In the past decade we have seen massive changes in the way how web applications are developed. …
Create and edit online Excel files from your application
Microsoft’s Excel has been one the biggest applications to be ever released for business software. Even today, in a world with ‘big data’, ‘data lakes’ and more fancy buzzwords a lot of companies still primarily use Excel for their administration and Business Intelligence.

Make your React application part of the Microsoft 365 ecosystem
The Microsoft 365 platform has really taken of in the last decade with a lot of transitional enterprises finally moving their IT-landscape to the cloud. For developers this means that there is more and more value to be gained by integrating their applications with those cloud environments. …
Cross-Origin Requests are a part of the HTTP specification that has driven many developers to the limits of their sanity for how seemingly complex it is to make two websites talk with each other. In principle CORS actually exists to make this easier: it allows an opt-out for the same-origin…
In modern web development seeing data on websites update in realtime is very common. Look for example at the courier on the map of your Takeaway order or at the ETA on a track-and-trace page for the delivery of your new shoes. …
