Quickstart

import (
"context"
"github.com/go-redis/redis/v8"
)
var ctx = context.Background()
func ExampleClient() {
rdb := redis.NewClient(&redis.Options{
Addr:
"localhost:6379",
Password: "", // no password set
DB:
0,
// use default DB
})
err := rdb.Set(ctx, "key", "value", 0).Err()
if err != nil {
panic(err)
}
val, err := rdb.Get(ctx, "key").Result()
if err != nil {
panic(err)
}
fmt.Println("key", val)
val2, err := rdb.Get(ctx, "key2").Result()
if err == redis.Nil {
fmt.Println("key2 does not exist")
} else if err != nil {
panic(err)
} else {
fmt.Println("key2", val2)
}
// Output: key value
// key2 does not exist
}

Look and feel
Some corner cases:

// SET key value EX 10 NX
set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
// SET key value keepttl NX
set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
// SORT list LIMIT 0 2 ASC
vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
Min: "-inf",
Max: "+inf",
Offset: 0,
Count: 2,
}).Result()
// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
vals, err := rdb.ZInterStore(ctx, "out", &redis.ZStore{
Keys: []string{"zset1", "zset2"},
Weights: []int64{2, 3}
}).Result()
// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
vals, err := rdb.Eval(ctx, "return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
// custom command
res, err := rdb.Do(ctx, "set", "key", "value").Result()
