Ah, too bad. wasm is still considered an experimental LLVM target (at least for LLVM 7), so LLVM needs to be built in a special way (LLVM_EXPERIMENTAL_TARGETS_TO_BUILD CMake variable) to enable it.

I guess your problem is that you cannot *link* wasm; that will only work with v1.14 for distro packages (without integrated LLD). The targets wasm32 and wasm64 are missing in the Arch package.

I don't use .NET myself, but I once reverse engineered a signalR client for some data feed I wanted to listen to, so I am a little familiar with it. But why not use gRPC over websockets, or real-time graphQL? Spasm has bindings to the browsers websocket and I don't think its hard to connect that to a D client implementation of gRPC or graphQL. Also, what are the limitations that prevent the D runtime (just druntime, not Phobos) from being ported to WASM? The real blocker was the GC. In wasm the address space starts at 0, so almost everything looks like a pointer :) But now that we have a precise GC, that should be solved. Maybe some issues with threaded since Webassembly is currently single-threaded (although multithreading is on the roadmap.) So yeah, there aren't many blockers. I did actually try it a couple of months ago, and got pretty far. But I wanted to keep things lean and mean and decided to constrain it to betterC. I am first going to see how well I can implement some material-ui components. That is going to be the litmus test for the SPA framework part of spasm. Again, nice work! Thanks. A lot of praise goes to the LDC team and the fact they build it on top of LLVM.

This is really cool; nice work! Over the past 6 months I've been working a lot with .Net's WASM implementation, code-named Blazor. I estimate I can build GUI applications at 20% the development cost, while also getting portability, and a more rich features set (alpha transparency, flow layout, SVG, video, GL, etc...). Bundled with Electron, it makes for a convenient cross-platform application GUI framework. It's actually changed everything I do for desktop and ARM Cortex-A embedded GUI work (still need something for Cortex-M, though), and I don't think I'll be going back. The upcoming .Net Core 3.0 will include something called Razor Components, previously called Server-Side Blazor. It uses Microsoft's SignalR (think web sockets) to create signals on the server, slots on the client, and to push UI render changes to the client. Are you aware of SignalR, and do you see something similar eventually being added to Spasm?

So you can do things like this:
---
import spasm.bindings;
import spasm.dom;
import spasm.types;
extern (C) export void _start()
{
auto elem = document.createElement("div").as!HTMLElement;
elem.style.backgroundColor = "green";
elem.innerHTML = "BLA BLA!";
elem.addEventListener("mouseover",(event){
console.log("onmouseover");
console.log(event);
console.log(event.as!MouseEvent.clientX);
});
auto root = document.querySelector("body").front;
root.appendChild(elem);
}
---
And have it Just Work.
