HOW WE MADE BILLING BACKENDLESS

Summary from the TLDR Web Dev newsletter

Autumn tried to simplify billing by handling payments directly on the frontend. Its initial approach was to use a "publishable key," but it was limited and confusing. Next, it experimented with Next.js server actions, which were insecure due to the exposure of customer IDs. To address this, it implemented a custom encryption layer for server actions, which finally allowed secure operations from the frontend.
