I am building a React Native application and I need to save some sensitive data like a token and a refresh token. The obvious solution is to save that information using AsyncStorage. The problem is the security level of the AsyncStorage.

AsyncStorage provides a way to locally store tokens and data. It can be, in some ways, compared to a LocalStorage option. In full production applications, it is recommended to not access AsyncStorage directly, but instead, to use an abstraction layer, as AsyncStorage is shared with other apps using the same browser, and thus an ill-conceieved removal of all items from storage could impair the functioning of neighboring apps.

https://auth0.com/blog/adding-authentication-to-react-native-using-jwt/

In a native app, I would go for Keychain in iOS and Shared Preferences in private mode in Android.

For what I read in the documentation provided by React Native:

On iOS, AsyncStorage is backed by native code that stores small values in a serialized dictionary and larger values in separate files. On Android, AsyncStorage will use either RocksDB or SQLite based on what is available.

https://facebook.github.io/react-native/docs/asyncstorage.html

They never talk about the security of that data.

It is the best solution create a module for Android (that uses Shared Preferences in private mode) and another for iOS (that uses Keychain) to save the sensible data? Or it is safe to use the AsyncStorage methods provided?

I am working on chat app using react-native in iOS. I want to do badge increment for every notification. When app is inactive, Is it possible to call AppDelegate UIApplication from the notification service extension?

Is there a way to set fontStyle: 'italic'only for the placeholder of the TextInput in React Native?

looking here at the documentation seems like you can only set a placeholder and placeholderTextColor.

In my scenario, I am trying to create global class for android back button handler and reuse it in multiple screen class files. How to do it? I tried below code but I dont know how to access common class from other classes.

My Code Below (Androidhandler.tsx)

export default class hardware extends Component {  constructor(props) {    super(props);    this.BackButton = this.BackButton.bind(this);  }  componentWillMount() {    BackHandler.addEventListener'BackPress',this.BackButton);  }  componentWillUnmount() {    BackHandler.removeEventListener('BackPress',this.BackButton);  }  BackButton() {    if(this.props.navigation){        this.props.navigation.goBack(null);        return true;      }    }}

I use react native version 0.60.3. Before one year make an application with local images and it works well. I update Xcode to version 11 and old code and images work well also. I try to add new images for dark mode but the image doesn't show, there isn't an error, only blank space. In code use images from js file like :"url":require("../images/page1.png").

Images are added to copy bundle resources.

I try with command :npx react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios

and copy assets and main.jsbundle to Xcode and get the same results, before I don't have assets folder in XCode, images are been in copy bundle resources.Old images work (which are added before one year), new images don't work. Did I miss something? I don't have an error and don't know how to fix this issue.

My code:

<CustomImage         width={getImgWidth} height={getImgHeight}         lightpath={it.url}         darkpath={it.urldark}        darkmode={theme.darkmode} />

CustomImage.js

const CustomImage = (props) => {  return (<View style={{ width: props.width, height: props.height }}>  {props.darkmode ? (<Image      resizeMode="contain"      style={{ width: props.width, height: props.height }}      source={props.darkpath}    />     ) : (<Image      resizeMode="contain"      style={{ width: props.width, height: props.height }}      source={props.lightpath}    />  )}</View> ); };

Am working on this login page where I had to use TouchableOpacity on a this text "Already have an account? Sign in instead!" to send me to the singin screen and for some reason it didn't work so naturally I thought I had an error in my code and after hours of debugging I had the idea to make a simple button with the same functionality and it works for am wondering is there something wrong with TouchableOpacity on expo or there is somekind of logic error i missed.

here is the code i used :

From my signup screen :

return (<View style={styles.container}><NavigationEvents onWillBlur={clearErrorMessage} /><AuthForm        headerText="Sign Up for Tracker"        errorMessage={state.errorMessage}        submitButtonText="Sign Up"        onSubmit={signup}      /><NavLink        routeName="Signin"        text="Already have an account? Sign in instead!"      /></View>  );

from the Navlink component :

return (<><TouchableOpacity onPress={() => navigation.navigate(routeName)}><Spacer><Text style={styles.link}>{text}</Text></Spacer></TouchableOpacity><Button        title="go to sing in"        onPress={() => {          navigation.navigate("Singin");        }}      /></>  );

I want to move and element right to place I click with onPress event.

Example if I click on the screen with position x: 200, y: 300, so my element should move there from position x: -100, y: -100, I tried it, but it is not moving to the exact position I press on the screen. my code:, although it moves, but moves not exactly to the place I want...

