Too much JS downloaded with simple starter app

[agnar-nomad]

Hello team, so happy to find Waku and start experimenting with it!!

When I build and start up the simple starter example, I am surprised to see almost 0.5 MB of JS downloaded to the client. One of the compelling features of RSC for devs is smaller app client bundle size.

I wanted to ask about and index.js file of 170kb (first line) being downloaded on page start/refresh.
But even more surprising is the last line, 234kb of testing-library.js being shipped to the browser.

I ran yarn build > yarn start > open localhost:8080

I am still working on my machine only, I guess its different when deployed on a server...?
I might certainly be off track completely, but could you please explain the above points?

Hi, thanks for trying it out! Feedback is very appriciated.

What's contentScript.js? It doesn't seem related to Waku.

I guess 170kb is mostly due to react libraries. Even with RSC, we still load the full react library. (We really wish react library becomes code splittable...)

Apologies, that second weird thing comes from a browser extension.

A Next.js template app costs only about 70kB on the client. I will be eager to see if Waku can be compressed a bit more.

is it because of compression on transfer? or do you compare the content size?
On our discord server, someone compared the minimal apps similarly.
