  res.end("users")
}))
app.addRoute("/posts", cors(function (req, res) {
  res.end("posts")
}))
app.addRoute("/api", Corsify({
  "Access-Control-Allow-Methods": "POST, GET, PUT, DELETE"
}, function (req, res) {
  res.end("api")
}))

http.createServer(app).listen(8000)

Documentation

Corsify(opts: Object, handler: (req, res)) => (req, res)

Corsify can be called with options

var opts = {
    // if this is set to false then preflight `OPTIONS` is
    // not terminated
    endOptions: Boolean,
    // if you want to compute the allowed origin manually you
    // pass in a getOrigin function
    getOrigin: (req, res) => String,
    // these are default header values you can set. Corsify
    // has sensible defaults. You can't use Allow-Origin and
    // getOrigin at the same time.
    "Access-Control-Allow-Origin": String,
    "Access-Control-Allow-Methods": String,
    "Access-Control-Allow-Credentials": String
