Installation

Install:

go get -u github.com/go-redis/redis

Import:

import "github.com/go-redis/redis"

Quickstart

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 exist")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2", val2)
	}
	// Output: key value
	// key2 does not exist
}

Howto

Please go through 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.ZRangeBy{
	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"}, "hello").Result()

Overview

Package redis implements a Redis client.

Example (CustomCommand)
package main

import (
	"fmt"

	"github.com/go-redis/redis"
)

var redisdb *redis.Client

func main() {
	Get := func(redisdb *redis.Client, key string) *redis.StringCmd {
		cmd := redis.NewStringCmd("get", key)
		redisdb.Process(cmd)
		return cmd
	}

	v, err := Get(redisdb, "key_does_not_exist").Result()
	fmt.Printf("%q %s", v, err)
}
Output:

"" redis: nil
Example (CustomCommand2)
package main

import (
	"fmt"

	"github.com/go-redis/redis"
)

var redisdb *redis.Client

func main() {
	v, err := redisdb.Do("get", "key_does_not_exist").String()
	fmt.Printf("%q %s", v, err)
}
Output:

"" redis: nil
Example (Instrumentation)
package main

import (
	"fmt"

	"github.com/go-redis/redis"
)

func main() {
	redisdb := redis.NewClient(&redis.Options{
		Addr: ":6379",
	})
	redisdb.WrapProcess(func(old func(cmd redis.Cmder) error) func(cmd redis.Cmder) error {
		return func(cmd redis.Cmder) error {
			fmt.Printf("starting processing: <%s>\n", cmd)
			err := old(cmd)
			fmt.Printf("finished processing: <%s>\n", cmd)
			return err
		}
	})

	redisdb.Ping()
}
Output:

starting processing: <ping: >
finished processing: <ping: PONG>

)

var redisdb *redis.Client

func main() {
	err := redisdb.Set("key", "value", 0).Err()
	if err != nil {
		panic(err)
	}

func (c *Client) Subscribe(channels ...string) *PubSub

Subscribe subscribes the client to the specified channels. Channels can be omitted to create empty subscription. Note that this method does not wait on a response from Redis, so the subscription may not be active immediately. To force the connection to wait, you may call the Receive() method on the returned *PubSub like so:

sub := client.Subscribe(queryResp)
iface, err := sub.Receive()
if err != nil {
    // handle error
}

// Should be *Subscription, but others are possible if other actions have been
// taken on sub since it was created.
switch iface.(type) {
case *Subscription:
    // subscribe succeeded
case *Message:
    // received first message
case *Pong:
    // pong received
default:
    // handle error
}

PubSub automatically reconnects to Redis Server and resubscribes to the channels in case of network errors.

Example
package main

import (
	"fmt"
	"time"

	"github.com/go-redis/redis"
)

var redisdb *redis.Client

func init() {
	redisdb = redis.NewClient(&redis.Options{
		Addr:         ":6379",
		DialTimeout:  10 * time.Second,
		ReadTimeout:  30 * time.Second,
		WriteTimeout: 30 * time.Second,
		PoolSize:     10,
		PoolTimeout:  30 * time.Second,
	})
}

func main() {
	pubsub := redisdb.Subscribe("mychannel1")

	// Wait for confirmation that subscription is created before publishing anything.
	_, err := pubsub.Receive()
	if err != nil {
		panic(err)
	}

	// Go channel which receives messages.
	ch := pubsub.Channel()

	// Publish a message.
	err = redisdb.Publish("mychannel1", "hello").Err()
	if err != nil {
		panic(err)
	}

	time.AfterFunc(time.Second, func() {
		// When pubsub is closed channel is closed too.
		_ = pubsub.Close()
	})

	// Consume messages.
	for msg := range ch {
		fmt.Println(msg.Channel, msg.Payload)
	}

}
Output:

mychannel1 hello

func (*PubSub) Channel

func (c *PubSub) Channel() <-chan *Message

Channel returns a Go channel for concurrently receiving messages. It periodically sends Ping messages to test connection health. The channel is closed with PubSub. Receive* APIs can not be used after channel is created.

func (*PubSub) Close

func (c *PubSub) Ping(payload ...string) error

func (*PubSub) Receive

func (c *PubSub) Receive() (interface{}, error)

Receive returns a message as a Subscription, Message, Pong or error. See PubSub example for details. This is low-level API and in most cases Channel should be used instead.

