Sure, here's the code for your "Pokemon App" using Create React App, yarn, Ant Design, List, Redux Toolkit, createSlice, thunk, and axios, merged into a single index.js file: import React, { useEffect } from 'react'; import ReactDOM from 'react-dom'; import { configureStore, createSlice, createAsyncThunk, Provider } from '@reduxjs/toolkit'; import axios from 'axios'; import { List, Avatar, Spin } from 'antd'; import 'antd/dist/antd.css'; const initialState = { pokemonList: [], loading: false, error: null, }; const fetchPokemons = createAsyncThunk('pokemon/fetchPokemons', async () => { const response = await axios.get('https://pokeapi.co/api/v2/pokemon?limit=10'); return response.data.results; }); const pokemonSlice = createSlice({ name: 'pokemon', initialState, reducers: {}, extraReducers: (builder) => { builder .addCase(fetchPokemons.pending, (state) => { state.loading = true; }) .addCase(fetchPokemons.fulfilled, (state, action) => { state.loading = false; state.pokemonList = action.payload; }) .addCase(fetchPokemons.rejected, (state, action) => { state.loading = false; state.error = action.error.message; }); }, }); const store = configureStore({ reducer: { pokemon: pokemonSlice.reducer, }, }); const App = () => { const { pokemonList, loading, error } = store.getState().pokemon; useEffect(() => { store.dispatch(fetchPokemons()); }, []); return ( <div> <h1>Pokemon List</h1> {loading ? ( <Spin size="large" /> ) : error ? ( <p>Error: {error}</p> ) : ( <List itemLayout="horizontal" dataSource={pokemonList} renderItem={(pokemon) => ( <List.Item> <List.Item.Meta avatar={<Avatar src={`https://raw.githubusercontent.com/PokeAPI/sprites/master/sprites/pokemon/${pokemon.url.split('/').slice(-2, -1)}.png`} />} title={<a href="#">{pokemon.name}</a>} /> </List.Item> )} /> )} </div> ); }; ReactDOM.render( <Provider store={store}> <App /> </Provider>, document.getElementById('root') ); Please make sure to set up your Create React App project, install the required packages (yarn add axios @reduxjs/toolkit react-redux antd), and replace the content of your src/index.js file with this code. Don't forget to add your project's styling and other necessary configurations.
