window.__DEV__ is false on debug build on RN version 0.75.4

[sahad00]

Introduction

Earlier I used to detect the env based like this

let isProduction = window.__DEV__ ? false : true;

problem is that isProduction is true on debug build I have generated

build command used

"build:android": "react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res",

I'm unsure about why you're using window..

You should be fine with just:

if (__DEV__) {
    console.log('I am in debug');
}

[sahad00]

@cortinico I tried using the above code but still it gives me false on debug build leading to PRODUCTION = true on debug build based on the below code

let isProduction =__DEV__ ? false : true;

[sahad00]

@cortinico I want to keep this DEV true disabling all developer option for debug build

[cortinico]

You'll have to provide a reproducer using https://github.com/react-native-community/reproducer-react-native as we can't help you further otherwise

[hoxyq]

@sahad00 You mentioned that you are using this command:

"build:android": "react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res",

It specifies --dev false, this is why the value of isProduction is true: you are building an app in production mode.

[cortinico]

It specifies --dev false, this is why the value of isProduction is true: you are building an app in production mode.

True. @sahad00 why are you using a custom bundle command and not the default toolchain?

[sahad00]

@cortinico

  if I manually set this to true then things are good,

@Override
        public boolean getUseDeveloperSupport() {
            return true;
        }

[sahad00]

@cortinico its something like release build on debug configs , we usually have it to be tested

[cortinico]

getUseDeveloperSupport should be configured as such:

https://github.com/react-native-community/template/blob/37144414df684e676b467726915dd225786be414/template/android/app/src/main/java/com/helloworld/MainApplication.kt#L27

[sahad00]

@cortinico

@Override
        public boolean getUseDeveloperSupport() {
            return BuildConfig.DEBUG;
        }

this is not working properly when I install on device but setting it manually to true works
