We recently used Turborepo -- https://turborepo.org/ -- for a project that started as a two Electron-based builds that quickly escalated to a three Electron-based build. Once we had it set up for the two, it was quite easy to add one more. Our shared components were in a central package while custom ones existed in their respective app directories.

The nice thing with this type of separation for us is being able to target CI/CD scripts to specific apps. Previously we were using targeted dev script logic to initiate the different app builds which just wasn't maintainable. This new approach this time around made for Electron deployments to be super simple, consistent, and repeatable.

All this was done by two team members on dev side.
