Electron app with multiple build variants(additional features than base app) with changes in package.json changing everytime, How to automate this?

I am working on an Electron app that has a package.json file in the root folder. There are 3 build variants that we release for the same.

1. Base App
2. Base App + Feature1
3. Base App + Feature1 + Feature2

I am facing an issue since point 3 needs some npm modules that my Base app doesn't need. Hence there is a change in package.json file for each build variant. Here are my doubts,

• Can there be multiple package.json files which will build specific build variant?
• Can this be done using one package.json file, If yes, how?

Thanks in advance.
