var client = new memcache.Client();
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.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 ubuntu@dlp:~$ node use_memcache.js key01.value : value01 key01.value : value01,value02 key02.value : 1 key02.value : 101 key02.value : 50 key03.value : null |
