If `err` is falsy, the handler will -write out a 404 response to the `res`. If it is truthy, an error response will -be written out to the `res` or `res` will be terminated if a response has already -started. - -When an error is written, the following information is added to the response: - - * The `res.statusCode` is set from `err.status` (or `err.statusCode`). If - this value is outside the 4xx or 5xx range, it will be set to 500. - * The `res.statusMessage` is set according to the status code. - * The body will be the HTML of the status code message if `env` is - `'production'`, otherwise will be `err.stack`. - * Any headers specified in an `err.headers` object. - -The final handler will also unpipe anything from `req` when it is invoked. - -#### options.env - -By default, the environment is determined by `NODE_ENV` variable, but it can be -overridden by this option. - -#### options.onerror - -Provide a function to be called with the `err` when it exists.
