Express Mung

Overview

The express-mung package is a middleware for modifying express responses synchronously and asynchronously. It allows transformation of the response in LIFO order, similar to how request middleware works in Express. The package is implemented by hooking into the response methods like res.end, res.json, or res.write.

Features

• Transform JSON Body: Modify the JSON body of the response using synchronous or asynchronous functions.
• Transform HTTP Headers: Modify the HTTP headers of the response.
• Abort Detection: Automatically abort when a response has been sent to prevent further processing.
• Exception Handling: Catch and handle exceptions to send proper HTTP error responses.
• License: Released under the MIT license by Richard Schneider.

Summary

The express-mung package provides a flexible middleware solution for modifying Express responses in various ways. It offers features like transforming JSON bodies, modifying HTTP headers, detecting response completion to prevent errors, and handling exceptions gracefully. This middleware can be useful for scenarios where customization or processing of responses is required in an Express application.
