Redis client for Golang

Build Status GoDoc Airbrake

Supports:

API docs: https://godoc.org/github.com/go-redis/redis. Examples: https://godoc.org/github.com/go-redis/redis#pkg-examples.

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()

// custom command
res, err := client.Do("set", "key", "value")
