My nextjs project calls the main page, and 98% of unused bytes exist in one chunk of chunks.
When I looked into the code, there was a red line marked on this type of code.
"use strict";
eval(...)
I'm not sure what that means. Does it mean that the unused code was imported and used?
I need your help and a keyword to find a clue.
you're running your tests in a development environment. that's why you're shipping so much unused JS. to fix this run next build to generate an optimized bundle.
in production, if you want to figure out why a package was imported I suggest using bundle-analyzer.
as for what they are.
