Features and limitations

• Supports simple use of lists, hashmaps, sets and key/values
• Deals mainly with strings
• Uses the redigo package

Example usage

package main

import (
    "log"

    "github.com/xyproto/simpleredis/v2"
)

func main() {
    // Check if the redis service is up
    if err := simpleredis.TestConnection(); err != nil {
        log.Fatalln("Could not connect to Redis. Is the service up and running?")
    }

    // Use instead for testing if a different host/port is up.
    // simpleredis.TestConnectionHost("localhost:6379")

    // Create a connection pool, connect to the given redis server
    pool := simpleredis.NewConnectionPool()

    // Use this for connecting to a different redis host/port
    // pool := simpleredis.NewConnectionPoolHost("localhost:6379")

    // For connecting to a different redis host/port, with a password
    // pool := simpleredis.NewConnectionPoolHost("password@redishost:6379")

    // Close the connection pool right after this function returns
    defer pool.Close()

    // Create a list named "greetings"
    list := simpleredis.NewList(pool, "greetings")

    // Add "hello" to the list, check if there are errors
    if list.Add("hello") != nil {
        log.Fatalln("Could not add an item to list!")
    }

    // Get the last item of the list
    if item, err := list.GetLast(); err != nil {
        log.Fatalln("Could not fetch the last item from the list!")
    } else {
        log.Println("The value of the stored item is:", item)
    }

    // Remove the list
    if list.Remove() != nil {
        log.Fatalln("Could not remove the list!")
    }
}

Testing

Redis must be up and running locally for the go test tests to work.

Timeout issues

If there are timeout issues when connecting to Redis, try consulting the Redis latency doctor on the server by running redis-cli and then latency doctor.
