Tell us about your experience using Redis Stack in projects.

Redis Stack is an extension of the classic Redis that adds support for additional data types and features such as full-text search, graphs, JSON, key expiration, and more.

In projects, I used Redis Stack for caching complex data structures and quick searching through them. For example, I stored JSON documents with user information and used the built-in search module for fast filtering by fields.

Example of using Redis Stack with JSON:

const redis = require('redis');
const client = redis.createClient();

async function run() {
  await client.connect();

  // Save a JSON document
  await client.json.set('user:1', '$', {name: 'Ivan', age: 30, city: 'Moscow'});

  // Get a field from JSON
  const name = await client.json.get('user:1', {path: '$.name'});
  console.log(name); // 'Ivan'

  await client.quit();
}

run();

This allows efficient working with data without resorting to complex transformations.
