Rematch for Redux: Setting State to that of the Payload when Signing Up - firebase

Question

How do I set state to that of my payload? I would like my global state to have the recent changes, not the payload. Please could someone explain why/how this is happening? Do I need to create another reducer/effect to set the state? I want to set this state as global within the app. I would greatly appreciate it.
I am using the following:
Firebase Firestore
Rematch for Redux
React Native
This is My debugger (image).
Result of the code below.
Here is my code:
Index.js
import { init } from '#rematch/core'
import user from './user'
const models = {
user,
}
const store = init({
models,
})
export default { getState, dispatch } = store
Model.js (User.js)
import firebase from 'firebase';
import db from '../config/firebase'
const user = {
state: {},
reducers: {
login(userData) {
return userData
},
email(state, email) {
return { ...state, email }
},
password(state, password) {
return { ...state, password }
},
username(state, username) {
return { ...state, username }
},
fullname(state, fullname) {
return { ...state, fullname }
},
},
effects: () => ({
async signup() {
const { email, password, username, fullname } = getState().user
const response = await firebase.auth().createUserWithEmailAndPassword(email, password)
if (response.user.uid) {
const userData = {
uid: response.user.uid,
email: email,
username: username,
fullname: fullname,
bio: 'test',
gender: 'teste',
phoneNum: 'teste',
profilePic: 'te',
status: 'teste',
}
db.collection('users').doc(response.user.uid).set(userData)
alert(userData.uid)
return dispatch.user.login(userData)
}
}
})
}
export default user

Answer 1

The problem is that you are returning the current state again in the login reducer. (you declared is at user data)
login(state, payload) {
return {
...state,
...payload
}
// this will take the global state and overwrite everything that is in payload (merge both objects
},
else you could just do just return payload but this could overwrite other stored values in the future!
