Static Cache

However, the usage of static cache is limited. While it's ideal for achieving high speed on non-authenticated user pages like the home page, it is rarely applicable in other scenarios. For instance, using a static cache for a dashboard is not feasible since authentication is required for accessing personalized user data.

Use Cases

Static cache is an excellent choice for creating a sitemap that needs updating at most once a day. Developers commonly utilize it for JSON APIs that prioritize fast response times.

This caching method is particularly suitable when the data being served remains relatively unchanged and is not influenced by nor depends on the specific user requesting the information.

Example

For example, if you were to build a currency exchange rates API, you might want to fetch data from the database at most once a minute, not more often.

app/views/pages/currencies.json.liquid

static_cache:
  expire: 60 # response will be cached for 60 seconds (or 1 minute)
