Debugging Serverless Apps

In this blog post, the author demonstrates a technique for debugging serverless apps using Workers IDE. The approach involves returning debug information in a header and is applicable to both JavaScript and TypeScript. The author uses an interceptor pattern to execute code before and after a request, creating a LogInterceptor that adds all log lines to the X-Debug response header as a URL-encoded string if certain conditions are met. Finally, the post provides a Bash function for decoding the debug information returned in the header.
