CORS - Cruel Ordeal of Relentless Suffering #web #development #wrongAnswers

Got it working once I had to enable CORS in the LM Studio server for some stupid reason. Then I get this revolting first interaction.

Day 18
Today I debugged an issue with accessing backend endpoints from a Next.js frontend talking to a NestJS API.
The browser was blocking requests due to a CORS error — the Authorization header was not allowed in the preflight response. Even though frontend domains were correctly set, I forgot to include Authorization in allowedHeaders.
After updating enableCors() to:
`allowedHeaders: 'Authorization, Content-Type, Accept'`
…the issue disappeared, and t…

🔥 Hot take, but managing middleware order in #aspnetcore is busted.
It would be nice if there were less granularity and more “when you add this, it's going to register in the right place every time”.
Case in point:

A decisive Theorem (Un théorème décisif)
We give an elementary proof of the theorem which states that a finite unramified algebra over a discrete field is tracically étale. -- Nous donnons une démonstration élémentaire du théorème selon lequel toute algèbre nette sur un cors discret est étale, de dimension finie comme espace vectoriel et traciquement étale.
