Wrapping JSON responses with dynamic callbacks at the edge allows for efficient content transformation and delivery. This reduces latency, enhances performance, and supports caching of both raw and transformed data, improving user experience and reducing load on the origin server.

Demonstrates how an EdgeWorker can wrap a JSON response with a dynamic unique callback function leveraging Response Provider and Stream API for efficient content transformation. The EdgeWorker should be enabled on JSON requests containing a callback query parameter, which can be managed via Property Manager. When such a request comes in, this EdgeWorker removes the callback query parameter, makes a sub-request to fetch the JSON data, and serves it as a stream. The EdgeWorker code adds a prefix with the callback function name captured from the query parameter and a suffix. Both JSON data and transformed data can be cached using standard ““Caching”” behavior in Property Manager if caching is allowed.
