I am learning React Native and would like to know why
React Native's serializable communication makes it possible to use Chrome's debugger. Why is that?
I'm assuming your question is phrased this way due to this sentence from React Native's homepage:
The communication is also fully serializable, which allows us to leverage Chrome Developer Tools to debug the JavaScript while running the complete app, either in the simulator or on a physical device.
To understand that, you have to know a little bit more about how React Native works. The "communication" discussed here is the communication between your UI layer, and the JS processing layer. In React Native, this UI layer is the native elements of your iOS or Android app.
The conversations between the two are fully serializable, which means they're able to be converted into a stream of bytes (serialized), sent over the communication channel, and then regenerated (deserialized) on the other end.
The Chrome based React Native debugging tools proxy between the communication of the UI layer and the JS processing layer. It's possible to use the tools to do this because they can just play the same deserialization/serialization game the communication method can play but parse the contents of the message and show it to you first.

I wish to implement a sip call using sip library on React native to have one code that can be used for both android as well as iOS device. I have never worked in javascript framework and wish to know which library are used to implement it and how feasible it is for any production purpose.
New to react Native. Just like we can see all the API calls and the headers, as well as the request & response parameters, passed to the APIs from the network tab from the browsers, similarly, is there any way we can see the same while developing mobile applications in react native?
You could use Flipper if you use React-Native v0.62+. Flipper has a very neat network inspector and It has also plenty of debugging utilities.
Use the Network inspector to inspect outgoing network traffic in your apps. You can easily browse all requests being made and their responses. The plugin also supports gzipped responses.
According to Flipper's official documentation.
Here is an example screenshot from the Flipper Network tab:
There are some other network inspectors but I highly recommend using Flipper.
I want to know how to make a network request on app initialization from the native modules instead of doing it in Javacsript/React Native code.
I saw in a video that one way to speed up the initialization time is to move the network requests to the native-modules (iOS/Android), that way when the app is ready the response of the network request is given to React-Native to handle it.
The video is titled "Performance in React Native" by Ram Narasimhan. There is no example provided.
Here's an example I made for both iOS and Android: https://github.com/corinaferencz/network-native-module
Network requests are handled in native, and the response is sent to React Native.
Can you please help with this.
I am trying to develop mobile and web apps using react native with single code base for web, android and ios. Can we Develop Web and Mobile Application with single code base by using React Native?
The simple answer is yes. However, there are a lot of caveats that you could encounter along the road with certain device requirements and functionality where you may have to write conditional code, but it could still stay in the same codebase.
The easiest way to get started is by using Expo (https://expo.io), which would let you get started with a project that could be run on Android, iOS, and the Web (via React Native Web) all with very minimal setup on your part.
Is it possible to integrate React-Native with Webhooks?
Currently, I have a chatbot using React, Dialogflow and webhooks. I am intending to port over to React-Native. Hence, I like to find out if possible to use webhooks to integrate React-Native with Dialogflow?
When I google, I find tons of materials regarding React with Webhooks but none concerning React-Native with Webhooks.
In case not possible to integrate React-Native with Webhooks, how does one work around it then?
Thanks :)
Webhooks usually mean that a URL is called which triggers some kind of action on your server. In the client world you would use sockets.
So if you wish to communicate from server to client instead of vice versa you should either use sockets or native notifications, at least for iOS.
The app is only alive for a certain amount of time when not being used and then its terminated by OS on Apple products. Your socket will thus be shut down. Apple recommends to use native notifications to wake you app up in such cases.
This works espacially well for chat or voip apps.
There are a bunch of frameworks for handling push notifs here is a good tutorial: https://medium.com/ios-expert-series-or-interview-series/voip-push-notifications-using-ios-pushkit-5bc4a8f4d587
