+
+Node.js function to invoke as the final step to respond to HTTP request.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install finalhandler
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var finalhandler = require('finalhandler')
+```
+
+### finalhandler(req, res, [options])
+
+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`.
+
+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. Can be used for
+writing errors to a central location without excessive function generation. Called
+as `onerror(err, req, res)`.
+
+## Examples
+
+### always 404
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  done()
+})
+
+server.listen(3000)
+```
+
+### perform simple action
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+```
+
+### use with middleware-style functions
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+var serve = serveStatic('public')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  serve(req, res, done)
+})
+
+server.listen(3000)
+```
+
+### keep log of all errors
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res, {onerror: logerror})
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+
+function logerror (err) {
+  console.error(err.stack || err.toString())
+}
+```

+HTTP status utility for node.
+
+## API
+
+```js
+var status = require('statuses')
+```
+
+### var code = status(Integer || String)
+
+If `Integer` or `String` is a valid HTTP code or status message, then the appropriate `code` will be returned. Otherwise, an error will be thrown.
+
+```js
+status(403) // => 403
+status('403') // => 403
+status('forbidden') // => 403
+status('Forbidden') // => 403
+status(306) // throws, as it's not supported by node.js
+```
+
+### status.codes
+
+Returns an array of all the status codes as `Integer`s.
+
+### var msg = status[code]
+
+Map of `code` to `status message`. `undefined` for invalid `code`s.
+
+```js
+status[404] // => 'Not Found'
+```
+
+### var code = status[msg]
+
+Map of `status message` to `code`. `msg` can either be title-cased or lower-cased. `undefined` for invalid `status message`s.
+
+```js
+status['not found'] // => 404
+status['Not Found'] // => 404
+```
+
+### status.redirect[code]
+
+Returns `true` if a status code is a valid redirect status.
+
+```js
+status.redirect[200] // => undefined
+status.redirect[301] // => true
+```
+
+### status.empty[code]
+
+Returns `true` if a status code expects an empty body.
+
+```js
+status.empty[200] // => undefined
+status.empty[204] // => true
+status.empty[304] // => true
+```
+
+### status.retry[code]
+
+Returns `true` if you should retry the rest.
+
+```js
+status.retry[501] // => undefined
+status.retry[503] // => true
+```
+
+## Adding Status Codes
+
+The status codes are primarily sourced from http://www.iana.org/assignments/http-status-codes/http-status-codes-1.csv.
+Additionally, custom codes are added from http://en.wikipedia.org/wiki/List_of_HTTP_status_codes.
+These are added manually in the `lib/*.json` files.
+If you would like to add a status code, add it to the appropriate JSON file.
+
+To rebuild `codes.json`, run the following:
+
+```bash
+# update src/iana.json
+npm run fetch
+# build codes.json
+npm run build
+```
