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 !

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.
