React Native importing only what is needed

Question

Say I have the following:

import validator from 'validator'

and in my code do:

validator.isEmail(txt)

Would that import the entire validator and increase the overall package size?

---

if, how do I avoid this?

Answer 1

Your statement will import the whole validator. What are you looking for is this

    import { isEmail } from ‘validator’

isEmail should be e exported in the source file.
