im developing my react native app on MAC and im developing my API from my windows pc.

when im try to reach api from mac with postman i can use

but when i try to send request to api from react-native app (ios or android emulator) it cant reach.

postman request is: Method GET http://192.168.1.109:5000/api/pk/get it returns data on MAC successfully

when i trying to code below:

fetch("http://192.168.1.109:5000/api/pk/get").then(response=>{console.log(response.json())})

it gives NETWORK REQUEST FAILED error.

how can i make this connection on same network two devices (Actually it work on postman. how can i make reach react-native app to other pc API)

The .json() method is asynchronous. You need to add another callback to handle the data from the resolved promise. Change it to this:

fetch("http://192.168.1.109:5000/api/pk/get")
   .then(response => {
    response.json()
        .then(data => console.log(data))
    }

You'll likely also need to enable HTTP for iOS. Add this to your info.plist file

<key>NSAppTransportSecurity</key> 
    <dict>     
        <key>NSAllowsArbitraryLoads</key>     
        <true/> 
    </dict>

See this answer for info on how to do it through XCode.
