[10] Redis – Node.js

To jest przykład użycia Redis w Node.js

[1] Zainstaluj moduł klienta Redis.

[user01@vlsr01 ~]$ npm install redis

[2] Podstawowe użycie Node.js

[user01@vlsr01 ~]$ mcedit use_redis.js
var redis = require('redis');
var client = new redis.createClient();

client.auth('TajneHasło');

//ustaw i pobierz klucz
client.set('key01', 'value01');
client.get('key01', function (err, val) {
    console.log("key01.value :", val);
});

//dodaj i pobierz klucz
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);
});

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

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

//listuj
client.rpush('list01', 'value01');
client.rpush('list01', 'value02');
client.lrange('list01', 0, -1, function (err, val) {
    console.log("list01.value :", val);
});

//mieszaj
client.hset("hash01", "key01", "value01");
client.hset("hash01", "key02", "value02");
client.hgetall('hash01', function (err, val) {
    console.log("hash01.value :", val);
});

//ustaw
client.sadd("set01", "member01");
client.sadd("set01", "member02");
client.smembers('set01', function (err, val) {
    console.log("set01.value :", val);
});
