Funny flashback but the first thing that comes to mind is a take home programming challenge for a job interview.
If every candidate posted their react login code HN would have nothing else!

If it is a spin, the identity system used is a popular open source system which you can find at https://github.com/ory/kratos. The react code is a reference implementation of the same people who wrote that thing, and the article is intended to help people get started with the open source stack. So if you were indeed applying for a job interview, and the task would be to write such an app - you would know where to look. Plus, this would probably reduce the amount of terrible login solutions we have today in the WWW ;)
