Workers Context (ctx)
Explains how to use the Context API in Cloudflare Workers to manage lifecycle events via waitUntil and passThroughOnException, and how to pass authenticated configuration data between workers using ctx.props.
When To Use
Use when you need to extend a worker's lifecycle to complete background tasks or when you need to pass trusted configuration data between workers using service bindings.
