Slides and Code for my talk "WebAssembly - Running C++ and Rust in a Web Browser"

The folder code contains the examples for generating and running WebAssembly from C++ and Rust code.

Compiling C++ to WebAssembly using just clang.

Dependencies:

• clang compiler
• Python for running the web server (can be exchanged easily for any web server you want)
• wasm2wat if you want to decompile the wasm file to human readable WAT (WebAssemblyText) yourself

Usage:

• compile.sh will compile the C++ code to wasm.
• run.sh will start a web server on port 9000 using pythons http.server (then you can go to localhost:9000/index.html)

Compiling C++ to WebAssembly using emscripten. Both WebAssembly embedded in a HTML webpage for running inside the browser and freestanding WebAssembly for running with a wasm-runtime directly on the machine are generated.

Dependencies:

• Emscripten
• Wasmer for running the freestanding WebAssembly example outside of the browser
• Python for running the web server (can be exchanged easily for any web server you want)

Usage:

• compile.sh will compile the C++ code to wasm.
• start.sh will start a web server on port 9000 using pythons http.server (then you can go to localhost:9000/hello.html)
• run_standalone.sh will run the freestanding wasm example using the wasmer runtime

Compiling rust to WebAssembly and running it in the browser.

Dependencies:

• Rust toolchain
• NodeJS
• wasm-pack

Usage:

• build_run.sh will compile the Rust code to wasm and start a webserver on port 8080 (then you can go to localhost:8080)
