react-query - What's the difference between useQuery and useMutation hook?

Trying to find an answer regarding react-query.

What's the difference between useQuery and useMutation?

From what I understand, useQuery's are dependent calls.

useMutation is for posts that require updating the current state (cache invalidation, etc.)

Is that the correct assumption?

Solution

  • From Tanner Linsley:

    The difference is the flow of data. useQuery is used to query async data, useMutation is used to mutate it. Or in the traditional CRUD speak:

    • Read: useQuery
    • Create/Update/Delete: useMutation
