Build an application using Go

Prerequisites

This tutorial assumes that you have:

installed YugabyteDB, created a universe, and are able to interact with it using the Redis shell. If not, please follow these steps in Quick start.
installed Go version 1.8 or later

Install the Go Redis driver

To install the driver, locally run the following go get command.

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

Write a HelloWorld Go application

Create a file ybredis_hello_world.go and copy the contents below.

package main;

import (
  "fmt"
  "log"

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

func main() {
  // Connect to the cluster.
  client := redis.NewClient(&redis.Options{
    Addr:     "localhost:6379",
    Password: "", // no password set
    DB:       0,  // use the default DB
  })
  defer client.Close()

  // Insert some data (for user id 1).
  var userid string = "1"
  ok, err := client.HMSet(userid, map[string]interface{}{
        "name": "John",
        "age": "35",
        "language": "Redis"}).Result()

  if (err != nil) {
    log.Fatal(err)
  }
  fmt.Printf("HMSET returned '%s' for id=%s with values: name=John, age=35, language=Redis\n", ok, userid)

  // Query the data.
  result, err := client.HGetAll("1").Result()
  fmt.Printf("Query result for id=%s: '%v'\n", userid, result)
}

Run the application

To execute the file, run the following command.

$ go run ybredis_hello_world.go

You should see the following as the output.

HMSET returned 'OK' for id=1 with values: name=John, age=35, language=Redis
Query result for id=1: 'map[age:35 language:Redis name:John]'
