calling for fetchUser.js
import firebase from "firebase";
import {USER_STATE_CHANGE} from '../constants/index'
export function fetchUser() {
return( async(dispatch)=>{
console.log('dssd')
firebase.firestore()
.collection("users")
.doc(firebase.auth().currentUser.uid)
.get()
.then(
(snapshot)=>{
if(snapshot.exists){
dispatch({type: USER_STATE_CHANGE , currentUser : snapshot.data()})
}
else{
console.log('error_fitchUser')
}});
})
}
user.js
import {USER_STATE_CHANGE} from '../constants/index'
const initialState={
currentUse:null,
}
export const user=(state=initialState,action)=>{
switch (action.type) {
case USER_STATE_CHANGE:
return{
...state,
currentUser:action.currentUser,
}
default:
return({})
}
}
the problem is that I don't Know how to send dispatch when calling for fetchUser .........................................................................................................
Presumably you've already added your asynchronous action middleware to your store. You can use the useDispatch react-redux hook and wrap your calls to your fetchData and fetchUser action creators with a call to dispatch. The middleware will handle passing dispatch to the asynchronous action.
const dispatch = useDispatch();
useLayoutEffect(() => {
dispatch(fetchData());
dispatch(fetchUser());
}, []);
