For future reference, it turns out adding Electron to a Vue app you've already built isn't all that hard.
You might need to migrate from Vue CLI 2 to Vue CLI 3, but that doesn't take much effort.
Make sure you have the latest version of Vue installed
npm i -g @vue/cli
vue add electron-builder
and you're good to go!
This command adds files and scripts we need to build our regular Vue app into an Electron app. It also allows us to preview the Vue app in a new Electron window. This way, you can debug it there other than in a regular browser.
It adds a
background.js file in your
/src/ folder and a few commands like
npm run electron:build
npm run electron:serve
package.json. Use this to start the development version of your electron app. You can still start the regular app in a browser by calling
npm run serve
