Class Response

Example:

res.append('Set-Cookie', 'foo=bar; Path=/; HttpOnly'); res.append('Warning', '199 Miscellaneous warning');

Examples:

// "Remember Me" for 15 minutes res.cookie({ name: "rememberme", value: "1", expires: new Date(Date.now() + 900000), httpOnly: true });

Optionally providing an alternate attachment filename.

This function will set the Content-Disposition header, overriding any existing Content-Disposition header in order to set the attachment and filename.

This method uses res.sendFile().

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>');
 },

 'application/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' });
 }

});

By default Express passes an Error with a .status of 406 to next(err) if a match is not made. If you provide a .default callback it will be invoked instead.

Examples:

res.json(null);
res.json({ user: 'deno' });

Examples:

res.jsonp(null);
res.jsonp({ user: 'deno' });

Examples:

res.links({ next: 'http://api.example.com/users?page=2', last: 'http://api.example.com/users?page=5' });

The given url can also be "back", which redirects to the Referrer or Referer headers or "/".

Examples:

res.location('/foo/bar').; res.location('http://example.com'); res.location('../login');

The resulting url is determined by res.location().

Examples:

res.redirect('/foo/bar'); res.redirect('http://example.com'); res.redirect(301, 'http://example.com'); res.redirect('../login'); // /blog/post/1 -> /blog/login

Options:

• cache boolean hinting to the engine it should cache
• filename filename of the view being rendered

Examples:

res.send({ some: 'json' });
res.send('<p>some html</p>');

Automatically sets the Content-Type response header field.

Sets the response status to code and the body of the response to the standard description from deno's http_status.STATUS_TEXT or the code number if no description.

Examples:

res.sendStatus(200);

Examples:

res.set('Accept', 'application/json');
res.set({
  'Accept-Language': "en-US, en;q=0.5",
  'Accept': 'text/html',
});

This method deviates from Express due to the naming clash with Deno.Response status property.

Examples:

res.type('.html');
res.type('html');
res.type('json');
res.type('application/json');
res.type('png');
