cache

When using nuxt routerules and swr, is it possible to ingnore the query parameters when caching the page so that all pages with same path but different query parameters use the same cache?

Hi @Matthias. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, it is possible to ignore query parameters when caching pages using Nuxt route rules with SWR (stale-while-revalidate) caching strategy. This can be achieved by configuring the allowQuery option in the route rules. According to the Nitro documentation on fine-grained ISR config (https://nitro.unjs.io/deploy/providers/vercel#fine-grained-isr-config-via-route-rules), you can use the allowQuery option to control which query parameters are considered for caching: - If allowQuery is set to an empty array, query values are not considered for caching. - If allowQuery is undefined, each unique query value is cached independently. To ignore all query parameters and cache only based on the path, you can set allowQuery to an empty array. Here's an example of how you can configure this in your nuxt.config.ts:

export default defineNuxtConfig({
  routeRules: {
    '/products/**': {
      isr: {
        swr: true,
        allowQuery: [],
      },
    },
  },
})

export default defineNuxtConfig({
  routeRules: {
    '/products/**': {
      isr: {
        swr: true,
        allowQuery: [],
      },
    },
  },
})

In this example, all pages under the /products/ path will use the same cache, regardless of their query parameters. It's worth noting that while this example uses the isr (Incremental Static Regeneration) option, which is specific to certain deployment platforms like Vercel, the swr option works similarly for Nuxt's built-in caching mechanism. Nitro route rules documentation (https://nitro.unjs.io/guide/routing#route-rules) provides more information on configuring route rules, including caching options. Remember that the exact behavior might depend on your deployment platform and Nuxt version, so it's always a good idea to test your configuration to ensure it behaves as expected. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this is about isr not swr

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the confusion in my previous answer. You are correct, and I appreciate you pointing that out. Let me provide a more accurate response focusing on ISR (Incremental Static Regeneration) instead of SWR. ISR (Incremental Static Regeneration) is indeed different from SWR (Stale-While-Revalidate), although they share some similarities in caching behavior. For ISR in Nuxt, we can still control how query parameters affect caching. According to the Nitro documentation on fine-grained ISR config (https://nitro.unjs.io/deploy/providers/vercel#fine-grained-isr-config-via-route-rules), you can configure ISR to ignore query parameters when caching pages. Here's how you can do it:

export default defineNuxtConfig({
  routeRules: {
    '/products/**': {
      isr: {
        allowQuery: [],
      },
    },
  },
})

export default defineNuxtConfig({
  routeRules: {
    '/products/**': {
      isr: {
        allowQuery: [],
      },
    },
  },
})

In this configuration: - isr enables Incremental Static Regeneration for the specified route. - allowQuery: [] sets an empty array, which means query parameters will be ignored for caching purposes. This setup will ensure that all pages with the same path but different query parameters use the same cache when using ISR. It's important to note that ISR is typically used for deployment platforms that support this feature, such as Vercel or Netlify. The behavior might vary slightly depending on your hosting platform. For more information on Nuxt's hybrid rendering and route rules, including ISR, you can refer to the Nuxt documentation on Hybrid Rendering (https://nuxt.com/docs/guide/concepts/rendering#hybrid-rendering). Thank you for bringing this to my attention, and I hope this clarifies the ISR-specific approach to handling query parameters in caching. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai no, i mean your original answer was about isr, but i need something for swr

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the confusion in my previous responses. You're right, and I thank you for your patience. Let me provide you with the correct information specifically about SWR (Stale-While-Revalidate) caching in Nuxt route rules. For SWR caching in Nuxt, you can indeed configure it to ignore query parameters. Here's how you can set it up in your nuxt.config.ts:

export default defineNuxtConfig({
  routeRules: {
    '/products/**': { 
      swr: true,
      cache: {
        allowQuery: []
      }
    }
  }
})

export default defineNuxtConfig({
  routeRules: {
    '/products/**': { 
      swr: true,
      cache: {
        allowQuery: []
      }
    }
  }
})

In this configuration: - swr: true enables Stale-While-Revalidate caching for the specified route. - cache: { allowQuery: [] } sets an empty array for allowQuery, which means query parameters will be ignored for caching purposes. This setup will ensure that all pages with the same path but different query parameters use the same cache when using SWR. According to the Nitro caching guide (https://nitro.unjs.io/guide/cache#caching-route-rules), you can add caching routes based on a glob pattern directly in the main configuration file. This is useful for implementing a global cache strategy for a part of your application. It's worth noting that the swr option in route rules is actually a shortcut for setting up cache with SWR behavior. As mentioned in the Nitro route rules documentation (https://nitro.unjs.io/guide/routing#route-rules), swr: true|number is a shortcut for cache: { swr: true, maxAge: number }. Remember to test your configuration to ensure it behaves as expected in your specific use case. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
