Wrap every hook with shared options

Set customOptions to route every generated hook through your own function, so shared behavior like onSuccess or select stays in one place instead of repeated per call. It also emits a HookOptions type, used below to type the wrapper's return value.

kubb.config.ts

import { defineConfig } from 'kubb/config'
import { pluginTs } from '@kubb/plugin-ts'
import { pluginFetch } from '@kubb/plugin-fetch'
import { pluginReactQuery } from '@kubb/plugin-react-query'

export default defineConfig({
  input: './petStore.yaml',
  output: { path: './src/gen', clean: true },
  plugins: [
    pluginTs(),
    pluginFetch(),
    pluginReactQuery({
      output: { path: 'hooks', mode: 'directory' },
      hooks: true,
      customOptions: {
        importPath: './useCustomHookOptions',
        name: 'useCustomHookOptions',
      },
    }),
  ],
})

Output example

Every generated hook calls useCustomHookOptions({ hookName, operationId }) and spreads the result into its query/mutation options. The barrel also re-exports your HookOptions type:

src/gen/hooks/useGetPetById.ts

import { useCustomHookOptions } from './useCustomHookOptions'
import { getPetById } from '../clients/getPetById'
import { queryOptions, useQuery } from '@tanstack/react-query'

export function useGetPetById({ path }, options = {}) {
  const { query: queryConfig = {}, client: config = {} } = options ?? {}
  const { client: queryClient, ...resolvedOptions } = queryConfig
  const resolvedParams = { path: typeof path === 'function' ? path() : path }
  const queryKey = resolvedOptions?.queryKey ?? getPetByIdQueryKey(resolvedParams)
  const customOptions = useCustomHookOptions({ hookName: 'useGetPetById', operationId: 'getPetById' })

  const queryResult = useQuery({
    ...getPetByIdQueryOptions(resolvedParams, config),
    ...customOptions,
    ...resolvedOptions,
    queryKey,
  }, queryClient)

  queryResult.queryKey = queryKey

  return queryResult
}

usage.ts

// ./useCustomHookOptions.ts
import type { HookOptions } from './src/gen'

export function useCustomHookOptions({ hookName, operationId }: { hookName: keyof HookOptions; operationId: string }) {
  if (hookName === 'useGetPetById') {
    return { staleTime: 60_000 } satisfies HookOptions['useGetPetById']
  }
  return {}
