Setting up a Slice with RTK

votingPollSlice.js

import { createSlice } from '@reduxjs/toolkit';

// Make an initial state for Redux
const initialVotingPollSlice = {
    votedPollIds: [],
    canVote: false,
    currentVote: null
};

// Create a slice using RTK
export const votingPollSlice = createSlice({
    name: 'polls',
    initialState: initialVotingPollSlice,
    reducers: {
        setCanVote: (state, action) => {
            state.canVote = action.payload;   
        },
        setCurrentVote: (state, action) => {
            state.currentVote = action.payload;
        },
        addVotedPollId: (state, action) => {
            state.votedPollIds.append(action.payload);
        }
    }
});

// Create the action functions, which are generated by `createSlice` using the
// reducer functions you define up above.
export const { setCanVote, setCurrentVote, addVotedPollId } = votingPollSlice.actions;

// Make sure to export your reducer!
export default votingPollSlice.reducer;
