Core Concepts

# Caching Images

[Copy for LLMs](https://nuxtseo.com/docs/og-image/v5/guides/cache.md)

In cases where you need to generate images at runtime, Nuxt OG Image provides a caching layer to reduce the load on your server.

This caching layer uses SWR caching is enabled by default with a cache time of 72 hours.

## [Cache Storage](#cache-storage)

Nitro caching by default will use the memory as a cache storage. This means that if you restart your server, the cache will be cleared.

It's recommended to set a persistent cache storage. This can be done using the `runtimeCacheStorage` option.

The option takes the same configuration as the Nuxt `nitro.storage` option. See the [Nitro Storage Layer](https://nitro.unjs.io/guide/storage) documentation for more details.

For example:

```
export default defineNuxtConfig({
  ogImage: {
    // cloudflare kv binding example, set your own config
    runtimeCacheStorage: {
      driver: 'cloudflare-kv-binding',
      binding: 'OG_IMAGE_CACHE'
    }
  }
})
```

## [Cache Time](#cache-time)

You can change the cache time of an image by providing `cacheMaxAgeSeconds` in milliseconds when defining the image.

```
defineOgImage({
  cacheMaxAgeSeconds: 30 // 30 seconds
})
```

Alternatively, you can change the default cache time in your nuxt.config.

nuxt.config.ts

```
export default defineNuxtConfig({
  ogImage: {
    defaults: {
      cacheMaxAgeSeconds: 60 * 60 * 24 * 7 // 7 days
    }
  }
})
```

## [Purging the cache](#purging-the-cache)

If you need to purge the cache, you can do so by visiting the OG Image URL appended with a `?purge` query param.

For example, to purge the OG Image cache for this page you could visit:

```
https://nuxtseo.com/__og-image__/image/og-image/guides/cache/og.png?purge
```

## [Bypassing the cache](#bypassing-the-cache)

While not recommended, if you prefer to opt-out of caching, you can do so by providing a `0` second `cacheMaxAgeSeconds` or disabling `runtimeCacheStorage`.

Disable single caching

Disable all caching

```
<script lang="ts" setup>
defineOgImage({
  cacheMaxAgeSeconds: 0 // disable at an individual image level
})
</script>
```

```
export default defineNuxtConfig({
  ogImage: {
    // disable at a global level
    runtimeCacheStorage: false,
  }
})
```
