I am currently tasked with developing an application that gives the user various information and details about his network connection using React Native. The main issue is that I am unable to find a library or method to get the user's upload speed or signal strength.
I am using these libraries to get the download speed and network information:
react-native-network-bandwith-speed
#react-native-community/netinfo
These are working just fine.
I found many APIs that allow the integration of fast.com or speedtest.net, but these are not compatible with React Native.
The only thing(s) missing is the upload speed, and signal strength. Any help would be greatly appreciated.

I am creating a React JS PWA web app, so that the users can install it on their mobile devices. Now the client ask to find out a way to push these PWA apps to amazon app store. So my query is whether we have tools for converting the Progressive Web Apps as APK or HTML5 Web app files so that we can put them to amazon app store.
I googled a bit and I am confused, but I am not sure which one is the right one to use and whether we can publish a PWA app to the amazon app store
Any help on this will be very grateful.
Thanks.
PWA needs a browser to be executed. So if you want yo package your pwa as apk(android) you will need to implement a kind of mini-browser with pure android.
Fortunately, this task is very common and there are even online services to do that:
https://appmaker.xyz/pwa-to-apk/
https://pwatoapp.com/
Or if you know java:
https://github.com/xtools-at/Android-PWA-Wrapper
Or c++
https://github.com/RikudouSage/PwaToTwa
Or nodejs
https://github.com/pwa-builder/CloudAPK
You can use the Amazon Web App Tester to verify how your Web app behaves when Published to the Amazon App Store: https://developer.amazon.com/docs/fire-tablets/webapp-app-tester.html
If it performs correctly in the tester, you can then publish the URL directly or upload your files. The full process is described here: https://developer.amazon.com/docs/app-submission/publish-app-webapp-files.html
I would like to create an react native app that can connect to a Hotspot WiFi board and be able to receive and send data for example turn on a light, but I have not been able to find the right package for this.
this board develop by c++
Please help me enter image description here
You should use react-native-wifi-p2p
this is a library to provide WiFi Direct (Peer-To-Peer, P2P) service to react-native.
Important: currently only Android support realized. If you want to provide iOS support, then you should note to react-native-multipeer repository.
I have the following situation:
I have a react web application that is deployed on an NGINX web server via Jenkins. In some cases, my web application does not show up in the browser after I deployed a new version of the application. When you open the web application, it only shows a text: "Loading...".
A quick solution to this problem is to delete your browser data and refresh the web application.
My question: What is the possible cause for this problem or how can I find out what the cause is? I don't want that the users of this application have to delete their browser data when I deploy a new version.
From my experience, It could be because of several reasons:
1) The javascript could be breaking.
2) You might be using some caching strategy that causes the javascript to be cached. Service worker for example.
3) Problem with your react router configuration.
4) A network call might be taking too long to respond.
Need a minimum reproducible example to debug further.
I'm working with React Native and Square Point of Sale. I'm using Web API for Android.
Also I have installed Square Point of Sale.
This is my code:
componentDidMount() {
let url ="intent:#Intent;action=com.squareup.pos.action.CHARGE;package=com.squareup;S.browser_fallback_url=https://my.website.com/index.html;S.com.squareup.pos.WEB_CALLBACK_URI=https://my.website.com/index.html;S.com.squareup.pos.CLIENT_ID=sq0ids-yOurCLieNtId;S.com.squareup.pos.API_VERSION=v2.0;i.com.squareup.pos.TOTAL_AMOUNT=100;S.com.squareup.pos.CURRENCY_CODE=USD;S.com.squareup.pos.TENDER_TYPES=com.squareup.pos.TENDER_CARD,com.squareup.pos.TENDER_CARD_ON_FILE,com.squareup.pos.TENDER_CASH,com.squareup.pos.TENDER_OTHER;end";
Linking.openURL(url).catch(err => console.error("An error occurred", err));
}
This is my error message:
Could not open URL 'intent:#Intent; ... end': No Activity found to handle Intent { act=android.intent.action.VIEW dat=intent: flg=0x10000000 }
What I'm doing wrong?
I tried building using the web API but found that the flow wasn't great. The user doesn't always make it back to the app; sometimes they get stuck on the website.
I built react-native-square-pos to make things easier for the next developer. It uses Native Modules to communicate with the Android / iOS Square PoS APIs.. so you don't have to write Java or Objective-C.
The intent:#Intent that you're using there isn't really going to work from within React Native, since that is used for going from a web browser on an Android device into the Square POS app.
The Android Web API intent is intended to do a hand-off from your browser to the Square POS application, not from application to application.
It sounds like what you'd be wanting to do is use the Square Point of Sale SDK for Android with your React Native application. You'll want to take a look at https://facebook.github.io/react-native/docs/native-modules-android.html about how to link a native module with your React Native application.
I am new to react-native world. Following few tutorials, I found that it react-native app runs on javascript engine on mobile. I am following ios tutorial. So when I go to localhost:8081/index.ios.bundle it loads JS for the app. I know I can use ngrok to manipulate this URL.
I have multiple concerns with this:-
If I change the URL of js from something local to something remote, this would result in a completely new app and now I don't need to go through the App Store to upgrade my app version. Can this be a potential issue in the future?
Since anybody can open this JS in a browser which might have important information like client id and secret for the app, can this be an issue as well?
I am not 100% sure. You can indeed update hybrid app easier and if it is only a quick fix you don't need to go through apple store verification process. Apple can also delete your app and ban you if you don't follow guidelines. Usually your js is local in production for instant app start time, and the network is used only for fresh data.
This is solved with an authentication mechanism.
