Cloudflare Workers used for GraphQL server deployment and CDN services

Developers are increasingly utilizing Cloudflare Workers to build production-ready GraphQL servers. Recent updates to the platform, specifically the support for connections over TCP, allow for direct database connections, addressing a previous limitation where developers often had to rely on PostgREST APIs or external services like Supabase.

In a related application, the GraphQL schema registry Hive uses Cloudflare Workers and R2 storage to function as a highly available CDN for GraphQL schema artifacts. This setup ensures that mission-critical artifacts, such as Schema Definition Language (SDL) and Supergraphs, remain accessible to GraphQL Gateways even during console incidents. To enhance security, Hive implemented a system for generating and invalidating dynamic CDN access tokens, moving away from static keys to prevent unauthorized access in the event of a leak.
