Part 1: Create a Post ... Redux createStore issue!

[AAdewunmi]

Hi, Form isnt sending post data (creator: '', title: '', message: '', tags: '', selectedFile: '') to mongodb. From console log, I can see the post request being fulfilled but the array is empty and mongodb hasn't received the post data. I've got my /3000 & /5000 servers running without error and mongodb cluster is running. Any suggestions for a fix? Thanks.

/api/index.js

import axios from 'axios';

const url = 'http://localhost:5000/posts';

export const fetchPosts = () => axios.get(url);
export const createPost = (newPost) => axios.post(url, newPost);

/actions/posts.js

import * as api from '../api';

export const getPosts = () => async (dispatch) => {
  try {
    const { data } = await api.fetchPosts();
    dispatch({ type: 'FETCH_ALL', payload: data });
  } catch (error) {
    console.log(error.message);
  }
};

export const createPost = (post) => async (dispatch) => {
  try {
    const { data } = await api.createPost(post);
    dispatch({type: 'CREATE', payload: data});
  } catch (error) {
    console.log(error.message)
  }
};

Can I try to solve this bug?

Yes you can ...

Issue fixed! If you are having issues with Redux createStore() being depreciated, here's how to use configureStore():

1. Run on server side console ->

   NPM

   npm install @reduxjs/toolkit

   Yarn

   yarn add @reduxjs/toolkit

2. Include configureStore() in your client/src/index.js file

import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
// import { createStore, applyMiddleware, compose} from "redux";
// import thunk from "redux-thunk";
import { configureStore } from "@reduxjs/toolkit";
import reducers from "./reducers";
import App from "./App";
import "./index.css";

// const store = createStore(reducers, compose(applyMiddleware(thunk)));
const store = configureStore({ reducer: reducers });
ReactDOM.render(
    <Provider store={store}>
       <App />
    </Provider>,
  document.getElementById("root")
);

Job done!
