I read this here - https://www.thedevelobear.com/post/5-things-to-improve-performance/ - that doing importing all things from a library will not allow tree shaking to remove it, even if it is not used. I don't believe this, is it really true? I would think that tree shaking would identify that none of the functions except a couple were used, and then remove those.
There is a really easy way to reduce bundle size by just checking your imports. When performing methods or components from 3rd party libraries, make sure you import only the things you need, not the whole library itself. For instance, if you’re using lodash and need the fill method, import it directly instead of calling it on lodash object:
// Instead of this import _ from ‘lodash’ let array = [1, 2, 3]; _.fill(array, '
