Redigo is a Go client for the Redis database. It offers a simple, efficient, and type-safe API for interacting with Redis, supporting various Redis commands and features. Redigo is widely used in Go applications for Redis integration.

Pros

• Simple and intuitive API
• High performance and efficient connection pooling
• Supports Redis pipelining and transactions
• Extensive documentation and community support

Cons

• Lacks some advanced features like automatic reconnection
• No built-in support for Redis Cluster
• Limited support for newer Redis features compared to some other clients
• Manual management of connections required in some cases

Code Examples

1. Basic connection and key-value operations:

conn, err := redis.Dial("tcp", "localhost:6379")
if err != nil {
    log.Fatal(err)
}
defer conn.Close()

_, err = conn.Do("SET", "key", "value")
if err != nil {
    log.Fatal(err)
}

value, err := redis.String(conn.Do("GET", "key"))
if err != nil {
    log.Fatal(err)
}
fmt.Println("Value:", value)

2. Using a connection pool:

pool := &redis.Pool{
    MaxIdle:     3,
    IdleTimeout: 240 * time.Second,
    Dial:        func() (redis.Conn, error) { return redis.Dial("tcp", "localhost:6379") },
}

conn := pool.Get()
defer conn.Close()

_, err := conn.Do("SET", "key", "value")
if err != nil {
    log.Fatal(err)
}

3. Pipelining commands:

conn, err := redis.Dial("tcp", "localhost:6379")
if err != nil {
    log.Fatal(err)
}
defer conn.Close()

conn.Send("SET", "key1", "value1")
conn.Send("SET", "key2", "value2")
conn.Send("GET", "key1")
conn.Send("GET", "key2")
conn.Flush()

for i := 0; i < 4; i++ {
    reply, err := conn.Receive()
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("Reply %d: %v\n", i, reply)
}

Getting Started

To use Redigo in your Go project, follow these steps:

1. Install Redigo:

   go get github.com/gomodule/redigo/redis
   

2. Import the package in your Go code:

   import "github.com/gomodule/redigo/redis"
   

3. Create a connection to Redis:

   conn, err := redis.Dial("tcp", "localhost:6379")
   if err != nil {
       log.Fatal(err)
   }
   defer conn.Close()
   

4. Start using Redis commands:

   _, err = conn.Do("SET", "mykey", "myvalue")
   if err != nil {
       log.Fatal(err)
   }
