Connect

Body parser:

Status: the multipart body parser will be removed in Connect 3.

Parse request bodies, supports application/json,
application/x-www-form-urlencoded, and multipart/form-data.

This is equivalent to:

app.use(connect.json());
app.use(connect.urlencoded());
app.use(connect.multipart());

Examples:

 connect()
   .use(connect.bodyParser())
   .use(function(req, res) {
     res.end('viewing user ' + req.body.user.name);
   });

 $ curl -d 'user[name]=tj' http://local/
 $ curl -d '{"user":{"name":"tj"}}' -H "Content-Type: application/json" http://local/
