Tj Holowaychuk eb88f160b6 Added support for routes to handle errors. Closes #809
currently only the route end-point callbacks
support this, however this will change in the near future
to support route middleware etc
2011-08-17 14:33:11 -07:00

this will allow you to essentially "trick" the express
app into thinking it is mounted when it is not.

not sure why we had this, ive never even used it

Tj Holowaychuk d54ee58f93 Added support for multiple callbacks for app.param(). Closes #801
you can also make several calls to `app.param()` for the same
param name, which is equivalent to passing multiple in
a single call

Fast, unopinionated, minimalist web framework for [node](http://nodejs.org). [![Build Status](https://secure.travis-ci.org/visionmedia/express.png)](http://travis-ci.org/visionmedia/express)
```js
var express = require('express');
var app = express();

# Express
Insanely fast (and small) server-side JavaScript web development framework
built on [node](http://nodejs.org) and [Connect](http://github.com/senchalabs/connect).
var app = express.createServer();
app.get('/', function(req, res){
res.send('Hello World');
});
app.listen(3000);

## Philosophy
Via Connect:
The Express philosophy is to provide small, robust tooling for HTTP servers. Making
it a great solution for single page applications, web sites, hybrids, or public
HTTP APIs.
Built on Connect you can use _only_ what you need, and nothing more, applications
can be as big or as small as you like, even a single file. Express does
not force you to use any specific ORM or template engine. With support for over
14 template engines via [Consolidate.js](http://github.com/visionmedia/consolidate.js)
you can quickly craft your perfect framework.
* Session support
* Cache API
* Mime helpers
* ETag support
* Persistent flash notifications
* Cookie support
* JSON-RPC
* Logging
* and _much_ more!

# app
Application prototype.
# app.use()
Proxy `connect#use()` to apply settings to
mounted applications.
# app.engine()
Register the given template engine callback `fn`
as `ext`.
By default will `require()` the engine based on the
file extension. For example if you try to render
a "foo.jade" file Express will invoke the following internally:
app.engine('jade', require('jade').__express);
For engines that do not provide `.__express` out of the box,
or if you wish to "map" a different extension to the template engine
you may use this method. For example mapping the EJS template engine to
".html" files
app.engine('html', require('ejs').renderFile);
In this case EJS provides a `.renderFile()` method with
the same signature that Express expects: `(path, options, callback)`,
though note that it aliases this method as `ejs.__express` internally
so if you're using ".ejs" extensions you dont need to do anything.
Some template engines do not follow this convention, the
[Consolidate.js](https://github.com/visionmedia/consolidate.js)
library was created to map all of node's popular template
engines to follow this convention, thus allowing them to
work seemlessly within Express.
# app.param()
Map the given param placeholder `name`(s) to the given callback(s).
Parameter mapping is used to provide pre-conditions to routes
which use normalized placeholders. For example a _:user_id_ parameter
could automatically load a user's information from the database without
any additional code,
The callback uses the samesignature as middleware, the only differencing
being that the value of the placeholder is passed, in this case the _id_
of the user. Once the `next()` function is invoked, just like middleware
it will continue on to execute the route, or subsequent parameter functions.
app.param('user_id', function(req, res, next, id){
User.find(id, function(err, user){
if (err) {
next(err);
} else if (user) {
req.user = user;
next();
} else {
next(new Error('failed to load user'));
}
});
});
# app.set()
Assign `setting` to `val`, or return `setting`'s value.
app.set('foo', 'bar');
app.get('foo');
// => "bar"
Mounted servers inherit their parent server's settings.
# app.enabled()
Check if `setting` is enabled (truthy).
app.enabled('foo')
// => false
app.enable('foo')
app.enabled('foo')
// => true
# app.disabled()
Check if `setting` is disabled.
app.disabled('foo')
// => true
app.enable('foo')
app.disabled('foo')
// => false
# app.enable()
Enable `setting`.
# app.disable()
Disable `setting`.
# app.configure()
Configure callback for zero or more envs,
when no `env` is specified that callback will
be invoked for all environments. Any combination
can be used multiple times, in any order desired.
