• 👌 Enhancement (improving an existing functionality like performance)
• ✨ New feature (a non-breaking change that adds functionality)
• ⚠️ Breaking change (fix or feature that would cause existing functionality to change)

📚 Description

This PR is the equivalent of nuxt/framework#6864 for Nuxt Bridge to keep the project in alignment with Nuxt 3.

---

As this feature now goes beyond just auto-imports, the naming autoImports as become a bit confusing and ambiguous. See nuxt/framework#6768 for more. This PR renames Nuxt option autoImports to imports and hooks autoImports:* to imports:*. This also aligns with components option.

👉 Migration

⚠️ Breaking change: Nuxt option autoImports named to imports. Hooks autoImports:* renamed to imports:*.

for nuxt.config.ts:

  export default defineNuxtConfig({
    bridge: {
-     autoImports: true,
+     imports: true,
    },
-   autoImports: {
+   imports: {
      // 
    },
  })

for module authors:

-nuxt.hook('autoImports:extend', () => { })
+nuxt.hook('imports:extend', () => { })
