Sending multipart Form in ReactJS vs Postman

I've created a registration api that works fine using postman, I added some values there plus image an everything stores correctly, data an image, Later I started my React form and only text works, image is not currently sent to the api I guess.
Doing console.log() api in Node:
console.log(req.files);
with React Form: []
with Postman: an array of object that perfectly works
req.files output using postman
{
fieldname: 'images',
originalname: 'Screen Shot 2021-02-22 at 17.18.41.png',
encoding: '7bit',
mimetype: 'image/png',
destination: 'uploads/',
filename: '091f77f82fb805b1ede9f23205cc578e',
path: 'uploads/091f77f82fb805b1ede9f23205cc578e',
size: 37052
}
Here's my react classes:
httpService.js
import axios from "axios";
import { toast } from "react-toastify";
axios.interceptors.response.use(null, (error) => {
const expectedError =
error.response &&
error.response.status >= 400 &&
error.response.status < 500;

console.log("Loggind the error: ", error);
toast("An unexpected error ocurred.");
}
return Promise.reject(error);
});

How to Load AsyncStorage Data on App Load and set to context in Expo?

I created an Expo project and I am setting some data to LocalStorage using AsyncStorage.
I want to reload that data on App start and want to assign that data to context/State.
How I can achieve that any one can help me to solve this problem.
here is my code of app.js
import React from 'react';
import { Asset } from 'expo-asset';
import * as Font from 'expo-font';
import { AppLoading } from 'expo';
....
const client = new ApolloClient({
// link: new HttpLink({
uri:'',
request: (operation) => {
getToken().then(token=>{
console.log('APIToken:', token);
operation.setContext({
headers: {
'api-token': token ? `${token}` : ''
}
})
});
},
//}),
cache: new InMemoryCache(),
});
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fffef9',
},
});
export default class App extends React.Component {
constructor(props) {
super(props);
this.updateContext=(key, value)=>{
this.setState({
[key]: value
});
};
this.updateStack=(stack)=>{
this.setState({
activeStack: stack
});
};
this.loadUsers=(users, _activeUser)=>{
console.log('Users:', users);
this.setState({
users: users,
activeUser: _activeUser
});
};
this.logOutUser=()=>{
this.setState({
activeUser: {},
users:[],
activeStack:'Auth'
});
};
this.state = {
isReady: false,
activeUser:{},
users: [],
activeStack:'Auth',
updateStack: this.updateStack,
updateContext: this.updateContext,
loadUsers: this.loadUsers,
logOutUser: this.logOutUser
};
}
render() {
if (!this.state.isReady) {
return (
<AppLoading
startAsync={this._cacheResourcesAsync}
onFinish={(res) => {this.setState({ isReady: true })}}
onError={console.warn}
/>
); }
return (
<ApolloProvider client={client}>
<SafeAreaProvider>
<SafeAreaView forceInset={{ bottom: 115 }} style={styles.container}>
{Platform.OS === 'ios' && <StatusBar barStyle="default" />}
<AppContext.Provider value={this.state}>
<AppNavigator/>
</AppContext.Provider>
</SafeAreaView>
</SafeAreaProvider>
</ApolloProvider>
);
}
async _cacheResourcesAsync() {
await Promise.all([
Asset.loadAsync([
// require('./assets/images/robot-dev.png'),
]),
Font.loadAsync({
'body': require('./assets/fonts/Archivo-Regular.ttf'),
'body-bold': require('./assets/fonts/Archivo-SemiBold.ttf'),
'headline': require('./assets/fonts/Nunito-Medium.ttf'),
'headline-bold': require('./assets/fonts/Nunito-Bold.ttf'),
'headline-extra-bold': require('./assets/fonts/Nunito-ExtraBold.ttf'),
})
]);
}
}
I have a function to loaduser() in a separate file, where i am loading users from localstorage and returning a promise. You can tell me where i should call loadUser() and handle its promise to loadState.
Thanks

