Set fetched data as options on nuxt.config

I'm working with nuxt 3, is there any way in which I can automatically set options for a module?

I want to fetch the active locales and the default locale I set up in Strapi, and automatically set those in the i18n module.

export default defineNuxtConfig({
  modules: [
    '@nuxtjs/i18n',
    '@nuxtjs/strapi'
  ],
  i18n: {
    strategy: 'prefix_except_default',
    locales: [ // locales would be fetched from Strapi endpoint
      {
        code: 'en',
        file: 'en.json'
      },
      {
        code: 'it',
        file: 'it.json'
      },
    ],
    langDir: 'assets/i18n',
    defaultLocale: 'en', // default locale would be fetched from Strapi endpoint
  },
})

I tried to import them with a plugin, but I can't sort it out, I guess there are better methods to do what I need to do

You can combine i18n plugin with pinia store.

stores/index.js

import { defineStore } from "pinia";
import { useFetch } from "#app";
    
const fetchDataByLocale = async (locale, headers) => {
    const res = await useFetch('http://<STRAPI_URL>/api/posts', {
        headers,
        params: {
            locale
        }
    });

    if (res.error.value) {
        throw createError({
            statusCode: res.error.value.statusCode,
            statusMessage: res.error.value.statusMessage
        });
    }

    return res.data;
};

export const useStore = defineStore("store", {
    state: () => ({
        data: {
            en: [],
            it: []
        }
    }),
    actions: {
        async fetchData() {
            const token = "<STRAPI_TOKEN>";
            const headers = {
                Authorization: `Bearer ${token}`
            };

            this.data.en = await fetchDataByLocale('en', headers);
            this.data.it = await fetchDataByLocale('it', headers);

        }
    },
    getters: {
        getData(state) {
            return state.data;
        }
    }
});

plugins/i18n.ts

import { createI18n } from 'vue-i18n'
import { useStore } from '~/stores/index.js'
import { storeToRefs } from 'pinia';

export default defineNuxtPlugin(async ({ vueApp }) => {
    const store = await useStore();
    await store.fetchData();
    const locales = storeToRefs(store.getData);
    const defaultLocale = "en"
    const i18nInstance = createI18n({
        legacy: false,
        globalInjection: true,
        locale: defaultLocale,
        locales: locales
    });
    vueApp.use(i18nInstance);
});

sampleComponent.vue:

<template>
    <div>
        <button @click="changeLocale('en')">English</button>
        <button @click="changeLocale('it')">Italian</button>
        <pre>{{ currentData }}</pre>
    </div>
</template>

<script>
import { useStore } from '~/stores/index.js';
export default {
    setup() {
        const store = useStore();
        const currentLocale = ref('en');
        store.fetchData();
        const changeLocale = (locale) => {
            currentLocale.value = locale;
        };
        const currentData = computed(() => store.data[currentLocale.value]);
        return {
            currentData,
            changeLocale
        };
    }
};
</script>
