自定义 createApi

目前，RTK Query 包含两个 createApi 变体

• createBaseApi，它只包含与 UI 无关的 Redux 逻辑（核心模块）
• createApi，它包含核心模块和 React Hooks 模块

您可以通过为模块指定非默认选项或添加自己的模块来创建自己的 createApi 版本。

自定义 React-Redux Hooks

如果您希望钩子使用不同版本的useSelector、useDispatch 和 useStore（例如，如果您使用自定义上下文），您可以在模块创建时传入这些钩子。

TypeScript

import * as React from 'react'
import {
  createDispatchHook,
  createSelectorHook,
  createStoreHook,
  ReactReduxContextValue,
} from 'react-redux'
import {
  buildCreateApi,
  coreModule,
  reactHooksModule,
} from '@reduxjs/toolkit/query/react'

const MyContext = React.createContext<ReactReduxContextValue | null>(null)
const customCreateApi = buildCreateApi(
  coreModule(),
  reactHooksModule({
    hooks: {
      useDispatch: createDispatchHook(MyContext),
      useSelector: createSelectorHook(MyContext),
      useStore: createStoreHook(MyContext),
    },
  })
)

JavaScript

import * as React from 'react'
import {
  createDispatchHook,
  createSelectorHook,
  createStoreHook,
} from 'react-redux'
import {
  buildCreateApi,
  coreModule,
  reactHooksModule,
} from '@reduxjs/toolkit/query/react'

const MyContext = React.createContext(null)
const customCreateApi = buildCreateApi(
  coreModule(),
  reactHooksModule({
    hooks: {
      useDispatch: createDispatchHook(MyContext),
      useSelector: createSelectorHook(MyContext),
      useStore: createStoreHook(MyContext),
    },
  })
)

为 RTKQ 自定义 createSelector

coreModule 和 reactHooksModule 都接受一个 createSelector 选项，该选项应该是一个来自 Reselect 的选择器创建器实例，或者具有等效签名。

TypeScript

import * as React from 'react'
import { createSelectorCreator, lruMemoize } from '@reduxjs/toolkit'
import {
  buildCreateApi,
  coreModule,
  reactHooksModule,
} from '@reduxjs/toolkit/query/react'

const createLruSelector = createSelectorCreator(lruMemoize)

const customCreateApi = buildCreateApi(
  coreModule({ createSelector: createLruSelector }),
  reactHooksModule({ createSelector: createLruSelector })
)

JavaScript

import { createSelectorCreator, lruMemoize } from '@reduxjs/toolkit'
import {
  buildCreateApi,
  coreModule,
  reactHooksModule,
} from '@reduxjs/toolkit/query/react'

const createLruSelector = createSelectorCreator(lruMemoize)

const customCreateApi = buildCreateApi(
  coreModule({ createSelector: createLruSelector }),
  reactHooksModule({ createSelector: createLruSelector })
)

创建您自己的模块

如果您想创建自己的模块，您应该查看 react-hooks 模块 以了解实现方式。

这是一个非常简化的版本

import { CoreModule } from '@internal/core/module'
import {
  BaseQueryFn,
  EndpointDefinitions,
  Api,
  Module,
  buildCreateApi,
  coreModule,
} from '@reduxjs/toolkit/query'

export const customModuleName = Symbol()
export type CustomModule = typeof customModuleName

declare module '../apiTypes' {
  export interface ApiModules<
    BaseQuery extends BaseQueryFn,
    Definitions extends EndpointDefinitions,
    ReducerPath extends string,
    TagTypes extends string,
  > {
    [customModuleName]: {
      endpoints: {
        [K in keyof Definitions]: {
          myEndpointProperty: string
        }
      }
    }
  }
}

export const myModule = (): Module<CustomModule> => ({
  name: customModuleName,
  init(api, options, context) {
    // initialize stuff here if you need to

    return {
      injectEndpoint(endpoint, definition) {
        const anyApi = api as any as Api<
          any,
          Record<string, any>,
          string,
          string,
          CustomModule | CoreModule
        >
        anyApi.endpoints[endpoint].myEndpointProperty = 'test'
      },
    }
  },
})

export const myCreateApi = buildCreateApi(coreModule(), myModule())
