Deep Dives

From time to time I like to dive deep into various subjects. Every now and then I also produce a bloggable summary of my findings that I post here. I try to keep these posts up to date with the hopes that other people that need information on a subject won't have to spend as long researching. My deep dives are supported by web monetization, so if you use a service like Coil you have my gratitude.


I maintain a library for client-side validation and formatting of Swedish bank account numbers called kontonummer. In this deep dive I summarise how Swedish bank account numbers are formatted and what rules they follow.
