[nuxt] A composable that requires access to the Nuxt instance was called outside of a plugin, Nuxt hook, Nuxt middleware, or Vue setup function. This is probably not a Nuxt bug. Find out more at `https://nuxt.com/docs/guide/concepts/auto-imports#vue-and-nuxt-composables`. about nuxt HOT 6 CLOSED

@xuzhihui123 composables are runtime only, if you want to use a composable in plugin you have to make sure it's running on client side only. you can achive that by adding .client to your plugin name (test.client.ts) or wapping it around onNuxtReady

onNuxtReady(async () => {
    await a();
})

thanks, Is there any other way to run it on the server side?

from nuxt.

Because I want to set some values after requesting some data from the server, which happens in server-side rendering, not just client-side rendering

Hello, you need to set the nuxt context with nuxtApp.runWithContext. useState is a composable that requires the nuxt context to be accessible

see https://nuxt.com/docs/guide/going-further/nuxt-app#the-nuxt-context

ok, solved it，thanks