## Examples
app.configure(function(){
// executed for all envs
});
app.configure('stage', function(){
// executed staging env
});
app.configure('stage', 'production', function(){
// executed for stage and production
});
## Note
These callbacks are invoked immediately, and
are effectively sugar for the following.
var env = process.env.NODE_ENV || 'development';
switch (env) {
case 'development':
...
break;
case 'stage':
...
break;
case 'production':
...
break;
}
# app.all()
Special-cased "all" method, applying the given route `path`,
middleware, and callback to _every_ HTTP method.
# app.render()
Render the given view `name` name with `options`
and a callback accepting an error and the
rendered template string.
## Example
app.render('email', { name: 'Tobi' }, function(err, html){
// ...
})
# app.listen()
Listen for connections.
A node `http.Server` is returned, with this
application (which is a `Function`) as its
callback. If you wish to create both an HTTP
and HTTPS server you may do so with the "http"
and "https" modules as shown here.
var http = require('http')
, https = require('https')
, express = require('express')
, app = express();
http.createServer(app).listen(80);
http.createServer({ ... }, app).listen(443);

# app
Application prototype.
# app.use()
Proxy `connect#use()` to apply settings to
mounted applications.
# app.engine()
Register the given template engine callback `fn`
as `ext`.
By default will `require()` the engine based on the
file extension. For example if you try to render
a "foo.jade" file Express will invoke the following internally:
app.engine('jade', require('jade').__express);
For engines that do not provide `.__express` out of the box,
or if you wish to "map" a different extension to the template engine
you may use this method. For example mapping the EJS template engine to
".html" files
app.engine('html', require('ejs').renderFile);
In this case EJS provides a `.renderFile()` method with
the same signature that Express expects: `(path, options, callback)`,
though note that it aliases this method as `ejs.__express` internally
so if you're using ".ejs" extensions you dont need to do anything.
Some template engines do not follow this convention, the
[Consolidate.js](https://github.com/visionmedia/consolidate.js)
library was created to map all of node's popular template
engines to follow this convention, thus allowing them to
work seemlessly within Express.
# app.param()
Map the given param placeholder `name`(s) to the given callback(s).
Parameter mapping is used to provide pre-conditions to routes
which use normalized placeholders. For example a _:user_id_ parameter
could automatically load a user's information from the database without
any additional code,
The callback uses the samesignature as middleware, the only differencing
being that the value of the placeholder is passed, in this case the _id_
of the user. Once the `next()` function is invoked, just like middleware
it will continue on to execute the route, or subsequent parameter functions.
app.param('user_id', function(req, res, next, id){
User.find(id, function(err, user){
if (err) {
next(err);
} else if (user) {
req.user = user;
next();
} else {
next(new Error('failed to load user'));
}
});
});
# app.set()
Assign `setting` to `val`, or return `setting`'s value.
app.set('foo', 'bar');
app.get('foo');
// => "bar"
Mounted servers inherit their parent server's settings.
# app.enabled()
Check if `setting` is enabled (truthy).
app.enabled('foo')
// => false
app.enable('foo')
app.enabled('foo')
// => true
# app.disabled()
Check if `setting` is disabled.
app.disabled('foo')
// => true
app.enable('foo')
app.disabled('foo')
// => false
# app.enable()
Enable `setting`.
# app.disable()
Disable `setting`.
# app.configure()
Configure callback for zero or more envs,
when no `env` is specified that callback will
be invoked for all environments. Any combination
can be used multiple times, in any order desired.
## Examples
app.configure(function(){
// executed for all envs
});
app.configure('stage', function(){
// executed staging env
});
app.configure('stage', 'production', function(){
// executed for stage and production
});
## Note
These callbacks are invoked immediately, and
are effectively sugar for the following.
var env = process.env.NODE_ENV || 'development';
switch (env) {
case 'development':
...
break;
case 'stage':
...
break;
case 'production':
...
break;
}
# app.all()
Special-cased "all" method, applying the given route `path`,
middleware, and callback to _every_ HTTP method.
# app.render()
Render the given view `name` name with `options`
and a callback accepting an error and the
rendered template string.
## Example
app.render('email', { name: 'Tobi' }, function(err, html){
// ...
})
# app.listen()
Listen for connections.
