How to ensure nuxt doesn't run out of memory?

I have a blog with a lot of pages running with SWR (I don't want it to be static) but eventually the deployment runs out of memory, is there a way I can make sure it only stores 200 pages max in memory?

Hi @Lewis. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address the issue of Nuxt running out of memory for your blog with many pages using SWR (stale-while-revalidate), there are a few approaches you can consider: 1. Use LRU Cache: You can implement an LRU (Least Recently Used) cache to limit the number of pages stored in memory. Nuxt supports the use of LRU Cache through the unstorage package. Here's how you can set it up: 
   import { createStorage } from "unstorage";
   import lruCacheDriver from "unstorage/drivers/lru-cache";

   const storage = createStorage({
     driver: lruCacheDriver({ max: 200 }), // Limit to 200 items
   });
   
   import { createStorage } from "unstorage";
   import lruCacheDriver from "unstorage/drivers/lru-cache";

   const storage = createStorage({
     driver: lruCacheDriver({ max: 200 }), // Limit to 200 items
   });
This setup will ensure that only the 200 most recently used pages are kept in memory. Unstorage LRU Cache provides more details on this approach. 2. Adjust Node.js Memory Limit: If you're deploying to a server where you have control over the Node.js environment, you can increase the memory limit. Add this to your package.json scripts: 
   "build": "NODE_OPTIONS='--max-old-space-size=4096' nuxt build",
   "generate": "NODE_OPTIONS='--max-old-space-size=4096' nuxt generate"
   
   "build": "NODE_OPTIONS='--max-old-space-size=4096' nuxt build",
   "generate": "NODE_OPTIONS='--max-old-space-size=4096' nuxt generate"
This increases the Node.js memory limit to 4GB. Adjust the value as needed based on your server's capabilities. Github Issue Comment suggests this approach. 3. Optimize Webpack Configuration: You can optimize the Webpack configuration in your nuxt.config.js to reduce memory usage during build: 
   export default {
     webpack: {
       optimization: {
         minimize: true,
         splitChunks: {
           chunks: 'all',
           automaticNameDelimiter: '.',
           name: undefined,
           cacheGroups: {}
         }
       }
     }
   }
   
   export default {
     webpack: {
       optimization: {
         minimize: true,
         splitChunks: {
           chunks: 'all',
           automaticNameDelimiter: '.',
           name: undefined,
           cacheGroups: {}
         }
       }
     }
   }
This configuration can help reduce the memory footprint. More details on Webpack optimization can be found in the Nuxt Configuration Documentation. 4. Use Hybrid Rendering: Instead of using SWR for all pages, consider using hybrid rendering. This allows you to set different caching strategies for different routes. For example: 
   export default defineNuxtConfig({
     routeRules: {
       '/': { prerender: true },
       '/blog': { swr: 3600 },
       '/blog/**': { swr: 3600 }
     }
   })
   
   export default defineNuxtConfig({
     routeRules: {
       '/': { prerender: true },
       '/blog': { swr: 3600 },
       '/blog/**': { swr: 3600 }
     }
   })
This approach, detailed in the Nuxt Hybrid Rendering Documentation, can help reduce the memory load by prerendering some pages and using SWR for others. Remember, the effectiveness of these solutions may vary depending on your specific setup and deployment environment. You might need to combine multiple approaches to achieve the best result for your high-volume blog. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
