Send is a library for streaming files from the file system as a http response
|
||||
supporting partial responses (Ranges), conditional-GET negotiation (If-Match,
|
||||
If-Unmodified-Since, If-None-Match, If-Modified-Since), high test coverage,
|
||||
and granular events which may be leveraged to take appropriate actions in your
|
||||
application or framework.
|
||||
|
||||
Looking to serve up entire folders mapped to URLs? Try [serve-static](https://www.npmjs.org/package/serve-static).
|
||||
|
||||
## 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):
|
||||
|
||||
```bash
|
||||
$ npm install send
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
var send = require('send')
|
||||
```
|
||||
|
||||
### send(req, path, [options])
|
||||
|
||||
Create a new `SendStream` for the given path to send to a `res`. The `req` is
|
||||
the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded,
|
||||
not the actual file-system path).
|
||||
|
||||
#### Options
|
||||
|
||||
##### acceptRanges
|
||||
|
||||
Enable or disable accepting ranged requests, defaults to true.
|
||||
Disabling this will not send `Accept-Ranges` and ignore the contents
|
||||
of the `Range` request header.
|
||||
|
||||
##### cacheControl
|
||||
|
||||
Enable or disable setting `Cache-Control` response header, defaults to
|
||||
true. Disabling this will ignore the `immutable` and `maxAge` options.
|
||||
|
||||
##### dotfiles
|
||||
|
||||
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
|
||||
disk. If `root` is specified, only the dotfiles above the root are
|
||||
checked (i.e. the root itself can be within a dotfile when set
|
||||
to "deny").
|
||||
|
||||
- `'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.
|
||||
|
||||
The default value is _similar_ to `'ignore'`, with the exception that
|
||||
this default will not ignore the files within a directory that begins
|
||||
with a dot, for backward-compatibility.
|
||||
|
||||
##### end
|
||||
|
||||
Byte offset at which the stream ends, defaults to the length of the file
|
||||
minus 1. The end is inclusive in the stream, meaning `end: 3` will include
|
||||
the 4th byte in the stream.
|
||||
|
||||
##### etag
|
||||
|
||||
Enable or disable etag generation, defaults to true.
|
||||
|
||||
##### extensions
|
||||
|
||||
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 `false`). An
|
||||
example value that will serve extension-less HTML files: `['html', 'htm']`.
|
||||
This is skipped if the requested file already has an extension.
|
||||
|
||||
##### immutable
|
||||
|
||||
Enable or disable the `immutable` directive in the `Cache-Control` response
|
||||
header, defaults to `false`. If set to `true`, the `maxAge` option should
|
||||
also be specified to enable caching. The `immutable` directive will prevent
|
||||
supported clients from making conditional requests during the life of the
|
||||
`maxAge` option to check if the file has changed.
|
||||
|
||||
##### index
|
||||
|
||||
By default send supports "index.html" files, to disable this
|
||||
set `false` or to supply a new index pass a string or an array
|
||||
in preferred order.
|
||||
|
||||
##### lastModified
|
||||
|
||||
Enable or disable `Last-Modified` header, defaults to true. Uses the file
|
||||
system's last modified value.
|
||||
|
||||
##### maxAge
|
||||
|
||||
Provide a max-age in milliseconds for http caching, defaults to 0.
|
||||
This can also be a string accepted by the
|
||||
[ms](https://www.npmjs.org/package/ms#readme) module.
|
||||
|
||||
##### root
|
||||
|
||||
Serve files relative to `path`.
|
||||
|
||||
##### start
|
||||
|
||||
Byte offset at which the stream starts, defaults to 0. The start is inclusive,
|
||||
meaning `start: 2` will include the 3rd byte in the stream.
|
||||
|
||||
#### Events
|
||||
|
||||
The `SendStream` is an event emitter and will emit the following events:
|
||||
|
||||
- `error` an error occurred `(err)`
|
||||
- `directory` a directory was requested `(res, path)`
|
||||
- `file` a file was requested `(path, stat)`
|
||||
- `headers` the headers are about to be set on a file `(res, path, stat)`
|
||||
- `stream` file streaming has started `(stream)`
|
||||
- `end` streaming has completed
|
||||
|
||||
#### .pipe
|
||||
|
||||
The `pipe` method is used to pipe the response into the Node.js HTTP response
|
||||
object, typically `send(req, path, options).pipe(res)`.
|
||||
|
||||
## Error-handling
|
||||
|
||||
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.
|
||||
|
||||
## Caching
|
||||
|
||||
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 ;).
|
||||
|
||||
## Debugging
|
||||
|
||||
To enable `debug()` instrumentation output export __DEBUG__:
|
||||
|
||||
```
|
||||
$ DEBUG=send node app
|
||||
```
|
||||
|
||||
## Running tests
|
||||
|
||||
```
|
||||
$ npm install
|
||||
$ npm test
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Serve a specific file
|
||||
|
||||
This simple example will send a specific file to all requests.
