Readme
Node.js function to invoke as the final step to respond to HTTP request.
This is a Node.js module available through the
npm registry. Installation is done using the
npm install
command:
$ npm install finalhandler
var finalhandler = require('finalhandler')
Returns function to be invoked as the final step for the given req
and res
.
This function is to be invoked as fn(err)
. 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:
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.res.statusMessage
is set according to the status code.env
is
'production'
, otherwise will be err.stack
.err.headers
object.The final handler will also unpipe anything from req
when it is invoked.
By default, the environment is determined by NODE_ENV
variable, but it can be
overridden by this option.
Provide a function to be called with the err
when it exists. Can be used for
writing errors to a central location without excessive function generation. Called
as onerror(err, req, res)
.
var finalhandler = require('finalhandler')
var http = require('http')
var server = http.createServer(function (req, res) {
var done = finalhandler(req, res)