Example
package main

import (
	"fmt"
	"time"

	"github.com/go-redis/redis"
)

var redisdb *redis.Client

func main() {
	pubsub := redisdb.Subscribe("mychannel2")
	defer pubsub.Close()

	for i := 0; i < 2; i++ {
		// ReceiveTimeout is a low level API. Use ReceiveMessage instead.
		msgi, err := pubsub.ReceiveTimeout(time.Second)
		if err != nil {
			break
		}

		switch msg := msgi.(type) {
		case *redis.Subscription:
			fmt.Println("subscribed to", msg.Channel)

			_, err := redisdb.Publish("mychannel2", "hello").Result()
			if err != nil {
				panic(err)
			}
		case *redis.Message:
			fmt.Println("received", msg.Payload, "from", msg.Channel)
		default:
			panic("unreached")
		}
	}

	// sent message to 1 redisdb
	// received hello from mychannel2
}
Output:

func (*PubSub) ReceiveMessage

func (c *PubSub) ReceiveMessage() (*Message, error)

ReceiveMessage returns a Message or error ignoring Subscription and Pong messages. This is low-level API and in most cases Channel should be used instead.

func (*PubSub) ReceiveTimeout

func (c *PubSub) ReceiveTimeout(timeout time.Duration) (interface{}, error)

ReceiveTimeout acts like Receive but returns an error if message is not received in time. This is low-level API and in most cases Channel should be used instead.

func (*PubSub) Subscribe

func (c *PubSub) Subscribe(channels ...string) error

Subscribe the client to the specified channels. It returns empty subscription if there are no channels.

func (*PubSub) Unsubscribe

func (c *PubSub) Unsubscribe(channels ...string) error

Unsubscribe the client from the given channels, or from all of them if none is given.

type Ring

type Ring struct {
	// contains filtered or unexported fields
}

Ring is a Redis client that uses constistent hashing to distribute keys across multiple Redis servers (shards). It's safe for concurrent use by multiple goroutines.

Ring monitors the state of each shard and removes dead shards from the ring. When shard comes online it is added back to the ring. This gives you maximum availability and partition tolerance, but no consistency between different shards or even clients. Each client uses shards that are available to the client and does not do any coordination when shard state is changed.

Ring should be used when you need multiple Redis servers for caching and can tolerate losing data when one of the servers dies. Otherwise you should use Redis Cluster.

func NewRing

func NewRing(opt *RingOptions) *Ring
Example
package main

import (
	"github.com/go-redis/redis"

	Cmdable
	Watch(fn func(*Tx) error, keys ...string) error
	Process(cmd Cmder) error
	WrapProcess(fn func(oldProcess func(cmd Cmder) error) func(cmd Cmder) error)
	Subscribe(channels ...string) *PubSub
	PSubscribe(channels ...string) *PubSub
	Close() error
}

UniversalClient is an abstract client which - based on the provided options - can connect to either clusters, or sentinel-backed failover instances or simple single-instance servers. This can be useful for testing cluster-specific applications locally.

func NewUniversalClient

func NewUniversalClient(opts *UniversalOptions) UniversalClient

NewUniversalClient returns a new multi client. The type of client returned depends on the following three conditions:

1. if a MasterName is passed a sentinel-backed FailoverClient will be returned 2. if the number of Addrs is two or more, a ClusterClient will be returned 3. otherwise, a single-node redis Client will be returned.

Example (Cluster)
package main

import (
	"github.com/go-redis/redis"
)

func main() {
	redisdb := redis.NewUniversalClient(&redis.UniversalOptions{
		Addrs: []string{":7000", ":7001", ":7002", ":7003", ":7004", ":7005"},
	})
	defer redisdb.Close()

	redisdb.Ping()
}
Output:

Example (Failover)
