Remove unused imports

// Map won't be eliminated when bundling
import Map from 'lodash.map'

There are non-pure modules with side effects. Is there any way to remove the unused import regardless of side-effect. Possible related rollup feature Thank you.

@j-f1 Thank you. So I guess the burden of pruning unused pure external imports should be on the bundler end, not babili.

@boopathi You could remove the unused named exports (and then an empty {}), then remove the unused default export:

import foo, { bar, baz } from './quux'
import foo, {} from './quux'
import foo from './quux'
import './quux'

This way, you could shorten the imports without side effects.
