How to end an express.js / node POST response?

Question

Im trying to just stop the post request after I\'ve saved a document to the DB, ie:

app.post(\'/blah\'), function(req,res){ 
//my code does a bunch of stuff

While you can use the underlying end method borrowed from Node's http module, Express.js has its own send method that calls end when appropriate:

/**
 * Send a response.
 *
 * Examples:
 *
 *     res.send(new Buffer('wahoo'));
 *     res.send({ some: 'json' });
 *     res.send('
some html
');
 *     res.send(404, 'Sorry, cant find that');
 *     res.send(404);
 *
 * @param {Mixed} body or status
 * @param {Mixed} body
 * @return {ServerResponse}
 * @api public
 */
res.send = function(body){
  .
  .
  .

  // respond
  this.end(head ? null : body);
  return this;
};
