v0.4.0

Highlights

• Published better-convex-nuxt@0.4.0.
• Adds and documents the supported shared query path with defineSharedConvexQuery.
• Cleans up stale query docs that referenced the old useLazyConvexQuery API.
• Keeps low-level query state internals private instead of exposing createConvexQueryState as public API.
• Exports ConvexUser from the module entrypoint so apps can use root module augmentation.
• Hardens starter apps, including MCP approval flow work and 0.4.0 package references.
• Updates the demo to the current callable mutation API (const mutate = useConvexMutation(...)).

Notes

• useConvexMutation is callable directly. The old .execute style is not part of the current public API.
• For middleware/plugins, continue using useConvexCall or server helpers instead of live query composables.

Validation

• Root package was already published to npm as 0.4.0.
• Demo typecheck and build pass against better-convex-nuxt@0.4.0.
• MCP starter lint and tests passed; typecheck and build passed. convex codegen requires a configured CONVEX_DEPLOYMENT and was not runnable in this local checkout.
• Starter generated-artifact guard passes.
