Is there any way to connect to telnet server and send commands via react native ?
I Tried to test this library i facing errors because its have old dependencies and way to fix it ?
Have you read the documentation that the site provided? https://www.npmjs.com/package/telnet-client ,
if you have implemented it already, why not show the error ?

I am working with Expo and i dont want to use dev client. Anyone got any alternative to react-native-fast-image or a way to implement it without using dev client?
I have made a REST API for my react native application and want to fetch data from it, though this is not possible for me.
I have tried using localhost and ipv4 as the url, but it doesn't help at all. I also get an "Network Error" at times when I change to the different URLs, which I don't fully understand why they show up, since ipv4 or localhost should work.
I usually get a warning about the metro server after a while, if that has anything to do with it.
How can I connect my React Native client to my express backend?
try to run this command, it will link the port in you device which you run your React Native app with the port of your laptop,
"adb reverse tcp:3000 tcp:3000"
then run "react-native run-android"
i work with the port 3000, you can work with the port you want
I found the issue! I forgot a / in my base url, which broke the whole thing with axios. And I had one too many in my login post request!
I'm using a React Native app built with expo. I wanted to know how to detect slow internet connection using it.
If you are using expo then you can check the netinfo docs, where type of connection will give an approx of network speed. expo netinfo
If you want to check the network status that suddenly it went down or offline you can use the react-native-offline library as it constantly pings and checks , and its documentation is good . react-native-offline
I'd like to have pure network level verification that an IP is reachable, not the HTTP level, since I am trying to verify connectivity with devices that may not implement HTTP.
I already use react-native-udp, react-native-tcp and other native bindings, but does not seem a method to achieve this goal.
Thanks
If you have not found a package that does it, I would go with a native solution. There are several packages for iOS, like GBPing or Apple SimplePing and a quick search in Google showed some pointers on how to implement it for Android. Then you just have to do the binding to JS, for which you can find some help on the documentation.
You can use react-native-ping package to perform ICMP ping on react-native.
To install package:
npm i react-native-ping
Have anyone successfully used socket.io-client with react-native-android? I did some searching but it seems to be a mix bag.
I'm trying to figure out if I should use it for my project and I don't have the android version setup yet. So I want to see if it actually works before I jump the gun.
I have https://github.com/gcrabtree/react-native-socketio successfully working on android with React-Native 0.39. There does however appear to be an issue with the socketConfig parameters not being parsed correctly when compiled but you can get around this by adding the parameters to the socket connect url (obviously not all paramaters can be passed into the connection url). My code for connecting to a room that has token authentication
this.socket = new SocketIO(`${this.baseUrl}/${this.socketRoom}?token=${GlobalState.socketToken}`);
this.socket.on('connect', () => resolve());
this.socket.connect();
I am yet to get this working on iOS though.
