The value for the user changes, what's wrong?

Question

redux

action:

export const login = () => {
    return {
        type: 'LOGIN'
    }
}

reducer:

const user = (state = false, action) => {
    switch(action.type) {
        case 'LOGIN':
            return !state;
        default:
            return state;
    }
}

export default user;

all reducers:

import { combineReducers } from 'redux';
import user from './user.js';

const allReducers = combineReducers({
    user
})

export default allReducers;

so I change the user value totrue
onSubmit={() => dispatch(login())}

<form onSubmit={() => dispatch(login())} className="auth__content-form" action="/auth/login" method="POST">
    <input type="email" placeholder="Электронная почта" name="email" required />
    <input type="password" placeholder="Пароль" name="password" required />
    <input type="submit" value="Войти" />
</form>

After that, the user's state changes, but after a reboot it becomesfalse

Answer 1

Well, cancel the reboot. In the onSubmit event, accept the event argument and call event.preventDefault()
