hello ohans, pardon me, but u didn't mention in book for required package need to be installed, I try manually finding it, but little worry installing wrong package 😅 hehe

Hello @kraizt , I sort it just calling from the console (once inside the project folder) 'yarn add shortId', 'yarn add txtgen', 'yarn add faker', 'yarn add lodash'. If you already installed node these packages are already in your environment , hope it will be useful !

use yarn add shortid txtgen faker lodash

Hi Ohan! I'm having a syntax error on line 12 actually. I'm new at using lodash. I tried removing the three dots and I'm still getting the syntax error.

Note that faker js has been discontinued by its creator.

I have written an alternate script that uses only Falso to generate the same content.
