It looks as if you want to use Express and the express.compress middleware. That will figure out if a browser supports gzip and/or deflate, so you don't have to.

A simple setup could look like this:

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

app.use(express.compress());
app.get('/', function(req, res) {
  res.send({ app_id: 'A3000990' });
});
app.listen(3000);

If your data is a JSON-string, you have to set the correct content-type header yourself:

res.setHeader('Content-Type', 'application/json');
res.send(data);
