mutation

TanStack Query parameters. See the TanStack Query mutation docs for more info.

Wagmi does not support passing all TanStack Query parameters

TanStack Query parameters, like mutationFn and mutationKey, are used internally to make Wagmi work and you cannot override them. Check out the source to see what parameters are not supported. All parameters listed below are supported.

gcTime

number | Infinity | undefined

• The time in milliseconds that unused/inactive cache data remains in memory. When a mutation's cache becomes unused or inactive, that cache data will be garbage collected after this duration. When different cache times are specified, the longest one will be used.
• If set to Infinity, will disable garbage collection

meta

Record<string, unknown> | undefined

If set, stores additional information on the mutation cache entry that can be used as needed. It will be accessible wherever disconnect is available (e.g. onError, onSuccess functions).

networkMode

'online' | 'always' | 'offlineFirst' | undefined

• defaults to 'online'
• see Network Mode for more information.

onError

((error: DisconnectErrorType, variables: { connector?: Connector | undefined; }, context?: context | undefined) => Promise<unknown> | unknown) | undefined

This function will fire if the mutation encounters an error and will be passed the error.

onMutate

((variables: { connector?: Connector | undefined; }) => Promise<context | void> | context | void) | undefined

• This function will fire before the mutation function is fired and is passed the same variables the mutation function would receive
• Useful to perform optimistic updates to a resource in hopes that the mutation succeeds
• The value returned from this function will be passed to both the onError and onSettled functions in the event of a mutation failure and can be useful for rolling back optimistic updates.

onSuccess

((data: void, variables: { connector?: Connector | undefined; }, context?: context | undefined) => Promise<unknown> | unknown) | undefined

This function will fire when the mutation is successful and will be passed the mutation's result.

onSettled

((data: void, error: DisconnectErrorType, variables: { connector?: Connector | undefined; }, context?: context | undefined) => Promise<unknown> | unknown) | undefined

This function will fire when the mutation is either successfully fetched or encounters an error and be passed either the data or error

queryClient

QueryClient

Use this to use a custom QueryClient. Otherwise, the one from the nearest context will be used.

retry

boolean | number | ((failureCount: number, error: DisconnectErrorType) => boolean) | undefined

• Defaults to 0.
• If false, failed mutations will not retry.
• If true, failed mutations will retry infinitely.
• If set to an number, e.g. 3, failed mutations will retry until the failed mutations count meets that number.

retryDelay

number | ((retryAttempt: number, error: DisconnectErrorType) => number) | undefined

• This function receives a retryAttempt integer and the actual Error and returns the delay to apply before the next attempt in milliseconds.
• A function like attempt => Math.min(attempt > 1 ? 2 ** attempt * 1000 : 1000, 30 * 1000) applies exponential backoff.
• A function like attempt => attempt * 1000 applies linear backoff.

Return Type

import { type UseDisconnectReturnType } from '@wagmi/vue'

connectors

readonly Connector[]

Connectors that are currently connected. Useful for rendering a list of connectors to disconnect.

index.vue

<script setup lang="ts">
import { useDisconnect } from '@wagmi/vue'
import { mainnet } from 'wagmi/chains'

const { connectors, disconnect } = useDisconnect()
</script>

<template>
  <div>
    <button v-for="connector in connectors" :key="connector.id" @click="disconnect({ connector })">
      {{ connector.name }}
    </button>
  </div>
</template>

config.ts

import { http, createConfig } from '@wagmi/vue'
import { mainnet, sepolia } from '@wagmi/vue/chains'

export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})

TanStack Query mutation docs

disconnect

(variables: { connector?: Connector | undefined; }, { onSuccess, onSettled, onError }) => void

The mutation function you can call with variables to trigger the mutation and optionally hooks on additional callback options.

• variables

  { connector?: Connector | undefined; }

  The variables object to pass to the disconnect action.

• onSuccess

  (data: void, variables: { connector?: Connector | undefined; }, context: TContext) => void

  This function will fire when the mutation is successful and will be passed the mutation's result.

• onError

  (error: DisconnectErrorType, variables: { connector?: Connector | undefined; }, context: TContext | undefined) => void

  This function will fire if the mutation encounters an error and will be passed the error.

• onSettled

  (data: void | undefined, error: DisconnectErrorType | null, variables: { connector?: Connector | undefined; }, context: TContext | undefined) => void

  • This function will fire when the mutation is either successfully fetched or encounters an error and be passed either the data or error
  • If you make multiple requests, onSuccess will fire only after the latest call you've made.

disconnectAsync

(variables: { connector?: Connector | undefined; }, { onSuccess, onSettled, onError }) => Promise<void>

Similar to disconnect but returns a promise which can be awaited.

data

void | undefined

• disconnect return type
• Defaults to undefined
• The last successfully resolved data for the mutation.

error

DisconnectErrorType | null

The error object for the mutation, if an error was encountered.

failureCount

number

• The failure count for the mutation.
• Incremented every time the mutation fails.
• Reset to 0 when the mutation succeeds.

failureReason

DisconnectErrorType | null

• The failure reason for the mutation retry.
• Reset to null when the mutation succeeds.

isError / isIdle / isPending / isSuccess

boolean

Boolean variables derived from status.

isPaused

boolean

• will be true if the mutation has been paused.
• see Network Mode for more information.

reset

() => void

A function to clean the mutation internal state (e.g. it resets the mutation to its initial state).

status

'idle' | 'pending' | 'error' | 'success'

• 'idle' initial status prior to the mutation function executing.
• 'pending' if the mutation is currently executing.
• 'error' if the last mutation attempt resulted in an error.
• 'success' if the last mutation attempt was successful.

submittedAt

number

• The timestamp for when the mutation was submitted.
• Defaults to 0.

variables

{ connector?: Connector | undefined; } | undefined

• The variables object passed to disconnect.
• Defaults to undefined.
