Hi !
When will this PR be merged?
I'm interested in the axios example.

Refactored this to the current state of the project before merging: instead of the two full 2022 create-vue scaffolds under examples/ (which were mostly unmodified boilerplate and would have gone stale again immediately), the intent now lives as a Cookbook docs section with two maintained recipe pages:

• Vue Query: pinia-orm + TanStack Query v5 (@tanstack/vue-query object API) with a QueryRepository based on the BaseRepository pattern from this PR — queries persist into the store, components read normalized relational data.
• Axios: both the official @pinia-orm/axios plugin setup and the manual service-layer approach, using the v2 APIs (persistBy: 'fresh' etc.).

All examples use the 2.0.0 standard-decorator/model syntax.
