express-jsonstream

Simple middleware for JSON streaming in Express. Stringifys and sends object delimited by \n's with the Content-Type : application/jsonstream header

var jsonStream = require('express-jsonstream');
var express = require('express');
var app = express.createServer(jsonStream());

app.get('/stream-yo', function(req, res) {
  res.jsonStream({small:'world'});
  res.jsonStream({after:'all'});
  res.end();
});

app.listen(8553);
console.log('listening on', 8553);

You can run the example with:
