In Express or connect with Node.js, is there a way to call another route internally?

Question

So, I have the setup like this (in Express):

app.get(\'/mycall1\', function(req,res) { res.send(\'Good\'); });
app.get(\'/mycall2\', function(req,res) { res.

Like many things in javascript your original goal can be accomplished with sneakiness. We can overwrite the res.send function so that it doesn't call res.end; this will allow res.send to be called multiple times without issue. Note that this is an ugly, sneaky approach - not recommended, but potentially useful:

app.get('myAggregate', (req, res) => {
  // Overwrite `res.send` so it tolerates multiple calls:
  let restoreSend = res.send;
  res.send = () => { /* do nothing */ };

  // Call mycall1
  req.method = 'GET';
  req.url = '/mycall1';
  app.handle(req, res, () => {});

  // Call mycall2
  req.method = 'GET';
  req.url = '/mycall2';
  app.handle(req, res, () => {});

  // Restore `res.send` to its normal functionality
  res.send = restoreSend;

  // Finally, call `res.send` in conclusion of calling both mycall1 and mycall2
  res.send('Good AND Good2!');

});
