How Can I Browse or View the Values Stored in Redis?

To browse or view the values in Redis, we can use different tools and commands. These tools help us look at our Redis data easily. The Redis command-line interface, or CLI, is a strong tool. It lets us interact directly with the Redis database. We can run commands to get keys and values without any trouble. We can also use graphical user interface tools, or GUI tools. These tools give a friendlier way to explore the data in Redis.

In this article, we will look at several ways to view Redis data. We will talk about using the Redis CLI and some GUI tools. We will also show how to connect to Redis from different programming languages. We will explore Redis commands for looking at data. Lastly, we will answer some common questions about viewing Redis values. The main points we will cover are:

  • How to browse the values in Redis.
  • Tools we can use to browse values in Redis.
  • Using the Redis CLI to see stored values.
  • Best GUI tools for viewing Redis data.
  • Exploring Redis data with commands.
  • Connecting to Redis from a programming language to see values.
  • Common questions about viewing Redis values.

What Tools Can We Use to Browse Values in Redis?

Redis gives us many tools to help us browse and see stored values easily. Here are some popular choices:

  1. Redis CLI: This is the command-line tool that comes with Redis. It lets us talk to our Redis database directly. We can use commands like GET, SET, KEYS, and SCAN to see and change data. Here is an example of getting a value:

    redis-cli GET mykey

  2. RedisInsight: This is a strong GUI tool made by Redis Labs. It provides an easy-to-use interface for browsing Redis data, checking performance, and running commands. We can see data structures and how they relate to each other.

  3. RDM (Redis Desktop Manager): This desktop client works on many platforms. It lets us manage Redis databases easily. We can see keys, data types, and do CRUD operations using a simple interface.

  4. Medis: This is a modern GUI for Redis. It is open-source and works on macOS. It has features like key browsing, data editing, and checking performance.

  5. Another Redis Desktop Manager (ARDM): This is a simple but effective GUI for managing Redis databases. It lets us connect to many Redis instances, browse keys, and run commands.

  6. Custom Scripts: We can write scripts in different programming languages like Python, Node.js, or Java. We use Redis clients to browse values in a program way. For example, we can use Python’s redis library like this:

    import redis

r = redis.Redis(host='localhost', port=6379, db=0)
value = r.get('mykey')
print(value)

These tools help us easily see and manage our Redis data. This makes it better for us to interact and understand the stored values.

How Can We Use Redis CLI to View Stored Values?

To view values stored in Redis with the Redis Command Line Interface (CLI), we can follow these simple steps:

  1. Connect to Redis Server: First, we need to open our terminal. Then we run this command to connect to our Redis server. If needed, we can change localhost and 6379 to our server’s address and port.

    redis-cli -h localhost -p 6379

  2. List All Keys: Next, we can use the KEYS command to list all keys stored in Redis. This command shows all keys or keys that match a pattern.

    KEYS *

    To find specific keys, we can use a pattern like this:

    KEYS user:*

  3. Get Value of a Key: If we want to get the value for a specific key, we can use the GET command for string data types. Just replace your_key with the actual key.

    GET your_key

  4. View Hash Values: When we work with hashes, we can use the HGETALL command to get all fields and values in the hash.

    HGETALL your_hash_key

  5. List Values in a List: For lists, we can use the LRANGE command to get a range of elements from the list.

    LRANGE your_list_key 0 -1

  6. Retrieve Set Members: We can use the SMEMBERS command to get all members of a set.

    SMEMBERS your_set_key

  7. View Sorted Set Members: For sorted sets, we can use the ZRANGE command to get members in a certain range.

    ZRANGE your_sorted_set_key 0 -1

  8. Check Key Type: To find out the data type of a key, we can use the TYPE command.

    TYPE your_key

  9. Use Additional Commands: There are other helpful commands too. We can use SCAN to go through keys without blocking the server. We can use INFO to get server statistics.

    SCAN 0
INFO

These commands help us easily browse or view the values stored in Redis with the Redis CLI. For more details on using Redis commands, we can check the Redis CLI documentation.

What Are the Best GUI Tools for Viewing Redis Data?

How Can We Use Redis Commands to Explore Data?

To explore data in Redis, we can use different commands. These commands help us retrieve, inspect, and change data. Here are some key Redis commands to help us browse and see values:

  1. KEYS: We can get all keys that match a certain pattern.

    KEYS *
KEYS user:*    # This finds keys that start with 'user:'

  2. SCAN: This lets us go through keys one by one. It is good for big datasets.

    SCAN 0

  3. GET: We can get the value of a string key.

    GET mykey

  4. HGETALL: This command gets all fields and values in a hash.

    HGETALL myhash

  5. LRANGE: We can get elements from a list.

    LRANGE mylist 0 -1  # This retrieves all elements in the list

  6. SMEMBERS: This command gets all members of a set.

    SMEMBERS myset

  7. ZRANGE: We can retrieve elements in a sorted set by index.

    ZRANGE mysortedset 0 -1  # This gets all elements in sorted set

  8. TTL: We can check how long a key will live.

    TTL mykey

  9. EXISTS: This checks if a key is there.

    EXISTS mykey

  10. TYPE: We can get the type of a value stored at a key. bash TYPE mykey

These commands help us explore and manage our Redis data well. For more details on specific Redis commands and how to use them, we can check the Redis documentation.

How Can We Connect to Redis from a Programming Language to View Values?

To connect to Redis using a programming language, we can use special Redis clients that work with different languages. Below, we share examples of how we can connect to Redis and see values in popular programming languages.

Python

With the redis-py client, we can connect to Redis like this:

import redis

# Connect to Redis
client = redis.StrictRedis(host='localhost', port=6379, db=0)

# Retrieve a value
value = client.get('my_key')
print(value.decode('utf-8'))  # Decode bytes to string if we need

For more info on using Redis with Python, check Redis with Python.

Node.js

With the redis package, we can connect to Redis like this:

const redis = require('redis');

// Connect to Redis
const client = redis.createClient();

client.on('error', (err) => {
  console.log('Error ' + err);
});

// Retrieve a value
client.get('my_key', (err, reply) => {
  if (err) throw err;
  console.log(reply);
});

Look at Redis with Node.js for more details.

Java

Using the Jedis client, we can connect to Redis in Java like this:

import redis.clients.jedis.Jedis;

public class RedisExample {
    public static void main(String[] args) {
        // Connect to Redis
        Jedis jedis = new Jedis("localhost");

        // Retrieve a value
        String value = jedis.get("my_key");
        System.out.println(value);
        
        jedis.close();
    }
}

For a full guide, check Redis with Java.

PHP

With the Predis library, we can connect like this:

require "vendor/autoload.php";

$client = new Predis\Client();

// Retrieve a value
$value = $client->get('my_key');
echo $value;

Go

Using the go-redis package, we can connect in Go like this:

package main

import (
    "fmt"
    "github.com/go-redis/redis/v8"
    "context"
)

func main() {
    ctx := context.Background()
    client := redis.NewClient(&redis.Options{
        Addr: "localhost:6379",
    })

    // Retrieve a value
    val, err := client.Get(ctx, "my_key").Result()
    if err != nil {
        panic(err)
    }
    fmt.Println(val)
}
