feat(wasm): async compile + call JS func from Rust #10

DrSensor · 2018-08-25T03:28:29Z

This update is about how to compile/load wasm code asynchronously. Also, it adds the ability to import and call JS function from Rust (wasm) code. The async compile/load exists in case that someone needs to load big .wasm code without blocking the process.

^{[FYI] just for future references}

WebAssembly.Module can be efficiently shared with Workers, and instantiated multiple times. Also, according to this spec, it serves as the basis for dynamic linking. That's mean WebAssembly.Module are basically just like .dll or .so file. If this true then there is also possiility to implement hot-swapping 🤔.

📥 ability to call JS function inside Wasm code [ci skip]

💔 deprecate `promise` in favor of `async` [ci skip]

🐀 the use case would be having lifecycle hook in wasm code

[ci skip]

this will dismiss warning: ```console 'buffer' is imported but could not be resolved – treating it as an external dependency ```

🔪 wasm code to big for test, need to enable LTO ❌ smoke test fail! use export {default} instead *
