Linux Plesk hosting

[mcaltindal33]

Hi guys,
I bought a linux plesk hosting and I'm withdrawing the project from the git account, I'm installing yarn at node js and a blank page appears. config inside the static folder.i'm editing in js, I couldn't run it somehow, or there's a problem with me, or as a result, can you direct me step by step what I need to do in the latest version?
i even searched on youtube, but I couldn't find some kind of solid source.
