Caching

Caching improves performance by storing the results of expensive database queries and template renders in memory.

Setting up Redis as Cache Store

Spree comes pre-configured to use Redis for caching in production. Just set the REDIS_URL environment variable — no gem installation or code changes needed.

REDIS_URL=redis://localhost:6379/0

When REDIS_URL is set, Spree automatically uses it for caching. When not set, it falls back to an in-memory cache store.

Testing Locally

To enable caching in the development environment:

cd server
bin/rails dev:cache

You will need to restart your web server after this.
