SET mykey "Hello, Redis!"

GET mykey

DEL mykey

SET username "JohnDoe"
GET username

RPUSH mylist "item1"
RPUSH mylist "item2"
LRANGE mylist 0 -1

HSET user:id:1001 username "john_doe"
HSET user:id:1001 age 25
HGETALL user:id:1001

SADD myset "apple"
SADD myset "banana"
SMEMBERS myset

ZADD leaderboard 100 "PlayerA"
ZADD leaderboard 200 "PlayerB"
ZRANGE leaderboard 0 -1

KEYS *

EXISTS mykey

MULTI

EXEC

DISCARD

EXPIRE mykey 60

TTL mykey

const Redis = require('ioredis');
const redis = new Redis();

// 设置键值对
redis.set('mykey', 'Hello, Redis!');

// 获取键值对的值
redis.get('mykey').then((result) => {
  console.log('Value of mykey:', result);
});

// 删除键值对
redis.del('mykey');

// 列表类型操作
redis.rpush('mylist', 'item1', 'item2');
redis.lrange('mylist', 0, -1).then((result) => {
  console.log('Values in mylist:', result);
});

// 其他类型操作...

// 查询键
redis.keys('*').then((result) => {
  console.log('All keys:', result);
});

// 事务处理
redis.multi()
  .set('transaction:key1', 'value1')
  .set('transaction:key2', 'value2')
  .exec()
  .then((results) => {
    console.log('Transaction results:', results);
  });

// 设置过期时间
redis.expire('mykey', 60);

// 获取剩余过期时间
redis.ttl('mykey').then((result) => {
  console.log('Time to live for mykey:', result);
});
