Shred no zlib library

hi
there is always this caution when loading app

no zlib library

does that means that i need to put
https://github.com/brianloveswords/zlib-browserify in the folder

in shred this is the relevent code snippet
try{zlib=require(‘zlib’);}catch(e){console.warn(“no zlib library”);}
please advice
thanks

It’s not necessary , I would just comment out the snippet.
