Supports building and loading optimized WebAssembly ( powered by emscripten toolchain )

We would like to use WebAssembly in our web application.
But, not every browser supports WebAssembly. So, we must use it together with not WebAssembly module ( like asm.js ).

Currently, some languages supports WebAssembly ( Go, Rust, C/C++, ... ).
Go and Rust are famous and popular language. Also, they aggressively support WebAssembly. But, they not provide fallback plan from WebAssembly.
Therefore, we cannot select them.

On the other hand, Emscripten can compile C/C++ to WebAssembly and pure javascript with asm.js. So we select it for WebAssembly because in this fact is very attractive for us.

We know WebAssembly's binary size and memory usage is too large. But, we want to use it compactly.

We provide Dockerfile and docker image (by DockerHub) for building WebAssembly.
Image includes wasm-builder and it supports building optimized WebAssembly.
If you doesn't use wasm-builder, compiled WebAssembly use 16MB memory at least. But, if you compile with wasm-builder, it use only 64KB !!!

We provide wasm-loader.js for loading WebAssembly.
wasm-loader.js provides WasmLoader class and it provides load method only.
load method call dynamic import statement for loading wasm module.
First, load method try to call dynamic import callback for wasm module. But if your browser doesn't support to WebAssembly , load to call dynamic import callback for asm.js module.

npm install --save @knocknote/wasm-loader
