# Caching

> Configure caching for your Spree application

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.

```bash theme={"theme":"night-owl"}
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:

```bash theme={"theme":"night-owl"}
cd server
bin/rails dev:cache
```

You will need to restart your web server after this.