A node `http.Server` is returned, with this
application (which is a `Function`) as its
callback. If you wish to create both an HTTP
and HTTPS server you may do so with the "http"
and "https" modules as shown here.
var http = require('http')
, https = require('https')
, express = require('express')
, app = express();
http.createServer(app).listen(80);
http.createServer({ ... }, app).listen(443);
# req
Request prototype.
# req.get
Return request header.
The `Referrer` header field is special-cased,
both `Referrer` and `Referer` are interchangeable.
## Examples
req.get('Content-Type');
// => "text/plain"
req.get('content-type');
// => "text/plain"
req.get('Something');
// => undefined
Aliased as `req.header()`.
# req.accepts()
Check if the given `type(s)` is acceptable, returning
the best match when true, otherwise `undefined`, in which
case you should respond with 406 "Not Acceptable".
The `type` value may be a single mime type string
such as "application/json", the extension name
such as "json", a comma-delimted list such as "json, html, text/plain",
or an array `["json", "html", "text/plain"]`. When a list
or array is given the _best_ match, if any is returned.
## Examples
// Accept: text/html
req.accepts('html');
// => "html"
// Accept: text/*, application/json
req.accepts('html');
// => "html"
req.accepts('text/html');
// => "text/html"
req.accepts('json, text');
// => "json"
req.accepts('application/json');
// => "application/json"
// Accept: text/*, application/json
req.accepts('image/png');
req.accepts('png');
// => undefined
// Accept: text/*;q=.5, application/json
req.accepts(['html', 'json']);
req.accepts('html, json');
// => "json"
# req.acceptsCharset()
Check if the given `charset` is acceptable,
otherwise you should respond with 406 "Not Acceptable".
# req.acceptsLanguage()
Check if the given `lang` is acceptable,
otherwise you should respond with 406 "Not Acceptable".
# req.param()
Return the value of param `name` when present or `defaultValue`.
- Checks body params, ex: id=12, {"id":12}
- Checks route placeholders, ex: _/user/:id_
- Checks query string params, ex: ?id=12
To utilize request bodies, `req.body`
should be an object. This can be done by using
the `connect.bodyParser()` middleware.
# req.is()
Check if the incoming request contains the "Content-Type"
header field, and it contains the give mime `type`.
## Examples
// With Content-Type: text/html; charset=utf-8
req.is('html');
req.is('text/html');
req.is('text/*');
// => true
// When Content-Type is application/json
req.is('json');
req.is('application/json');
req.is('application/*');
// => true
req.is('html');
// => false
Now within our route callbacks, we can use to to assert content types
such as "image/jpeg", "image/png", etc.
app.post('/image/upload', function(req, res, next){
if (req.is('image/*')) {
// do something
} else {
next();
}
});
# res
Response prototype.
# res.status()
Set status `code`.
# res.send()
Send a response.
## Examples
res.send(new Buffer('wahoo'));
res.send({ some: 'json' });
res.send('<p>some html</p>');
res.send(404, 'Sorry, cant find that');
res.send(404);
# res.json()
Send JSON response.
## Examples
res.json(null);
res.json({ user: 'tj' });
res.json(500, 'oh noes!');
res.json(404, 'I dont have that');
# res.sendfile()
Transfer the file at the given `path`.
Automatically sets the _Content-Type_ response header field.
The callback `fn(err)` is invoked when the transfer is complete
or when an error occurs. Be sure to check `res.sentHeader`
if you wish to attempt responding, as the header and some data
may have already been transferred.
## Options
- `maxAge` defaulting to 0
- `root` root directory for relative filenames
## Examples
The following example illustrates how `res.sendfile()` may
be used as an alternative for the `static()` middleware for
dynamic situations. The code backing `res.sendfile()` is actually
the same code, so HTTP cache support etc is identical.
app.get('/user/:uid/photos/:file', function(req, res){
var uid = req.params.uid
, file = req.params.file;
req.user.mayViewFilesFrom(uid, function(yes){
if (yes) {
res.sendfile('/uploads/' + uid + '/' + file);
} else {
res.send(403, 'Sorry! you cant see that.');
}
});
});
# res.download()
Transfer the file at the given `path` as an attachment.
