That notation has nothing to do with ES5, it is CommonJS. What do you mean by "for es6 imports"? Do you want to replace them with the ES6 module syntax? – Edholm

If you have Eslint correctly configured which includes no-unused-* you can easily using the fix command: blog.jetbrains.com/webstorm/2016/08/using-external-tools – Leffler

@Leffler that's a good idea. thanks. – Cleodell

If fixing the problem for each file individually is not an option for you, try using ESLint auto-fix per @Hitmands suggestion
