/**
|
|
* Flexible error handler, providing (_optional_) stack traces
|
|
* and error message responses for requests accepting text, html,
|
|
* or json.
|
|
*
|
|
* Options:
|
|
*
|
|
* - `showStack`, `stack` respond with both the error message and stack trace. Defaults to `false`
|
|
* - `showMessage`, `message`, respond with the exception message only. Defaults to `false`
|
|
* - `dumpExceptions`, `dump`, dump exceptions to stderr (without terminating the process). Defaults to `false`
|
|
*
|
|
* Text:
|
|
*
|
|
* By default, and when _text/plain_ is accepted a simple stack trace
|
|
* or error message will be returned.
|
|
*
|
|
* JSON:
|
|
*
|
|
* When _application/json_ is accepted, connect will respond with
|
|
* an object in the form of `{ "error": error }`.
|
|
*
|
|
* HTML:
|
|
*
|
|
* When accepted connect will output a nice html stack trace.
|
|
*
|
|
* @param {Object} options
|

* @return {Function}
