isMutating(...)

This method returns an integer representing how many mutations are currently in the loading state. Refer to the TanStack queryClient.isMutating 🌴 guide for more information.

With filters

Checks if any mutations are fetching with the specified filters.

const mutationNumber = qraft.<service>.<operation>.isMutating(
  filters
)

Arguments

1. filters: UseMutationStateFiltersByParameters | UseMutationStateFiltersByMutationKey,
   • Required, represents the Mutation Filters 🌴 to be used, strictly-typed ✨
   • filters.parameters: { path, query, header } will be used for filtering mutations by parameters
   • filters.mutationKey: MutationKey will be used for filtering mutations by MutationKey instead of parameters
     • filters.mutationKey and filters.parameters are mutually exclusive
   • filters.predicate?: (mutation: Mutation) => boolean will be used for filtering mutations by custom predicate

Returns

mutationsNumber: The number of mutations that are matching the provided filters and are in the loading state

Without filters

Check all mutations for the specified endpoint.

const mutationNumber = qraft.<service>.<operation>.isMutating()

Returns

mutationsNumber: The number of all mutations matching to <service>.<operation> and are in the loading state

Examples

filters

Check if any mutations are pending with the specified parameters:

/**
* Checks if the mutation with the specified parameters is fetching:
* ###
* POST /entities/3e3e-3e3e-3e3e
* x-monite-version: 2023-09-01
**/
const numberOfFetchingEntities = qraft.entities.postEntities.isMutating(
  {
    header: {
      'x-monite-version': '2023-09-01',
    },
    path: {
      entity_id: '3e3e-3e3e-3e3e',
    },
  }
);

expect(numberOfFetchingEntities).toEqual(1);

To check all mutations status for a particular endpoint, you can call isMutating(...) without parameters:

/**
 * Checks mutations matching the specified endpoint:
 * ###
 * POST /entities/3e3e-3e3e-3e3e
 * x-monite-version: 2023-09-01
 * ###
 * POST /entities/4c4c-4c4c-4c4c
 * x-monite-version: 2023-09-01
 * ###
 * ⬇︎ All mutations for the specified endpoint will be used
 **/
const numberOfFetchingEntities = qraft.entities.postEntities.isMutating();

expect(numberOfFetchingEntities).toEqual(2);
