将Firebase作为参数添加到thunk时，Object(...)不是函数 [英] Object(...) is not a function when adding firebase as argument to a thunk

问题描述

使用redux配置Firebase对我来说是一个痛苦.

It's being a pain to me to configure firebase with redux.

我不知道出了什么问题，但我感到很困惑.我正在尝试将 getFirebase 和 getFirestore 作为参数传递给 thunk ，但出现此错误:

I don't know what's wrong but I feel so stuck. I'm trying to pass getFirebase and getFirestore as arguments to the thunk but I'm having this error:

在尝试将其他参数添加到thunk之前，我已经开始工作了.我正在使用以下代码:

I got it working before trying to add the extra argument to the thunk. I'm using the code below:

import { createStore, applyMiddleware, compose } from 'redux'
import thunk from 'redux-thunk'
import { composeWithDevTools } from 'redux-devtools-extension'
import rootReducer from './modules'
import {reduxFirestore, getFirestore} from 'redux-firestore'
import {reactReduxFirebase, getFirebase} from 'react-redux-firebase'
import fbConfig from './firebase/config'

export function initializeStore(initialState) {
  const _thunk = thunk.withExtraArgument({ getFirebase, getFirestore })

  const middlewareEnhancer = applyMiddleware(_thunk)

  const composedEnhancers = compose(
    middlewareEnhancer,
    reduxFirestore(fbConfig),
    reactReduxFirebase(fbConfig)
  )

  const store = createStore(rootReducer, initialState, composedEnhancers)

  return store
}

您对可能发生的事情有任何想法吗?我很绝望.

Do you have any idea of what could be happening? I'm desperate.

非常感谢您.

推荐答案

如果您提到'redux-firestore'和'react-redux-firebase'的版本，那就太好了.

It would be great if you mention the version of 'redux-firestore' and 'react-redux-firebase'.

react-redux v6最近进行了迁移: http://react-redux-firebase.com/docs/v3-migration-guide.html

There is a recent migration for react-redux v6: http://react-redux-firebase.com/docs/v3-migration-guide.html

您可能需要在代码中进行的更改:

The changes you might need to do in your code:

- import { reactReduxFirebase, getFirebase } from 'react-redux-firebase'
+ import { ReactReduxFirebaseProvider, getFirebase } from 'react-redux-firebase'

- import { reduxFirestore, getFirestore } from 'redux-firestore'
+ import { createFirestoreInstance, reduxFirestore, getFirestore } from 'redux-firestore'

+ import firebase from "firebase/app";

当您具有react-redux-firebase的最新版本时，将使用此方法，因为reactReduxFirebase的API已删除.还要如下更改composedEnhancers:

This is used when you have recent version for react-redux-firebase as the API for reactReduxFirebase is removed. Also change the composedEnhancers as below:

- const composedEnhancers = compose(
-    middlewareEnhancer,
-    reduxFirestore(fbConfig),
-    reactReduxFirebase(fbConfig)
-   )

+  const composedEnhancers = compose(
+     middlewareEnhancer,
+     reduxFirestore(firebase, fbConfig)
+  )

添加react-redux-firebase道具

Add the react-redux-firebase props

+ const rrfProps = {
+   firebase,
+   config: fbConfig,
+   dispatch: store.dispatch, 
+   createFirestoreInstance,
+ }

您需要为您的应用提供react-redux-firebase道具:

And you need to provide react-redux-firebase props to your app:

<ReactReduxFirebaseProvider {...rrfProps}>
        <App />
</ReactReduxFirebaseProvider>

它应该可以正常工作.您可以按照上面的链接中所述添加rrfConfig，以防万一它仍然不起作用.

It should work fine. You can add rrfConfig as mentioned in the link given above, in case if it still doesn't works.
