cargo web start with examples doesn't serve the wasm files correctly?

[tangmi]

Hi all, when I run cargo web start --example ... (currently trying this with the cube example in gfx), the server serves http://[::1]:8000/cube.js correctly, but http://[::1]:8000/cube-{build_hash}.wasm returns a 404.

I think the issue is somewhere around here:

cargo-web/src/cargo_shim/cargo_output.rs

Lines 76 to 78 in 2336e68

	"compiler-artifact" => {
	CargoOutput::Artifact( serde_json::from_str( &string ).expect( "failed to parse compiler artifact" ) )
	},

...because we're serving blobs based on compiler artifacts, but the cargo doesn't output the wasm files as a part of the compiler-artifact message:

{
    "reason": "compiler-artifact",
    "package_id": "gfx_app 0.9.0 (path+file:///E:/external/gfx)",
    "target": {
        "kind": [
            "example"
        ],
        "crate_types": [
            "bin"
        ],
        "name": "cube",
        "src_path": "E:\\external\\gfx\\examples/cube/main.rs",
        "edition": "2015"
    },
    "profile": {
        "opt_level": "0",
        "debuginfo": 2,
        "debug_assertions": true,
        "overflow_checks": true,
        "test": false
    },
    "features": [
        "default"
    ],
    "filenames": [
        "E:\\external\\gfx\\target\\wasm32-unknown-emscripten\\debug\\examples\\cube.js"
    ],
    "executable": "E:\\external\\gfx\\target\\wasm32-unknown-emscripten\\debug\\examples\\cube.js",
    "fresh": false
}

Sifting through all the compiler output, it doesn't seem like there is a message that includes the wasm file at all?

Anyways, thanks for the awesome project!

Edit: this might be a cargo bug? I've filed one here: rust-lang/cargo#6810

I think this was closed by rust-lang/cargo#6812! Should be fixed in the next release of cargo?
