Dynamic Links in Subfolders not Working Properly with Routes

[d-kirkland]

Hi. I have a problem with dynamic links in subfolders in the pages directory. I have gone through the documentation a number of times, and I have not been able to solve this, so I am posting the question here.
I have a repository with the problem here: https://github.com/d-kirkland/i18n-dynamic-link-problem

The problem: I have a link on the index.vue page that should direct to pages/customers/challenges/[slug].vue. I have set up the routes like so:

'customer/challenges/[slug]': {
        en: '/customers/challenges/[slug]',
        de: '/kunden/challenges/[slug]',
    },

And the link looks like this:

<NuxtLink :to="localePath({ name: 'customers-challenges-slug', params: { slug: currentRoute }})"> {{ t('links.challenge') }} </NuxtLink>

The problem is that when I click on the link when I am the EN locale, I am directed to /en/customers/challenges/food. That is not a problem, but when I click on the link in the DE locale, I am directed to /de/customers/challenges/lebensmittel. This is where the problem is. I would expect the link in the DE locale to link to /de/kunden/challenges/lebensmittel. NuxtLink/localePath is picking up the slug, but it is not getting the route correct. I have provided all of the content of the files, and the link to the repository is above. Is there something that I am doing wrong?

Here is the index.vue page:

script setup lang="ts">
    const { localeProperties, setLocale } = useI18n()
    const localePath = useLocalePath()
    const { t } = useI18n({ inheritLocale: true })
    const source = {
        en: {
            route: 'food'
        },
        de: {
            route: 'lebensmittel'
        }
    }
    const code = localeProperties.value.code
    const currentRoute = computed(() => {
        if (localeProperties.value.code === 'de') return source.de.route
        else return source.en.route
    })
</script>

<template>
    <div>
        <div class="flex justify-center my-6">
            <NuxtLink :to="localePath({ name: 'customers-challenges-slug', params: { slug: currentRoute }})">{{ t('link.name') }}</NuxtLink>
        </div>
        <div class="flex justify-center my-10 gap-x-10">
            <button @click="setLocale('en')">en</button>
            <button @click="setLocale('de')">de</button>
        </div>
    </div>
</template>

<i18n lang="yaml">
    en:
        link: 
            name: Challenges
    de:
        link: 
            name: Herausforderungen
</i18n>

I am pulling the data in from a headless CMS, so the source object is meant as a substitute from data from the CMS.

There is then a pages/customers/challenges/[slug].vue page that looks like this:

<script setup lang="ts">
    const { t } = useI18n({ inheritLocale: true })
</script>

<template>
    <h1>{{ t('welcome')}}</h1>
</template>

<i18n lang="yaml">
    en: 
        welcome: Welcome to the Challenge 
    de:
        welcome: Willkommen zur Herausforderung
</i18n>

Then the nuxt.config.ts file:

import pages from './locales/routes'

export default defineNuxtConfig({
    compatibilityDate: '2024-04-03',
    devtools: { enabled: true },
    modules: [
        '@nuxtjs/i18n',
        '@nuxtjs/tailwindcss',
    ],
    i18n: {
        locales: [
            {
                code: 'en',
                iso: 'en-DE',
                languageCode: 'EN',
                countryCode: 'US',
                regionCode: 'EU',
                countryName: 'United States',
                currency: 'EUR',
            },
            {
                code: 'de',
                iso: 'de-DE',
                languageCode: 'DE',
                countryCode: 'DE',
                regionCode: 'EU',
                countryName: 'Deutschland',
                currency: 'EUR',
            },
        ],
        defaultLocale: 'en',
        strategy: 'prefix',
        detectBrowserLanguage: false,
        pages: pages,
        customRoutes: 'config',
    },
})

And then the locales/routes/index.js file:

const pages = {
    'index': {
        en: '/',
        de: '/',
    },
    'customer/challenges/index': {
        en: '/customers/challenges',
        de: '/kunden/challenges',
    },
    'customer/challenges/[slug]': {
        en: '/customers/challenges/[slug]',
        de: '/kunden/challenges/[slug]',
    },
}
export default pages;

package.json:

{
  "name": "nuxt-app",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "dependencies": {
    "@nuxtjs/i18n": "^8.5.1",
    "nuxt": "^3.13.0",
    "vue": "latest"
  },

  "devDependencies": {
    "@nuxtjs/tailwindcss": "^6.12.1"
  }
}

The issue in your reproduction appears to be that you're not using the route names in the pages configuration object, so the custom route paths are not applied.

const pages = {
    'index': {
        en: '/',
        de: '/',
    },
    // use route name
-  'customer/challenges/index': {
+  'customers-challenges': {
        en: '/customers/challenges',
        de: '/kunden/challenges',
    },
    // use route name
-   'customer-challenges-slug': {
+   'customers-challenges-slug': {
        en: '/customers/challenges/[slug]',
        de: '/kunden/challenges/[slug]',
    },
}
export default pages;

Sorry for the late response! Perhaps you already resolved this issue on your own, but if you have any questions let me know and I'll reopen this issue 🙏
