This tutorial uses @upstash/redis which is
designed for serverless runtimes for efficient connection handling. You can
use your favorite Redis client, but you may have to deal with connection
issues as described
here.
Create a Redis database using Upstash Console or
Upstash CLI. Select the GCP US-Central-1 as
the region. Copy the UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN for
the next steps.
