--- id: migrating-to-tanstack-query-5 title: Migrating to TanStack Query v5 ref: docs/framework/react/guides/migrating-to-v5.md --- [//]: # 'FrameworkSpecificBreakingChanges' ## Vue Query Breaking Changes ### `useQueries` composable returns `ref` instead of `reactive` To fix compatibility with Vue 2, `useQueries` composable now returns `queries` array wrapped in `ref`. Previously `reactive` was returned which led to multiple problems: - User could spread return value loosing reactivity. - `readonly` wrapper used for return value was breaking Vue 2 reactivity detection mechanism. This was a silent issue in Vue 2.6, but appeared as error in Vue 2.7. - Vue 2 does not support arrays as a root value of `reactive`. With this change all of those issues are fixed. Also this aligns `useQueries` with other composables which return all of the values as `refs`. ### Vue v3.3 is now required To be able to provide new features following Vue releases, we now require Vue 3 to be at least in v3.3 version. Requirements for Vue 2.x remain unchanged. [//]: # 'FrameworkSpecificBreakingChanges' [//]: # 'FrameworkSpecificNewFeatures' ### Ability to run `vue-query` composables in `injectionContext` Previously `vue-query` composables could be run only within `setup` function of the component. We had an escape hatch in place to allow those hooks to be run anywhere if user would provide `queryClient` as a composable option. Now you can use `vue-query` composables in any function that supports `injectionContext`. Ex. router navigation guards. When using this new feature, make sure that `vue-query` composable is running within `effectScope`. Otherwise it might lead to memory leaks. We have added `dev-only` warnings to inform users about potential misusage. [//]: # 'FrameworkSpecificNewFeatures'
