A simple hello world Compose Web app (wasm - Box + BasicText) take 3~4 seconds to download and be rendered on a web page.
no dependencies other than compose foundation

08/21/2024, 1:25 PMI’m not sure on the specific details; But yes. I think Google gives your SEO a penalty if you page renders slowly;

08/21/2024, 1:26 PMthis is irrelevant then. compose web uses canvas which is not read by search engines

08/21/2024, 1:27 PMSEO was already killed because of canvas, now with extra overkill for the render speed 😂

08/21/2024, 1:28 PMyup. if seo is important for you, don't use compose web

08/21/2024, 1:52 PMthat being said, I would be so happy if we get to the point that simple hello world apps take <1 second to be rendered

> What is transferred size?
transfer size i think is 3mb? the wasm file at least seems to be 3mb at the js console
> Is compression is on server side
I don't know what that means. i am serving the output files via the express static folder
> Is it optimized/prod build?
not sure. i use
./gradlew webBrowserDistributionb

08/21/2024, 2:10 PMwhich kotlin version do you use?
bashor
08/21/2024, 2:13 PMas I see, compression is on, 3.2 MB it’s skia, there is 458 KB binary with other parts (libs, including compose + app)

08/21/2024, 2:20 PM Copy code
kotlin = "2.0.0"
compose = "1.6.11"e

08/21/2024, 2:26 PMIt took about 1.5 seconds on my first visit to https://composablesui.com/wasmdemo/ on my phone, and is pretty much instantaneous after that (I'm assuming it gets cached)

08/21/2024, 5:01 PMYou can try to play with preload to force loading wasm files earlier
bashor
08/21/2024, 5:03 PMit may save you 1-2 seconds

08/21/2024, 5:17 PM@bashor what do you mean by earlier? earlier than what?
