Redis

> In-memory data store.

---

When To Use

• Caching
• Sessions
• Real-time
• Rate limiting

---

What To Do

1. Connect

import { createClient } from 'redis'

const client = createClient({
  url: 'redis://localhost:6379'
})
await client.connect()

2. Operations

| Command | What | |---------|------| | get/set | String values | | hget/hset | Hash values | | lpush/lrange | Lists | | sadd/smembers | Sets | | publish | Pub/sub |

3. Patterns

// Cache
await client.set('user:1', JSON.stringify(user))
const user = JSON.parse(await client.get('user:1'))

// Session
await client.setex(`sess:${id}`, 3600, data)

// Rate limit
const count = await client.incr(`ratelimit:${key}`)

4. Use Cases

| Use | Benefit | |-----|----------| | Cache DB | Speed | | Session store | Speed | | Pub/Sub | Real-time | | Rate limit | Security |
