@tiero can you explain problem with standard go we already using? what should be solved by this?

[tiero]

The WASM is 35MB. The limit on Cloudflare Pages is 25MB. Due to his popularity we expect many other users to want to host JS apps that uses Ark SDK there.

@sekulicd the problem is: ark-sdk.wasm is >35MB in size:

• We host the clients on Cloudflare's Pages
• Cloudflare's Pages does not allow files >25MB in size
• This means we need to host the wasm file in a different service
• Which is a pain when developing with quick iterations

A different approach would be to build the wasm into different files:

• 7 files with 5MB each is ok, one with 35MB is not
• I think is possible to divide the go code into into modules and then generate different wasm files

I would give TinyGo a chance, looking into possible optimizations https://tinygo.org/docs/guides/optimizing-binaries/

Other option is also to use compression when compiling and then decompressing in the browser

@tiero @bordalix update on this: TinyGo doesnt support native net/http pkg, there is ported https://github.com/tinygo-org/net pkg but replacing standard pkgs with TinyGo doesnt seem nice option?
Tried with compressing but didnt make it work yet, will try more.
