WASM Toolchain

Emscripten

Toolchain image for Emscripten, a source-to-source compiler that runs as a back end to the LLVM compiler.

Usage: Create hello.cpp and compile to hello.wasm

New-item hello.cpp -Value "#include <iostream>
using namespace std;
int main() {
  cout << `"Hello World`" << endl;
}"

docker run --rm -v $pwd`:/target mziyabo/emscripten emcc ./hello.cpp -o hello.wasm

Wasmtime

Executable image for Wasmtime, a JIT-style runtime for WebAssembly.

Usage

Execute ./hello.wasm in wasmtime

docker run --rm -v ${pwd}:/target mziyabo/wasmtime ./hello.wasm

Known Issues

• Emscripten image is a little beefy
• Might need to address adding link library and includes directories