Optionally providing an alternate attachment `filename`,
and optional callback `fn(err)`. The callback is invoked
when the data transfer is complete, or when an error has
ocurred. Be sure to check `res.headerSent` if you plan to respond.
# res.format()
Respond to the Acceptable formats using an `obj`
of mime-type callbacks.
This method uses `req.accepted`, an array of
acceptable types ordered by their quality values.
When "Accept" is not present the _first_ callback
is invoked, otherwise the first match is used. When
no match is performed the server responds with
406 "Not Acceptable".
Content-Type is set for you, however if you choose
you may alter this within the callback using `res.type()`
or `res.set('Content-Type', ...)`.
res.format({
'text/plain': function(){
res.send('hey');
},
'text/html': function(){
res.send('<p>hey</p>');
},
'appliation/json': function(){
res.send({ message: 'hey' });
}
});
In addition to canonicalized MIME types you may
## also use extnames mapped to these types
res.format({
text: function(){
res.send('hey');
},
html: function(){
res.send('<p>hey</p>');
},
json: function(){
res.send({ message: 'hey' });
}
});
# res.attachment()
Set _Content-Disposition_ header to _attachment_ with optional `filename`.
# res.set()
Set header `field` to `val`, or pass
an object of of header fields.
## Examples
res.set('Accept', 'application/json');
res.set({ Accept: 'text/plain', 'X-API-Key': 'tobi' });
# res.get()
Get value for header `field`.
# res.clearCookie()
Clear cookie `name`.
# res.signedCookie()
Set a signed cookie with the given `name` and `val`.
See `res.cookie()` for details.
# res.cookie()
Set cookie `name` to `val`, with the given `options`.
## Options
- `maxAge` max-age in milliseconds, converted to `expires`
- `path` defaults to "/"
## Examples
// "Remember Me" for 15 minutes
res.cookie('rememberme', '1', { expires: new Date(Date.now() + 900000), httpOnly: true });
// save as above
res.cookie('rememberme', '1', { maxAge: 900000, httpOnly: true })
# res.redirect()
Redirect to the given `url` with optional response `status`
defaulting to 302.
The given `url` can also be the name of a mapped url, for
example by default express supports "back" which redirects
to the _Referrer_ or _Referer_ headers or "/".
## Examples
res.redirect('/foo/bar');
res.redirect('http://example.com');
res.redirect(301, 'http://example.com');
res.redirect('../login'); // /blog/post/1 -> /blog/login
## Mounting
When an application is mounted, and `res.redirect()`
is given a path that does _not_ lead with "/". For
example suppose a "blog" app is mounted at "/blog",
the following redirect would result in "/blog/login":
res.redirect('login');
While the leading slash would result in a redirect to "/login":
res.redirect('/login');
# res.render()
Render `view` with the given `options` and optional callback `fn`.
When a callback function is given a response will _not_ be made
automatically, otherwise a response of _200_ and _text/html_ is given.
## Options
- `status` Response status code (`res.statusCode`)
- `charset` Set the charset (`res.charset`)
## Reserved locals
- `cache` boolean hinting to the engine it should cache
- `filename` filename of the view being rendered

<h3>Express 1.x to 2.x Migration</h3>
<h3>HTTPS</h3>
<p> Creating an HTTPS server is simply, simply pass the TLS options to <em>express.createServer()</em>:</p>
<pre><code> var app = express.createServer({
key: ...
, cert: ...