const styles = StyleSheet.create({    alertAutoCloseContainer: {        left: 0, top: 0,        margin: 10, marginHorizontal: 40, position: 'absolute',        padding: 10, maxWidth: 500, maxHeight: 400, zIndex: 1000,        backgroundColor: 'rgba(0, 50, 50, 0.8)', borderRadius: 5,    },    alertAutoCloseText: {        color: '#fff', fontFamily: 'IRANSansMobile'    }});const { Value } = Animated;const animatedValue = new Value(0);const MyAlert = memo(forwardRef(({ }, ref) => {    const [state, setState] = useReducer((s, v) => v, {        status: true, xAxis: 0, yAxis: 0, parentData: {            text: ""        }    });    useImperativeHandle(ref, () => {        return ({            startAnimation: ({ xAxis, yAxis, parentData }) => {                const { status } = state;                setState({                    ...state, xAxis, yAxis,                    parentData, status: !status                });                Animated.timing(animatedValue, {                    toValue: status === true ? 1 : 0, duration: 500                }).start();            },            stopAnimation: ({ }) => {                Animated.timing(animatedValue, {                    toValue: 0, duration: 500                }).start();            }        })    });    console.log(state.xAxis, state.yAxis);    return (<Animated.View style={{            ...styles.alertAutoCloseContainer, transform: [                {                    translateY: animatedValue.interpolate({                        inputRange: [0, 1],                        outputRange: [0, state.yAxis],                        extrapolate: 'clamp'                    })                },                {                    translateX: animatedValue.interpolate({                        inputRange: [0, 1],                        outputRange: [0, state.xAxis],                        extrapolate: 'clamp'                    })                },                {                    scale: animatedValue.interpolate({                        inputRange: [0, 1],                        outputRange: [0, 1]                    })                }            ]        }}><Text style={styles.alertAutoCloseText}>                {state.parentData.text}</Text></Animated.View>    );}), (p, n) => true);

While uploading app, I got this from apple,

TMS-90809: Deprecated API Usage - Apple will stop accepting submissions of new apps that use UIWebView APIs starting from April 2020. See https://developer.apple.com/documentation/uikit/uiwebview for more information.

I tried searching for the "UIWebView" in the project search option in vs code but no luck, but there is 'react-native-web' is used in the application.Could this (react-native-web) be the reason for getting a warning?And if some other component is using webView how could I identify it?

Any help would be appreciated.Thank you.

In my scenario, I am trying to change the switch value on real time. Here, whenever the switch index value on/off changing componentWillReceiveProps calling twice at a time. How to solve this issue?

My Code Below

componentWillReceiveProps(nextProps) {    switch (this.state.selectedIndex) {      case 0:        if (nextProps.checkState.reported.on) {          this.setState({ switchValue: true });        } else {          this.setState({ switchValue: false });        }        break;      default:        this.setState({ switchValue: nextProps.checkState.on });    }  }

I created an AuthForm component that I use for a sign up and sign in screen after styling the screen I noticed every time I click on the keyboard to type some input everything changes its original placement and some components overlay others and it turns into a mess, how can I fix this?

Here is the code i used

recently i've found this plugin can preview many device of Android or iOS device in one installed apps,

gif of the plugin is at https://github.com/aloisdeniel/flutter_device_preview

does react native has something like this?

I know there's some similar plugin like Expo and Appetize but i need something like this,

i mean i can preview of many device in my apps, not installing my app on many devices.

I have tried writing the config object for my react native app according to the react-navigation configuring links docs.

I defined a series of path --> route mappings including Chat:'feed' and Explore:'news'

My goal is for the app to default to the Profile screen when resolving https://example.com/someusername and pass 'someusername' as the id param. Similar to how https://instagram.com/apple maps directly to the profile screen for @apple's account.

const linking = {  prefixes: ['https://example.com', 'example://'],  config: {    Home: {      path: '',      screens: {        Chat: 'feed',        Explore: 'news',        Profile: ':id',      },    },  },}

I will not allow users to make accounts @feed, @news, etc. to avoid conflict. I also display "user not found" message if 'someusername' does not exist yet

Is there a correct way to do this config object? Or if I need to write custom getStateFromPath / getPathFromState functions, does anyone have an example?

I've build a React Native App which connects to different smart devices to control lights.I was wondering if there is way to connect my app with alexa echo and sending texts, which alexa speaks? Or even sending commands, which Alexa executes?

Is this possible? I don't find anythin similar on the internet.

Thanks

I would like to post a picture that is encoded in base64 along with a REST API

const data = {        UserId:this.state.user.id,        PictureUri:avatar    };    const res = await fetch(        url,        {            method: "POST",            headers: {"Accept": "application/json","Content-Type": "application/json"            },            body: JSON.stringify(data)        }    )

The problem that I have encountered is that this POST (HTTPS) request doesn't work when I am using the cellular data of the iPhone whereas it works when I am on WiFi or a Mobile Hotspot. In such a case, the server (in DMZ) does not receive any request.

What can block this communication?

I've published a React Native App and released it through TestFlight to some internal users of the company.While on debug and testing before the release we've never had reported crashes, some users started experiencing random crashes on the App (at restart, the App continued as normal).Now, since the app is developed in React Native, the crash log reported from TestFlight doesn't seem to be so useful, at least for me, at tracking down the possible bug.

This is the crash log:

I generated an app via GoNative. I use her and I use the camera.

So, on Android, I just modify the AndroidManifest and add the permission.

On iOS, I try to modify the info.plist, but the camera still not working.

Can someone has a solution ? Thanks.

I am currently developing a react native app integrating it with IPFS technology, I have an requirement to calculate network usage in my app, that is how much data is used while sending and receiving the information from IPFS.

I have searched for plugins, but was only able to get it for Android.

So, what I have thought is to get size of Bytes sent and received from my app and to calculate data usage based on it.. is this a correct approach to get the network usage stats of my app ?

If there is any another way available for both Android & iOS platforms (hopefully plugin as I am not an Native developer) then please suggest.

Thanks.
