Google Lighthouse Pagespeed

[azheng003]

I'm working on a site and I'm having trouble improving the pagespeed scores. I used the webpack analyzer and tried removing a few big modules but that didn't make a huge difference. Is there something glaring that I'm missing? I'm not quite sure what a good webpack analyzer result looks like. Should I be concerned about the modules outside of commons.js? Thanks in advance.

Have you checked your packages against bundlephobia?
I've fixed bad scores in the past by removing packages that introduced huge boileplate html, css and js code.

Create a branch and start removing stuff, commit, and lighthouse test.

I agree with @decimoseptimo , from my experience what you have is far too much but it sort of depends on what you're trying to accomplish. Also, make sure to get your site behind a CDN or something similar, HTTP2, compression, etc.

That will give you the most realistic result in lighthouse.

Removing a bunch of packages help my score a little bit, but changing the way my fonts were loaded and pre-loading the fonts helped a lot. There's still more progress to be made though.
