Client examples

Telnet

Connect to an NCached server via telnet:

telnet <server_ip> <server_port>

You can store and retrieve data just as with a normal memcached server:

set foo 0 20 3
bar

And then:

get foo

Will return:

VALUE foo 0 3
bar
END

Memcached client for node

Using memcached library:

const Memcached = require('memcached')
const memcached = new Memcached('localhost:11212')

memcached.set('foo', 'bar', 20, (err) => { 
  // you can use 'gets' command to retrieve the cas_token
  memcached.gets('foo', (err, data) => {
    // change value with 'cas' command
    memcached.cas('foo', 'redis', data.cas, 20, err => { /* stuff */ })
  })
})
