Default useSsrCookies: true + ssr: false silently breaks SPA refresh; undocumented #605

Follow-up to #571 / #496 — the fix from #571 (released in v2.0.5) only triggers when useSsrCookies: false is explicitly set, leaving users on the default config still hitting the original symptom.

Version

@nuxtjs/supabase: v2.0.6
nuxt: v4.4.2

Steps to reproduce

1. Create a Nuxt 4 app with ssr: false.

2. Install @nuxtjs/supabase@2.0.6 with the default config — do not set useSsrCookies:

   export default defineNuxtConfig({
     ssr: false,
     modules: ['@nuxtjs/supabase'],
     supabase: {
       url: process.env.SUPABASE_URL,
       key: process.env.SUPABASE_KEY,
       redirectOptions: {
         login: '/login',
         callback: '/confirm',
         exclude: ['/login', '/confirm'],
       },
     },
   })

3. Add a /login page that calls supabase.auth.signInWithPassword and a protected route.

4. Sign in successfully — you land on the protected page.

5. Hard-refresh the browser.

What is Expected?

Either of:

• The user remains signed in on refresh in SPA mode without needing extra config, or
• The docs clearly prescribe the required SPA configuration. Currently useSsrCookies is mentioned only on the introduction page, with no reference to ssr: false, no "SPA / CSR-only" section, and no example pairing the two settings.

What is actually happening?

The user is redirected to /login on every refresh. The fix from #571 (released in v2.0.5) only runs when useSsrCookies: false is explicitly set:

if (!useSsrCookies) {
  const { data } = await client.auth.getSession()
  if (data.session) currentSession.value = data.session
}

With the default useSsrCookies: true and no SSR running, nothing populates currentSession synchronously, so the global auth-redirect middleware sees session.value === null and navigates to login before onAuthStateChange fires.

This same suggestion was made as a side note in #496 ("maybe it could use ssr flag from nuxt config as a default, instead of being true, while ssr is false") but doesn't appear to have been picked up.

Suggestions:

• Auto-default useSsrCookies to false when ssr === false in the Nuxt config, or
• Add an "SPA / CSR-only" section to the docs that prescribes ssr: false + useSsrCookies: false and explains why both are needed.
