Where can i find the soucre code of lab?

Hi folk,

i am newbie in LFW211. I try to follow the lab written in pdf and it said there is some lab source code for me to test run. However, i cant find it under resources. May i check how to get/download the lab source code?

For example: Lab pdf will say below but no source code can be downloaded....
"
The labs-1 folder contains an app.js file. Start app.js with Node in Inspect Mode, but with
the application immediately paused on the first line of executable code."

Thank you for your help
