client.connect();

// set and get a Key
client.set('key01', 'value01');
client.get('key01', function (err, val) {
    console.log("key01.value :", val);
});

// append and get a Key
client.append('key01', ',value02');
client.get('key01', function (err, val) {
    console.log("key01.value :", val);
});

client.set('key02', 1);
client.get('key02', function (err, val) {
    console.log("key02.value :", val);
});

// increment
client.increment('key02', 100);
client.get('key02', function (err, val) {
    console.log("key02.value :", val);
});

// decrement
client.decrement('key02', 51);
client.get('key02', function (err, val) {
    console.log("key02.value :", val);
});

// delete a Key
client.delete('key03');
client.get('key03', function (err, val) {
    console.log("key03.value :", val);
});

client.close();

# run

node use_memcache.js

key01.value : value01
