Redis client for Golang [![Build Status](https://travis-ci.org/go-redis/redis.png?branch=master)](https://travis-ci.org/go-redis/redis)
=======================
Supports:
- Redis 3 commands except QUIT, MONITOR, SLOWLOG and SYNC.
- Pub/Sub.
- Transactions.
- Pipelines.
- Connection pool. Client can be safely used from multiple goroutines.
- Timeouts.
- [Redis Sentinel](http://godoc.org/gopkg.in/redis.v3#NewFailoverClient).
- [Redis Cluster](http://godoc.org/gopkg.in/redis.v3#NewClusterClient).
API docs: http://godoc.org/gopkg.in/redis.v3.
Examples: http://godoc.org/gopkg.in/redis.v3#pkg-examples.
Installation
------------
Install:
go get gopkg.in/redis.v3
Quickstart
----------
```go
func ExampleNewClient() {
client := redis.NewClient(&redis.Options{
Addr: "localhost:6379",
Password: "", // no password set
DB: 0, // use default DB
})
pong, err := client.Ping().Result()
fmt.Println(pong, err)
// Output: PONG <nil>
}
func ExampleClient() {
err := client.Set("key", "value", 0).Err()
if err != nil {
panic(err)
}
val, err := client.Get("key").Result()
if err != nil {
panic(err)
}
fmt.Println("key", val)
val2, err := client.Get("key2").Result()
if err == redis.Nil {
fmt.Println("key2 does not exists")
} else if err != nil {
panic(err)
} else {
fmt.Println("key2", val2)
}
// Output: key value
// key2 does not exists
}
```
Howto
-----
Please go through [examples](http://godoc.org/gopkg.in/redis.v3#pkg-examples) to get an idea how to use this package.
Look and feel

Some corner cases:
SET key value EX 10 NX
set, err := client.SetNX("key", "value", 10*time.Second).Result()
SORT list LIMIT 0 2 ASC
vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeByScore{
Min: "-inf",
Max: "+inf",
Offset: 0,
Count: 2,
}).Result()
ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()
EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, []string{"hello"}).Result()