|
||||
|
||||
```js
|
||||
var http = require('http')
|
||||
var send = require('send')
|
||||
|
||||
var server = http.createServer(function onRequest (req, res) {
|
||||
send(req, '/path/to/index.html')
|
||||
.pipe(res)
|
||||
})
|
||||
|
||||
server.listen(3000)
|
||||
```
|
||||
|
||||
### Serve all files from a directory
|
||||
|
||||
This simple example will just serve up all the files in a
|
||||
given directory as the top-level. For example, a request
|
||||
`GET /foo.txt` will send back `/www/public/foo.txt`.
|
||||
|
||||
```js
|
||||
var http = require('http')
|
||||
var parseUrl = require('parseurl')
|
||||
var send = require('send')
|
||||
|
||||
var server = http.createServer(function onRequest (req, res) {
|
||||
send(req, parseUrl(req).pathname, { root: '/www/public' })
|
||||
.pipe(res)
|
||||
})
|
||||
|
||||
server.listen(3000)
|
||||
```
|
||||
|
||||
### Custom file types
|
||||
|
||||
```js
|
||||
var extname = require('path').extname
|
||||
var http = require('http')
|
||||
var parseUrl = require('parseurl')
|
||||
var send = require('send')
|
||||
|
||||
var server = http.createServer(function onRequest (req, res) {
|
||||
send(req, parseUrl(req).pathname, { root: '/www/public' })
|
||||
.on('headers', function (res, path) {
|
||||
switch (extname(path)) {
|
||||
case '.x-mt':
|
||||
case '.x-mtt':
|
||||
// custom type for these extensions
|
||||
res.setHeader('Content-Type', 'application/x-my-type')
|
||||
break
|
||||
}
|
||||
})
|
||||
.pipe(res)
|
||||
})
|
||||
|
||||
server.listen(3000)
|
||||
```
|
||||
|
||||
### Custom directory index view
|
||||
|
||||
This is an example of serving up a structure of directories with a
|
||||
custom function to render a listing of a directory.
|
||||
|
||||
```js
|
||||
var http = require('http')
|
||||
var fs = require('fs')
|
||||
var parseUrl = require('parseurl')
|
||||
var send = require('send')
|
||||
|
||||
// Transfer arbitrary files from within /www/example.com/public/*
|
||||
// with a custom handler for directory listing
|
||||
var server = http.createServer(function onRequest (req, res) {
|
||||
send(req, parseUrl(req).pathname, { index: false, root: '/www/public' })
|
||||
.once('directory', directory)
|
||||
.pipe(res)
|
||||
})
|
||||
|
||||
server.listen(3000)
|
||||
|
||||
// Custom directory handler
|
||||
function directory (res, path) {
|
||||
var stream = this
|
||||
|
||||
// redirect to trailing slash for consistent url
|
||||
if (!stream.hasTrailingSlash()) {
|
||||
return stream.redirect(path)
|
||||
}
|
||||
|
||||
// get directory list
|
||||
fs.readdir(path, function onReaddir (err, list) {
|
||||
if (err) return stream.error(err)
|
||||
|
||||
// render an index for the directory
|
||||
res.setHeader('Content-Type', 'text/plain; charset=UTF-8')
|
||||
res.end(list.join('\n') + '\n')
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### Serving from a root directory with custom error-handling
|
||||
|
||||
```js
|
||||
var http = require('http')
|
||||
var parseUrl = require('parseurl')
|
||||
var send = require('send')
|
||||
|
||||
var server = http.createServer(function onRequest (req, res) {
|
||||
// your custom error-handling logic:
|
||||
function error (err) {
|
||||
res.statusCode = err.status || 500
|
||||
res.end(err.message)
|
||||
}
|
||||
|
||||
// your custom headers
|
||||
function headers (res, path, stat) {
|
||||
// serve all files for download
|
||||
res.setHeader('Content-Disposition', 'attachment')
|
||||
}
|
||||
|
||||
// your custom directory handling logic:
|
||||
function redirect () {
|
||||
res.statusCode = 301
|
||||
res.setHeader('Location', req.url + '/')
|
||||
res.end('Redirecting to ' + req.url + '/')
|
||||
}
|
||||
|
||||
// transfer arbitrary files from within
|
||||
// /www/example.com/public/*
|
||||
send(req, parseUrl(req).pathname, { root: '/www/public' })
|
||||
.on('error', error)
|
||||
.on('directory', redirect)
|
||||
.on('headers', headers)
|
||||
.pipe(res)
|
||||
})
|
||||
|
||||
server.listen(3000)
|
||||
```
