Ys

Node.js micro web framework.

Installation

npm install ys

Hello World:

var Ys = require('ys').Ys;

Ys("^/$").get = function(req,res){
    res.end("Hello World!");
};

Ys.run({debug:true});

In debug mode the server reloads itself on source changes. Do not use in production.

a.run({port:8780};);

b("^/$").get.html = function(req,res){
    res.end("<h1>Instance B</h1>");

b.run({port:8781});
