This is an intellij plugin that wraps the functionality of the Dalibo pev2 vue component. https://github.com/dalibo/pev2
The user interface is a vue.js webapp that is embedded through embedded chromium into an editor tab. The vue js app is built using vite and standard vite commands apply. It's located at src/web
I manually copy the built files from src/web/dist into src/main/resources/webview
