tool, how to switch the cells in the DataGrid table. But if you work with a wide table and you just want to make it more comfortable to work with it, there are some tricks for that. The first thing is to 'freeze' the header, so user can collate the column and headers. All the Excel users like this function. And the second thing is to allow user scroll the page if he has a small resolution and he doesn't have touch screen.

Obviously, it's an ordinary case, when you get an array of objects and you need to create for the reply the array of other Objects, but you need to initialize it on load. For React developers it can be often used with useEffect or componentDidMount.

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.

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.

Unlike classic Javascript applications, React works with Virtaual DOM, that’s why it’s not obviously how to add or remove class to the element. I will write about one of the ways how to make it.

We have an array of strings in React Application. Let's call it 'selectedParticipants'. And for the summary page we need to write all the members of array in one line with comma ',' between elements and dot '.' in the end in JSX block. Here is a small snippet.

Sometimes you need to get the parameters and values from the query string in your JavaScript/TypeScript applications. If you don't want to spend the time on making your own methods, you can use this one with URLSearchParams.

We have a string with an URL. And we want to get the host URL. I don't know about the built-in functions for this and I don't think that you should find external libraries for this. Although, it's a good idea to create your own personal class.

A JS/TS useful snippet to return only several last records with sorting by time. The data is stored in localStorage. I can't modify the types for external component, so that's why all the data has string types. and I use 'moment' to convert the strings to the date format.
