Node.js Express req.query is undefined

Question

Node.js Express req.query is undefined

I'm running the following code on Node.js with Express 4.7.2

express.get('/test1',function(req, res) {
  var ttt = false;
  if (req.query.username === undefined) ttt = true;
  res.json({query: ttt});
});

I call the URL:

{{protocol}}://{{server}}/test1?username=1

And I get the result:

{query: true}

Which shows req.query.username is indeed undefined

What am I missing? How come the query param is not passed in?

The code you've shown works fine for me with node v0.10.30 and express 4.8.7:

var app = require('express')();

app.get('/test1',function(req, res) {
  var ttt = false;
  if (req.query.username === undefined) ttt = true;
  res.json({query: ttt});
});

app.listen(8000);

I then navigate to http://localhost:8000/test1?username=1 and it displays {"query":false}.
