Hire+Plus! For Employees Here's how I built it (Redux - Job)

export type JobData = {
    id: string;
    companyName: string;
    position: string;
    location: string;
    salary: string;
    datePosted: string;
    jobType: string;
    applyUrl: string;
    description: string;
};

import { createSlice, createAsyncThunk } from '@reduxjs/toolkit';
import { getJobById, getJobs } from '../../../utils/firebase/firebase.utils';
import { JobData } from './jobTypes';

interface jobState {
    jobs: JobData[];
    isLoading: boolean;
}
const initialState: jobState = {
    jobs: [],
    isLoading: false,
};

export const getPostedJobs = createAsyncThunk('job/getJobs', async () => {
    const jobs = await getJobs();
    return JSON.stringify(jobs);
});
export const getPostedJobById = createAsyncThunk(
    'job/getJobById',
    async (id: string) => {
        const jobs = await getJobById(id);
        const [jobObj] = jobs;
        return JSON.stringify(jobObj);
    }
);

const JobSlice = createSlice({
    name: 'job',
    initialState,
    reducers: {},
    extraReducers: (builder) => {
        builder
            .addCase(getPostedJobs.pending, (state) => {
                state.isLoading = true;
            })
            .addCase(getPostedJobs.fulfilled, (state, action) => {
                state.isLoading = false;
                state.jobs = JSON.parse(action.payload);
            })
            .addCase(getPostedJobs.rejected, (state, action) => {
                state.isLoading = false;
                console.log('error with jobs', action.error);
            })
            .addCase(getPostedJobById.pending, (state) => {
                state.isLoading = true;
            })
            .addCase(getPostedJobById.fulfilled, (state, action) => {
                state.isLoading = false;
                state.jobs = JSON.parse(action.payload);
            })
            .addCase(getPostedJobById.rejected, (state, action) => {
                state.isLoading = false;
                console.log('error with getting job by id', action.error);
            });
    },
});

export default JobSlice.reducer;
