Nuxt Plugin using `useCookie` composable error.

Hi, I have a custom Auth fetch nuxt Plugin for fetching data behind a authentication. But I keep getting errors about using Nuxt composables. I am using the useCookie composable. How should I run this function?: Error:

 [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.

My custom fetch plugin:

import { useAuthStore } from '~/store/auth';

export default defineNuxtPlugin((nuxtApp) => {
    const config = useRuntimeConfig()
    const store= useAuthStore()

    const $authFetch = $fetch.create({
        baseURL: config.public.apiBaseURL,
        onRequest: async function ({request, options, error}) {

            let userSession = useCookie('authToken').value;

            if(!userSession?.token || (!userSession?.expiration || new Date(userSession.expiration) <= new Date())) {
                console.log("RETRIEVE A NEW TOKEN PLEASE:")
                const refreshed = await store.refreshTokenAction();
                if(!refreshed) throw new Error('Token refresh failed. Aborting request.');
            }
            // Retrieve again, I could use refreshCookie()
            userSession = useCookie('authToken').value;

            if (userSession.token) {
                options.headers = options.headers || {}
                options.headers.Authorization = `Bearer ${userSession.token}`
            }
        },
        onRequestError({ request, options, error }) {
        },
        onResponseError({ request, response, options }) {
        }
        })
    return { provide: { authFetch: $authFetch }
    }
})

import { useAuthStore } from '~/store/auth';

export default defineNuxtPlugin((nuxtApp) => {
    const config = useRuntimeConfig()
    const store= useAuthStore()

    const $authFetch = $fetch.create({
        baseURL: config.public.apiBaseURL,
        onRequest: async function ({request, options, error}) {

            let userSession = useCookie('authToken').value;

            if(!userSession?.token || (!userSession?.expiration || new Date(userSession.expiration) <= new Date())) {
                console.log("RETRIEVE A NEW TOKEN PLEASE:")
                const refreshed = await store.refreshTokenAction();
                if(!refreshed) throw new Error('Token refresh failed. Aborting request.');
            }
            // Retrieve again, I could use refreshCookie()
            userSession = useCookie('authToken').value;

            if (userSession.token) {
                options.headers = options.headers || {}
                options.headers.Authorization = `Bearer ${userSession.token}`
            }
        },
        onRequestError({ request, options, error }) {
        },
        onResponseError({ request, response, options }) {
        }
        })
    return { provide: { authFetch: $authFetch }
    }
})

example page that retrieves the data using the authFetch.

<script lang="ts" setup>
    const { data, error } = await useAuthFetch(`user/blog/${blogGuid}`);

<script lang="ts" setup>
    const { data, error } = await useAuthFetch(`user/blog/${blogGuid}`);

Does somebody know how I can fix this? This might be a SRR issue?

Most likely it’s propagating from useCookie which accesses the Nuxt instance on the server. I would move it to the top level out of the callback.

Thanks for having a look. Sadly putting the useCookie to the top level like this did not fix the problem:

export default defineNuxtPlugin((nuxtApp) => {
    const config = useRuntimeConfig()
    const store = useAuthStore()

    // Function to ensure we have a valid token
    const ensureValidToken = async () => {
        const authTokenCookie = useCookie('authToken')
        let userSession = authTokenCookie.value

        if (!userSession?.token || (!userSession?.expiration || new Date(userSession.expiration) <= new Date())) {
            console.log("RETRIEVE A NEW TOKEN PLEASE:")
            const refreshed = await store.refreshTokenAction()
            if (!refreshed) {
                throw new Error('Token refresh failed.')
            }
            // Get the updated cookie value after refresh
            userSession = useCookie('authToken').value
        }

        return userSession.token
    }

    const $authFetch = $fetch.create({
        baseURL: config.public.apiBaseURL,
        async onRequest({ request, options }) {
            const token = await ensureValidToken()
            options.headers = {
                ...options.headers,
                Authorization: `Bearer ${token}`
            }
        },
        onRequestE.................

Some context: I am using a jwt auth endpoint on a custom nodeJS server, so I am not using the nuxt auth package or SSR functionality (server folder). When setting the ssr to false in the nuxt.config.ts this works perfectly fine. But of course I don't want to lose out on SSR in some pages/components.

SSR does not require the use of the server directory. It works with SSR disabled because of the very issue I outlined. Lastly, I don’t see, in your revised code, useCookie moved to the top. It should be within the scope of the plugin, where you’ve placed your config and store.

Thanks a lot, I did manage to fix the composable problem (example below). Now I need to find out why the authToken.value is empty after a refreshCookie() 😂 probably again a SSR or browser thing, since the refreshToken is for the browser.

    export default defineNuxtPlugin((nuxtApp) => {

    const config = useRuntimeConfig()
    const store= useAuthStore()
    const authToken = useCookie('authToken');

    const $authFetch = $fetch.create({
        baseURL: config.public.apiBaseURL,
        onRequest: async function ({request, options, error}) {
            let userSession = authToken.value;

            if(!userSession?.token || (!userSession?.expiration || new Date(userSession.expiration) <= new Date())) {
                console.log("RETRIEVE A NEW TOKEN PLEASE:")
                const refreshed = await store.refreshTokenAction();
                if(!refreshed) throw new Error('Token refresh failed. Aborting request.');
            }
            // Retrieve again, I could use refreshCookie()
            refreshCookie('authToken');
            console.log('auth token from (refreshed) cookie:', authToken.value);

    export default defineNuxtPlugin((nuxtApp) => {

    const config = useRuntimeConfig()
    const store= useAuthStore()
    const authToken = useCookie('authToken');

    const $authFetch = $fetch.create({
        baseURL: config.public.apiBaseURL,
        onRequest: async function ({request, options, error}) {
            let userSession = authToken.value;

            if(!userSession?.token || (!userSession?.expiration || new Date(userSession.expiration) <= new Date())) {
                console.log("RETRIEVE A NEW TOKEN PLEASE:")
                const refreshed = await store.refreshTokenAction();
                if(!refreshed) throw new Error('Token refresh failed. Aborting request.');
            }
            // Retrieve again, I could use refreshCookie()
            refreshCookie('authToken');
            console.log('auth token from (refreshed) cookie:', authToken.value);

Well of course I can fix this with just returning the authToken when calling the refreshTokenAction function. But I am just curious how the flow is working now in Nuxt, this is an aspect I'm having difficulty wrapping my head around.
