Debug Error Middleware

debug-error-middleware, currently at version 1.3.0 (last published 7 years ago), provides a development-focused error handling middleware for Express and Koa applications. Its primary function is to display detailed context information, including stack traces and object internals, in the response to failed requests. This is invaluable for debugging during development, offering insights into errors that would typically be suppressed or logged without immediate feedback to the client. A key differentiator is its automatic source map support, making transpiled code errors easier to interpret, though this can be disabled. The package's most critical aspect is its explicit and enforced prevention of use in production environments, as it leaks sensitive system information, making it solely a development utility. Given its last update date, the project appears to be abandoned.
