How to debug theia extension?

[young47]

I developed a theia extension, and run using commands: yarn && yarn build:browser && yarn start:browser, I can debug the frontend code in browser. but how to debug the code running in backend(nodejs)？

The most straightfoward way to debug the backend code is to launch the backend via your IDE. For example if you're using the Theia IDE or VS Code, you can use a launch configuration like this.
