Linh Nguyễn I'm really thank you!i have done it successfully.

I don't know what instructions I should follow. you have handled the axios upload function, the api parameters you don't use. reducers: { setUploadProgress: (state, action) => { return { ...state, uploadProgress: action.payload } } }, setUploadProgress in here. what for?And again, in here? const [uploadProgress, setUploadProgress] = useState(0); I'm confused

kintu denis in progressbar component, we will pass value= res.data. is it right?

api.dispatch(setUploadProgress ) . where is setUploadProgress from?

Hello sir! I really need it. But it's so hard to understand. Can you have source code for illustration
