Mutation in nested components

With a complex UI, it happens quite often that a component which triggers a mutation is buried deep down a components tree. For now I have used the useMutation hook in the very same component which triggers the mutation. However, after a while of not developing a part of code, I find it really hard to remember which component contained the mutation.

Do you use any kind of convention with complex UIs in regards to where you put your useMutation hooks?

I am considering creating an intermediary component which would contain my “update” and “delete” mutations, which in turn would be called by callbacks passed to child components. However, before I spend some additional time on the refactoring, I would really appreciate to know if anyone else has implemented different approach and wanted to share their experience.

Just make global with all gql queries. This will achieve 2 things:

  1. All your query names will be unique
  2. You will have simple autocomplete on demand
  3. If you need to do some optimizations or changes, you have a single point to visit to make modifications to queries.

The reason you need to make sure all your query names are unique is to take full advantage of refetchQueries options. Something like this:

// Refetches two queries after mutation completes
const [addTodo, { data, loading, error }] = useMutation(repository.addToDo, {
  refetchQueries: [
    GET_POST, // DocumentNode object parsed with gql
    'GetPosts' // Query name

And there are 0 issues with having some repository imported where you need it.

If you want to be fancy you can create a hook that can handle communication with apollo so all you call are methods returned by hook.