});
app.listen(443);
</code></pre>
<h3>req.header() Referrer</h3>
<p> Previously if anyone was doing something similar to:</p>
<pre><code> req.headers.referrer || req.headers.referer
req.header('Referrer') || req.header('Referer')
</code></pre>
<p> With the new special-case we may now simply use <em>Referrer</em> which will return either if defined:</p>
<pre><code> req.header('Referrer')
</code></pre>
<h3>res.local(name, val)</h3>
<p> Previously all local variables had to be passed to <em>res.render()</em>, or either <em>app.helpers()</em> or <em>app.dynamicHelpers()</em>, now we may do this at the request-level progressively. The <em>res.local()</em> method accepts a <em>name</em> and <em>val</em>, however the locals passed to <em>res.render()</em> will take precedence.</p>
<p> For example we may utilize this feature to create locals in middleware:</p>
<pre><code> function loadUser(req, res, next) {
User.get(req.params.id, function(err, user){
res.local('user', user);
next();
});
}
app.get('/user/:id', loadUser, function(req, res){
res.render('user');
});
</code></pre>
<h3>req.param(name[, defaultValue])</h3>
<p> Previously only <em>name</em> was accepted, so some of you may have been doing the following:</p>
<pre><code> var id = req.param('id') || req.user.id;
</code></pre>
<p> The new <em>defaultValue</em> argument can handle this nicely:</p>
<pre><code> var id = req.param('id', req.user.id);
</code></pre>
<h3>app.helpers() / app.locals()</h3>
<p> <em>app.locals()</em> is now an alias of <em>app.helpers()</em>, as helpers makes more sense for functions.</p>
<h3>req.accepts(type)</h3>
<p> <em>req.accepts()</em> now accepts extensions:</p>
<pre><code> // Accept: text/html
req.accepts('html');
req.accepts('.html');
// =&gt; true
// Accept: text/*; application/json
req.accepts('html');
req.accepts('text/*');
req.accepts('text/plain');
req.accepts('application/json');
// =&gt; true
req.accepts('image/png');
req.accepts('png');
// =&gt; false
</code></pre>
<h3>res.cookie()</h3>
<p> Previously only directly values could be passed, so for example:</p>
<pre><code>res.cookie('rememberme', 'yes', { expires: new Date(Date.now() + 900000) });
</code></pre>
<p>However now we have the alternative <em>maxAge</em> property which may be used to set <em>expires</em> relative to <em>Date.now()</em> in milliseconds, so our example above can now become:</p>
<pre><code>res.cookie('rememberme', 'yes', { maxAge: 900000 });
</code></pre>
<h3>res.download() / res.sendfile()</h3>
<p> Both of these methods now utilize Connect&rsquo;s static file server behind the scenes (actually the previous Express code was ported to Connect 1.0). With this change comes a change to the callback as well. Previously the <em>path</em> and <em>stream</em> were passed, however now only an <em>error</em> is passed, when no error has occurred the callback will be invoked indicating that the file transfer is complete. The callback remains optional:</p>
<pre><code> res.download('/path/to/file');
res.download('/path/to/file', function(err){
if (err) {
console.error(err);
} else {
console.log('transferred');
}
});
</code></pre>
<p> The <em>stream threshold</em> setting was removed.</p>
<h3>res.render()</h3>
<p> Previously locals were passed as a separate key:</p>
<pre><code> res.render('user', { layout: false, locals: { user: user }});
</code></pre>
<p> In Express 2.0 both the locals and the options are one in the same, meaning you cannot have a local variable named <em>layout</em> as it is reserved for express, however this cleans up the API:</p>
<pre><code> res.render('user', { layout: false, user: user });
</code></pre>
<h3>res.partial()</h3>
<p> Express 2.0 adds the <em>res.partial()</em> method, helpful for rendering partial fragments over WebSockets or Ajax requests etc. The API is identical to the <em>partial()</em> calls within views.</p>
<pre><code> // render a collection of comments
res.partial('comment', [comment1, comment2]);
// render a single comment
res.partial('comment', comment);
</code></pre>
<h3>partial() locals</h3>
<p> Both <em>res.partial()</em> and the <em>partial()</em> functions accept a single object consisting of both the options and the locals. Previously with Express 1.x you may pass <em>user</em> to a partial, along with <em>date</em> like so:</p>
<pre><code> partial('user', { object: user, locals: { date: new Date }})
</code></pre>
<p>or perhaps if you preferred not to use the inferred name <em>user</em> you may used a local for this as well:</p>
<pre><code> partial('user', { locals: { user: user, date: new Date }})
</code></pre>
