Basic Key-Value Operations

This feature allows you to perform basic key-value operations such as setting and getting values from the Redis store.

const { createClient } = require('@redis/client');

(async () => {
  const client = createClient();
  await client.connect();

  await client.set('key', 'value');
  const value = await client.get('key');
  console.log(value); // Output: 'value'

  await client.disconnect();
})();

Data Structures

This feature allows you to manage complex data structures like lists. The example demonstrates how to push values to a list and retrieve them.

const { createClient } = require('@redis/client');

(async () => {
  const client = createClient();
  await client.connect();

  await client.lPush('list', 'value1');
  await client.lPush('list', 'value2');
  const list = await client.lRange('list', 0, -1);
  console.log(list); // Output: ['value2', 'value1']

  await client.disconnect();
})();

Pub/Sub Messaging

This feature allows you to use Redis's pub/sub messaging capabilities. The example shows how to publish a message to a channel and subscribe to that channel to receive messages.

const { createClient } = require('@redis/client');

(async () => {
  const publisher = createClient();
  const subscriber = createClient();

  await publisher.connect();
  await subscriber.connect();

  await subscriber.subscribe('channel', (message) => {
    console.log(message); // Output: 'Hello, World!'
  });

  await publisher.publish('channel', 'Hello, World!');

  // Give some time for the message to be received
  setTimeout(async () => {
    await publisher.disconnect();
    await subscriber.disconnect();
  }, 1000);
})();
