While I haven’t been able to produce a minimal reproduction today, I was able to get a working workaround. It would build fine, but running and visiting the demo server would produce the same memory error reported by @anburocky3

I added the troublesome module (lodash in my case) to the noExternal list in the nuxt.config and this seemed to resolve the issue.

nuxt.config.ts

export default defineNuxtConfig({
    vite: {
        ssr: {
          noExternal: ['lodash']
        }
    }
})

I found this problem when using the crypto JS library

NidMo on Apr 20, 2022

Having crypto-js as a dependency for a server route, I also had this error and I resolved it by allowing viteNode in the nuxt.config file :

  experimental: {
    viteNode: true
  },

I also needed to add .js for my crypto-js imports, for example : import cryptoAES from 'crypto-js/aes.js

I was seeing the same problem. In my case, it’s because I’m using vue3-datepicker. I don’t understand why a date picker package makes the engine run out of memory. Currently, my solution is not to use the vue3-datepicker.

I no longer see this error, might be seeing it randomly, will close this for now, if i have any problem in the future, will reopen it.

@oyed Thanks for your response.

anburocky3 on Apr 19, 2022

As the error says, the JS heap ran out of memory - to increase it, try adding this env var: NODE_OPTIONS="--max_old_space_size=4096"

You can prepend it to your package.json scripts, i.e. "build": "NODE_OPTIONS=\"--max_old_space_size=4096\" nuxi build"