<p> With recent changes to Express 2.x the object passed is now both, so the following is valid for the <em>object</em> option and locals:</p>
<pre><code> partial('user', { object: user, date: new Date })
</code></pre>
<p> Or the following which is equivalent, however the local var name is explicitly set to <em>user</em> instead of deduced from the filename.</p>
<pre><code> partial('user', { user: user, date: new Date })
</code></pre>
<p> When a &ldquo;basic&rdquo; object aka <em>{}</em> or <em>new Object</em> is passed, it is considered options, otherwise it is considered the <em>object</em>. The following are equivalent:</p>
<pre><code> partial('user', user);
partial('user', { object: user });
</code></pre>
<h3>Template Engine Compliance</h3>
<p> To comply with Express previously engines needed the following signature:</p>
<pre><code> engine.render(str, options, function(err){});
</code></pre>
<p> Now they must export a <em>compile()</em> function, returning a function which when called with local variables will render the template. This allows Express to cache the compiled function in memory during production.</p>
<pre><code> var fn = engine.compile(str, options);
fn(locals);
</code></pre>
<h3>View Partial Lookup</h3>
<p> Previously partials were loaded relative to the now removed <em>view partials</em> directory setting, or by default <em>views/partials</em>, now they are relative to the view calling them, read more on <a href="guide.html#view-lookup">view lookup</a>.</p>
<h3>Mime Types</h3>
<p> Express and Connect now utilize the <em>mime</em> module in npm, so to add more use:</p>
<pre><code> require('mime').define({ 'foo/bar': ['foo', 'bar'] });
</code></pre>
<h3>static() middleware</h3>
<p> Previously named <code>staticProvider()</code>, the now <code>static()</code> middleware takes a single directory path, followed by options.</p>
<pre><code> app.use(express.static(__dirname + '/public', { maxAge: oneYear }));
</code></pre>
<p>Previously when using options the <code>root</code> option would be used for this:</p>
<pre><code> app.use(express.staticProvider({ root: __dirname + '/public', maxAge: oneYear }));
</code></pre>

# req
Request prototype.
# req.get
Return request header.
The `Referrer` header field is special-cased,
both `Referrer` and `Referer` are interchangeable.
## Examples
req.get('Content-Type');
// => "text/plain"
req.get('content-type');
// => "text/plain"
req.get('Something');
// => undefined
Aliased as `req.header()`.
# req.accepts()
Check if the given `type(s)` is acceptable, returning
the best match when true, otherwise `undefined`, in which
case you should respond with 406 "Not Acceptable".
The `type` value may be a single mime type string
such as "application/json", the extension name
such as "json", a comma-delimted list such as "json, html, text/plain",
or an array `["json", "html", "text/plain"]`. When a list
or array is given the _best_ match, if any is returned.
## Examples
// Accept: text/html
req.accepts('html');
// => "html"
// Accept: text/*, application/json
req.accepts('html');
// => "html"
req.accepts('text/html');
// => "text/html"
req.accepts('json, text');
// => "json"
req.accepts('application/json');
// => "application/json"
// Accept: text/*, application/json
req.accepts('image/png');
req.accepts('png');
// => undefined
// Accept: text/*;q=.5, application/json
req.accepts(['html', 'json']);
req.accepts('html, json');
// => "json"
# req.acceptsCharset()
Check if the given `charset` is acceptable,
otherwise you should respond with 406 "Not Acceptable".
# req.acceptsLanguage()
Check if the given `lang` is acceptable,
otherwise you should respond with 406 "Not Acceptable".
# req.param()
Return the value of param `name` when present or `defaultValue`.
- Checks body params, ex: id=12, {"id":12}
- Checks route placeholders, ex: _/user/:id_
- Checks query string params, ex: ?id=12
To utilize request bodies, `req.body`
should be an object. This can be done by using
the `connect.bodyParser()` middleware.
# req.is()
Check if the incoming request contains the "Content-Type"
header field, and it contains the give mime `type`.
## Examples
// With Content-Type: text/html; charset=utf-8
req.is('html');
req.is('text/html');
req.is('text/*');
// => true
// When Content-Type is application/json
req.is('json');
req.is('application/json');
req.is('application/*');
// => true
req.is('html');
// => false
Now within our route callbacks, we can use to to assert content types
such as "image/jpeg", "image/png", etc.
app.post('/image/upload', function(req, res, next){
if (req.is('image/*')) {
// do something
} else {
next();
}

# res
Response prototype.
