Visual Studio Code debugging

I have an issue with Realm and VSCode debugging, i’m unable to debug because apparently the Realm constructor is missing.

[vscode-react-native] Finished executing: react-native run-ios --simulator iPhone 6s --project-path ios
node --debug-brk=35498 launchReactNative.js 9090 
Debugger listening on [::]:35498
[vscode-react-native] Downloaded debuggerWorker.js (Logic to run the React Native app) from the Packager.
[vscode-react-native] Starting debugger app worker.
[vscode-react-native] Established a connection with the Proxy (Packager) to the React Native application
[vscode-react-native] Debugging session started successfully.
Missing Realm constructor - please ensure RealmReact framework is included!
Module AppRegistry is not a registered callable module.

Then, if I Stop Remote JS Debugging, it works.

However, everything works fine in remote js debugging or not when I use run-android or run-ios instead of VSCode.

So, I guess it’s not an integration issue and something went wrong between Realm and VSCode debugging.

Environment

osx@10.11.6 node@6.2.2 npm@3.9.5 react-native@0.32.0 realm@0.14.3 vscode-react-native@0.1.6 vscode@1.4.0

Related to #374, #562 et #571.

I believe that the work to support VSCode’s debugger has already been done in the past, the only part that needs to change is the conditional that throws the missing constructor error. Right now it checks for window != null which works in chrome but fails in VSCode. You could modify the check to window != null || __debug__ !== null and that should cause it to work with us.

Hey @charpeni,

Visual Studio Code uses a worker to execute a React Native app’s JavaScript code inside the editor process when debugging, sort of how like Chrome debugging but unfortunately distinct enough that we’ll need to figure out how we can wire up the Visual Studio Code worker to the Realm binary on the device.

I’m adding this to the backlog so we can get more research done and (hopefully) support VS Code’s sandbox debugger.
