Is it still necessary toimport isNill from lodash.isNill instad ofimport {isNil} from lodash?#5742

Answeredbyjdalton

Discussion options

why we need to use

importgroupByfrom'lodash.groupby'importisNilfrom'lodash.isnil'

instead of below?

import{groupBy,isNil}from'lodash'

is this still needed?

There are a bunch ofdifferent approaches and results and most of the are for 2020, 2019 or older.
What is the rightway? can we use a syntax like this

import {groupBy,isNil} from 'lodash' or 'lodash-es'

And what is the difference between the lodashandlodash-es`?
It would greatly appreciated it if anyone shed some light on this topic.

For modern environments you should import from lodash-es.

import{groupBy}from'lodash-es'

Thank you for your response. It would be greatly appreciated if you answer this one:
With this pattern, all the package wont be included into final bundle?

Assuming that none of your other dependencies rely on the base 'lodash' package, that's correct. If they do, however, you will likely get double lodash included.

importgroupByfrom'lodash/groupBy'

What will happen if I use it like this?🧐

Then you'll get doublegroupBy if you have the fulllodash imported anywhere already... Triple if you also havelodash-es, and quadruple if you also havelodash.groupBy... etc... 😢

There are so many different way to accidentally end up with multiple lodash packages installed.