# res.status()
Set status `code`.
# res.send()
Send a response.
## Examples
res.send(new Buffer('wahoo'));
res.send({ some: 'json' });
res.send('<p>some html</p>');
res.send(404, 'Sorry, cant find that');
res.send(404);
# res.json()
Send JSON response.
## Examples
res.json(null);
res.json({ user: 'tj' });
res.json(500, 'oh noes!');
res.json(404, 'I dont have that');
# res.sendfile()
Transfer the file at the given `path`.
Automatically sets the _Content-Type_ response header field.
The callback `fn(err)` is invoked when the transfer is complete
or when an error occurs. Be sure to check `res.sentHeader`
if you wish to attempt responding, as the header and some data
may have already been transferred.
## Options
- `maxAge` defaulting to 0
- `root` root directory for relative filenames
## Examples
The following example illustrates how `res.sendfile()` may
be used as an alternative for the `static()` middleware for
dynamic situations. The code backing `res.sendfile()` is actually
the same code, so HTTP cache support etc is identical.
app.get('/user/:uid/photos/:file', function(req, res){
var uid = req.params.uid
, file = req.params.file;
req.user.mayViewFilesFrom(uid, function(yes){
if (yes) {
res.sendfile('/uploads/' + uid + '/' + file);
} else {
res.send(403, 'Sorry! you cant see that.');
}
});
});
# res.download()
Transfer the file at the given `path` as an attachment.
Optionally providing an alternate attachment `filename`,
and optional callback `fn(err)`. The callback is invoked
when the data transfer is complete, or when an error has
ocurred. Be sure to check `res.headerSent` if you plan to respond.
# res.format()
Respond to the Acceptable formats using an `obj`
of mime-type callbacks.
This method uses `req.accepted`, an array of
acceptable types ordered by their quality values.
When "Accept" is not present the _first_ callback
is invoked, otherwise the first match is used. When
no match is performed the server responds with
406 "Not Acceptable".
Content-Type is set for you, however if you choose
you may alter this within the callback using `res.type()`
or `res.set('Content-Type', ...)`.
res.format({
'text/plain': function(){
res.send('hey');
},
'text/html': function(){
res.send('<p>hey</p>');
},
'appliation/json': function(){
res.send({ message: 'hey' });
}
});
In addition to canonicalized MIME types you may
## also use extnames mapped to these types
res.format({
text: function(){
res.send('hey');
},
html: function(){
res.send('<p>hey</p>');
},
json: function(){
res.send({ message: 'hey' });
}
});
# res.attachment()
Set _Content-Disposition_ header to _attachment_ with optional `filename`.
# res.set()
Set header `field` to `val`, or pass
an object of of header fields.
## Examples
res.set('Accept', 'application/json');
res.set({ Accept: 'text/plain', 'X-API-Key': 'tobi' });
# res.get()
Get value for header `field`.
# res.clearCookie()
Clear cookie `name`.
# res.signedCookie()
Set a signed cookie with the given `name` and `val`.
See `res.cookie()` for details.
# res.cookie()
Set cookie `name` to `val`, with the given `options`.
## Options
- `maxAge` max-age in milliseconds, converted to `expires`
- `path` defaults to "/"
## Examples
// "Remember Me" for 15 minutes
res.cookie('rememberme', '1', { expires: new Date(Date.now() + 900000), httpOnly: true });
// save as above
res.cookie('rememberme', '1', { maxAge: 900000, httpOnly: true })
# res.redirect()
Redirect to the given `url` with optional response `status`
defaulting to 302.
The given `url` can also be the name of a mapped url, for
example by default express supports "back" which redirects
to the _Referrer_ or _Referer_ headers or "/".
## Examples
res.redirect('/foo/bar');
res.redirect('http://example.com');
res.redirect(301, 'http://example.com');
res.redirect('../login'); // /blog/post/1 -> /blog/login
## Mounting
When an application is mounted, and `res.redirect()`
is given a path that does _not_ lead with "/". For
example suppose a "blog" app is mounted at "/blog",
the following redirect would result in "/blog/login":
res.redirect('login');
While the leading slash would result in a redirect to "/login":
res.redirect('/login');
