WASM file size?

[ivnsch]

Thanks for creating this template!

Creating the release build, as specified in the readme, shows this warning:

WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
Assets:
fonts/fa-solid-900.svg (775 KiB)
images/pfbg_992@2x.jpg (575 KiB)
images/pfbg_768@2x.jpg (354 KiB)
images/pfbg_2000.jpg (270 KiB)
main.js (1.17 MiB)
main.wasm (2.04 MiB)

Notably: main.wasm (2.04 MiB)

I checked the Yew optimizations guide (https://yew.rs/advanced-topics/optimizations#cargotoml) and was able to reduce it to 1.17 MB by adding this to the cargo.toml:

[profile.release]
# less code to include into binary
panic = 'abort' 
# optimization over all codebase ( better optimization, slower build )
codegen-units = 1
# optimization for size ( more aggressive )
opt-level = 'z' 
# optimization for size 
# opt-level = 's' 
# link time optimization using using whole-program analysis
lto = true

Still, 1.17 MB seems large (without all the assets). Would it be feasible to work on optimizing this template (including e.g. inspecting the binary with Twiggy)?

That sounds like a great improvement. Would you mind creating a PR for this?

I agree that especially the WASM binary could be smaller. If you have any ideas, I would definitely welcome them.
