How to exit

.exit

http server

First create a js file

var http = require('http');

var s = http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.write('Hello \n');
  setTimeout(function() {
    res.end("world\n");
  }, 2000);
});

s.listen(8000);

Then using node program to run the js script. We can test the program by using a web browser or curl program.

# Terminal 1
node web-server.js

# Terminal 2
curl http://localhost:8000
OR use "-i" to include HTTP-header in the output
curl -i http://localhost:8000
