Summary

Cloudflare Workers offer a serverless execution environment that allows developers to deploy applications globally at the edge, enhancing performance and reducing latency by eliminating the need for server management. However, they are limited in their ability to run most server-side libraries and packages with dependencies not supported by Node.js, requiring bundlers like webpack for integration. For JWT verification within Cloudflare Workers, developers can choose between two libraries: cloudflare-worker-jwt, which is lightweight and optimized for use within the Cloudflare environment, and jose, which provides a broader range of cryptographic operations and is suitable for various environments. Both libraries require setting up a Cloudflare Worker and integrating the chosen library using a bundler. Developers must manage public keys and verify JWTs accordingly, with careful error handling and consideration for specific token claims to ensure robust authentication processes.
