MutationCache

Defined in: packages/vue-query/src/mutationCache.ts:15

Vue-aware subclass of @tanstack/query-core's MutationCache. find/findAll also accept a MaybeRefDeep filters object, so refs can be passed directly without unwrapping. Access it via queryClient.getMutationCache() — QueryClient constructs one of these by default.

Methods#

clear()#

clear(): void;

Defined in: packages/query-core/src/mutationCache.ts:236

Removes all mutations from the cache.

Returns#

void

Example#

const mutationCache = queryClient.getMutationCache()

mutationCache.clear()

Inherited from#

MC.clear

find()#

find<TData, TError, TVariables, TOnMutateResult>(filters): 
  | Mutation<TData, TError, TVariables, TOnMutateResult>
  | undefined;

Defined in: packages/vue-query/src/mutationCache.ts:16

A slightly more advanced method that can be used to get an existing mutation instance from the cache. If the mutation does not exist, undefined is returned.

This is not typically needed for most applications, but can come in handy when needing more information about a mutation in rare scenarios.

Type Parameters#

TData#

TData = unknown

TError#

TError = Error

TVariables#

TVariables = any

TOnMutateResult#

TOnMutateResult = unknown

Parameters#

filters#

MaybeRefDeep<MutationFilters<unknown, Error, unknown, unknown>>

Returns#

| Mutation<TData, TError, TVariables, TOnMutateResult> | undefined

See#

MutationCache#findAll

Example#

const mutationCache = queryClient.getMutationCache()

const mutation = mutationCache.find({ mutationKey: ['addPost'] })

Overrides#

MC.find

findAll()#

findAll(filters): Mutation<unknown, Error, unknown, unknown>[];

Defined in: packages/vue-query/src/mutationCache.ts:27

An even more advanced method that can be used to get existing mutation instances from the cache that match the given filters. If no mutations match, an empty array is returned.

This is not typically needed for most applications, but can come in handy when needing more information about mutations in rare scenarios.

Parameters#

filters#

MaybeRefDeep<MutationFilters<unknown, Error, unknown, unknown>> = {}

Returns#

Mutation<unknown, Error, unknown, unknown>[]

See#

MutationCache#find

Example#

const mutationCache = queryClient.getMutationCache()

const mutations = mutationCache.findAll({ mutationKey: ['addPost'] })

Overrides#

MC.findAll

getAll()#

getAll(): Mutation<unknown, Error, unknown, unknown>[];

Defined in: packages/query-core/src/mutationCache.ts:259

Returns all mutations within the cache.

This is not typically needed for most applications, but can come in handy when needing more information about a mutation in rare scenarios.

Returns#

Mutation<unknown, Error, unknown, unknown>[]

Example#

const mutationCache = queryClient.getMutationCache()

const mutations = mutationCache.getAll()
