Redis

Hosting Redis on Fly is nice. node-resque is great for background jobs. Redcon is nice Redis based server.

I use Upstash as a serverless Redis.

Mini Redis is nice code to read to understand Redis internals.

Code

// rename keys
const keys = await redis.keys("*");
for (const key of keys) {
  if (key.includes("cache:")) {
    await redis.rename(key, key.replace("cache:", ""));
  }
}

Notes

• Redis is great for shared memory across service instances. Solves the 'how can I make every instance of this app aware of something' problem. Examples: Session store backed by redis. Cache layer backed by redis. Async atomic Job queue.
