Send is Connect's
static() extracted for generalized use, a streaming static file
server supporting partial responses (Ranges), conditional-GET negotiation, high test coverage, and granular events which may be leveraged to take appropriate actions in your application or framework.
$ npm install send
var send =
send(req, path, [options])
Create a new
SendStream for the given path to send to a
the Node.js HTTP request and the
path is a urlencoded path to send (urlencoded,
not the actual file-system path).
Set how "dotfiles" are treated when encountered. A dotfile is a file
or directory that begins with a dot ("."). Note this check is done on
the path itself without checking if the path actually exists on the
root is specified, only the dotfiles above the root are
checked (i.e. the root itself can be within a dotfile when when set
The default value is
'allow'No special treatment for dotfiles.
'deny'Send a 403 for any request for a dotfile.
'ignore'Pretend like the dotfile does not exist and 404.
Enable or disable etag generation, defaults to true.
If a given file doesn't exist, try appending one of the given extensions,
in the given order. By default, this is disabled (set to
example value that will serve extension-less HTML files:
This is skipped if the requested file already has an extension.
By default send supports "index.html" files, to disable this
false or to supply a new index pass a string or an array
in preferred order.
Enable or disable
Last-Modified header, defaults to true. Uses the file
system's last modified value.
Provide a max-age in milliseconds for http caching, defaults to 0. This can also be a string accepted by the ms module.

SendStream is an event emitter and will emit the following events:
erroran error occurred
directorya directory was requested
filea file was requested
headersthe headers are about to be set on a file
(res, path, stat)
streamfile streaming has started
endstreaming has completed
pipe method is used to pipe the response into the Node.js HTTP response
send(req, path, options).pipe(res).
By default when no
error listeners are present an automatic response will be made, otherwise you have full control over the response, aka you may show a 5xx page etc.
It does not perform internal caching, you should use a reverse proxy cache such as Varnish for this, or those fancy things called CDNs. If your application is small enough that it would benefit from single-node memory caching, it's small enough that it does not need caching at all ;).
