Hi, sorry, missed your question. Try this: import { filterDeep } from "deepdash-es/standalone"; example:

Hi Yuri thanks for the reply. I tried that. But I am getting this error while running unit test using jest..

Well, looks like it's a Node version / Babel issue. Or you probably need to learn what is this "transformIgnorePatterns" config option. I googled "jest Unexpected token 'export'" and found this discussion:

I work at Lam Research and our team has really liked the deepdash library. We have implemented it everywhere but we are stuck now.We can't run any unit test.I followed the link you have given in above message. But its not helping. I understand that this is not deepdash problem. I guess its jest configuration problem. We are trying hard for last 2 days to fix this jest configuration problem. I will keep you posted

Could you create some example github repo, where your problem is reproducible? I will take a look then.
I added jest test to that codesandbox
and looks like it's working, so maybe something specific to you techstack is hapening. So again, lmk if you will have reproducible isolated issue in some example repo.
Thanks Yuri for code Sandbox..I will see how I can create a github repo..Will update you soon
