http://expressjs.com/
var app = express.createServer(); app.get('/', function(req, res){ res.send('Hello World'); }); app.listen(3000);`
I can not find the corresponding res.send link inside the Node.js manual:
res.send
http://nodejs.org/docs/v0.4.12/api/http.html#http.ServerResponse
Is this an undocumented property or is id an integral part of HTTP? If so, where can I find the appropriate link for all properties?
This is part of Express.js , not Node.js.
Remember that node.js does not provide advanced features like express.js (and it never will, node.js will remain small)
You can take a look at the node toolbox to find awesome node libraries
