Messy memcached partial reimplementation I wrote on my very first day with node. Last time I checked, it's faster in some cases.

mem.js

var net = require('net');

var store = { }

var server = net.createServer(function (socket) {
  var buffer = "";
  var index = 0;
  
  socket.on("data", function(data) {
    buffer += data.toString('utf8');
    
    index = buffer.indexOf("\n");
    if (index != -1) {
      command = buffer.substr(0, index);
      buffer = buffer.substr(index + 1);
    }
    console.log(buffer)
    x = command.split(' ');
    x[x.length - 1] = x[x.length - 1].trim()
    
    if (x[0] == 'get') 
      socket.write(store[x[1].trim()]);
    else if (x[0] == 'set') 
      store[x[1]] = x[2].trim();
    else if (x[0] == 'show')
      console.log(store);
  });
});

server.listen(1337, "127.0.0.1");