I had the same problem. My solution was create another Component.
My App.js:
export default () => {
const [isReady, setIsReady] = useState(false);
const loadAssetsAsync = async () => {
const imageAssets = cacheImages([
require('./assets/images/bg_screen1.jpg'),
require('./assets/images/bg_screen2.jpg'),
require('./assets/images/bg_screen3.jpg'),
require('./assets/images/bg_screen4.jpg'),
require('./assets/images/user-cool.png'),
require('./assets/images/user-hp.png'),
require('./assets/images/user-student.png'),
require('./assets/images/avatar1.jpg'),
]);
const fontAssets = cacheFonts([
...vectorFonts,
{ georgia: require('./assets/fonts/Georgia.ttf') },
{ regular: require('./assets/fonts/Montserrat-Regular.ttf') },
{ light: require('./assets/fonts/Montserrat-Light.ttf') },
{ bold: require('./assets/fonts/Montserrat-Bold.ttf') },
{ UbuntuLight: require('./assets/fonts/Ubuntu-Light.ttf') },
{ UbuntuBold: require('./assets/fonts/Ubuntu-Bold.ttf') },
{ UbuntuLightItalic: require('./assets/fonts/Ubuntu-Light-Italic.ttf') },
]);
await Promise.all([...imageAssets, ...fontAssets]);
};
if (!isReady) {
return (
<AppLoading
startAsync={loadAssetsAsync}
onFinish={() => setIsReady(true)}
onError={console.warn}
/>
);
}
return <RootNavigator />;
};
My RootNavigator:
export default () => {
const [loaded, setLoaded] = useState(false);
const [init, setInit] = useState(false);
useEffect(() => {
const fetchData = async () => {
const type = await getUserType()
const name = await getName()
const UID = await getUID()
const token = await getToken()
if (!type || !name || !UID || !token) {
inital = 'Login'
} else if (type === 'CLIENT') {
inital = 'Client'
} else if (type === 'EMPLOYEEE') {
inital = 'Employee'
}
setInit(inital)
}
fetchData()
}, [])
function returnRoute() {
AppNavigator = createStackNavigator({
Login: {
screen: LoginScreen,
navigationOptions: {
headerShown: false
}
},
Client: {
screen: DrawerNavigator,
navigationOptions: {
headerShown: false,
},
},
StoreBooking: StoreBookingScreen,
StoreContract: StoreContractScreen,
IndexContracts: IndexContractsScreen,
ShowActivity: ShowActivityScreen,
ShowUniqueBooking: ShowUniqueBookingScreen,
Addresses: ShowAddressesScreen,
},
{
initialRouteName: init,
defaultNavigationOptions: {
headerStyle: {
backgroundColor: cli.Client.b1,
},
headerTintColor: '#fff',
headerTitleStyle: {
fontWeight: 'bold',
},
}
})
RootNavigator = createAppContainer(AppNavigator);
return <RootNavigator />
}
return (
loaded && init ? (
<Awaiter />
)
:
returnRoute()
)
}

How to show props from reducers in component

I have a problem when want to show
const mapStateToProps = state => {
return {
loading: state.auth.loading,
error: state.auth.error,
userId: state.auth.userId,
tokenId: state.auth.token
}
}
this in my function
register = (event) => {
event.preventDefault()
this.props.onAuth( this.state.email, this.state.password, this.state.isSignup );
localStorage.setItem('token', this.props.tokenId);
localStorage.setItem('userId', this.props.userId);
}
I see token and userId after the second click. But I can't see after the first click. What I need more to show immediately?
This is my auth.js reducers
import * as actionTypes from '../actions/actionsTypes';
import { updateObject } from '../utility';
const initialState = {
token: null,
userId: null,
error: null,
loading: false
};
const authStart = ( state, action ) => {
return updateObject( state, { error: null, loading: true } );
};
const authSuccess = (state, action) => {
return updateObject( state, {
token: action.idToken,
userId: action.userId,
error: null,
loading: false
} );
};
const authFail = (state, action) => {
return updateObject( state, {
error: action.error,
loading: false
});
}
const reducer = ( state = initialState, action ) => {
switch ( action.type ) {
case actionTypes.AUTH_START: return authStart(state, action);
case actionTypes.AUTH_SUCCESS: return authSuccess(state, action);
case actionTypes.AUTH_FAIL: return authFail(state, action);
default:
return state;
}
};
export default reducer;
But, after the first click, I got token in my render function.
{this.props.tokenId}
Could you please help me? I think I need to use async/await. But I am not sure.
Here you go Header.js

switchAuthModeHandler = (event) => {
event.preventDefault()
this.setState(prevState => {
return {
isSignup: !prevState.isSignup
}
})
}
register = (event) => {
event.preventDefault()
this.props.onAuth( this.state.email, this.state.password, this.state.isSignup );
localStorage.setItem('token', this.props.tokenId);
localStorage.setItem('userId', this.props.userId);
}
render() {
let regBtn = ''
if (this.state.isSignup) {
regBtn = 'Register'

let login = null
if(!this.props.tokenId) {

const mapDispatchToProps = dispatch => {

};
export const auth = (email, password, isSignup) => {
return dispatch => {
dispatch(authStart());
const authData = {
email: email,
password: password,
fullName: 'Boris Civcic',
role: 'admin',
returnSecureToken: true
};
let url = 'https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=AIzaSyC5nW8-XOJADEvU7Mi7sgmhUNhHfRxXNQI';
if (!isSignup) {
url = 'https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyC5nW8-XOJADEvU7Mi7sgmhUNhHfRxXNQI';
}
axios.post(url, authData)
.then(response => {
console.log(response);
dispatch(authSuccess(response.data.idToken, response.data.localId));
// dispatch(checkAuthTime(response.data.expiresIn));
})
.catch(err => {
dispatch(authFail(err.response.data.error));
})
};
};
this is auth.js action
and this is utility
export const updateObject = (oldObject, updatedProperties) => {
return {
...oldObject,
...updatedProperties
};
};

In your register handler, onAuth is an asynchronous action but you've populated localStorage immediately. You should wait onAuth returns and then set your localStorage items.
first return a promise from your thunk ( simply by adding return before axios ):
...
return axios.post(url, authData)
.then(response => {
console.log(response);
dispatch(authSuccess(response.data.idToken, response.data.localId));
// dispatch(checkAuthTime(response.data.expiresIn));
})
.catch(err => {
dispatch(authFail(err.response.data.error));
})
...
Then set your localStorage items like this:
register = (event) => {
event.preventDefault();
this.props.onAuth( this.state.email, this.state.password, this.state.isSignup )
.then(() => {
localStorage.setItem('token', this.props.tokenId);
localStorage.setItem('userId', this.props.userId);
});
}

The task_details triggers the construction:
<div className="container">
<div><h2>Not found</h2></div>

There is an error in the console:
