Ionic VS Code Extension: breakpoints not being set for @ionic/angular app w/ capacitor

Hello everyone,

I’ve created an Ionic application using the following command:

ionic start test3 blank --type=angular --capacitor

Now I’m trying to use the Ionic VS Code extension to debug it on an Android device. What I’m doing is first clicking Run > Android , then Debug > io.ionic.starter , but I’m encountering issues with my breakpoints not being set correctly:


I’ve identified that this problem occurs because the Ionic Extension runs the app in prod mode and starts the source map server on port 80 when the debugger launches:

[Ionic] samsung SM-G980F Android 13...
> npx ionic build  --configuration=production && npx cap copy android && npx ionic cap run android --target=  --livereload --external --configuration=production
> ng.cmd run app:build:production
[Ionic] Starting source map server on port 80....

However, it seems that these source maps still aren’t being loaded properly…

I found a workaround for now, which involves running ionic cap run android -l --external from the CLI. This runs the app in dev mode, and then I bind the debugger afterward. But it would be really helpful if I could make this work using the Ionic Extension only.

Does anyone have any ideas on how to resolve this issue?

FYI here’s my ionic info:

I have the same issue. I’ve tried your workaround but couldn’t get it to work. :frowning:
