WebAssembly C/C++ Examples

Overview

These C and C++ examples demonstrate how to create different types of WebAssembly (wasm) programs with the twr-wasm library.

These are good examples to use as starting points for your own Wasm projects.

These examples are a good place to learn how to configure clang and wasm-ld to compile and link C/C++ code for use with WebAssembly (wasm).

Each of these examples are designed to illustrate how to use a feature of twr-wasm.

Name	Description	Link
helloworld	A very simple C Wasm example to get you started	helloworld
stdio-div	This simple C program demos inputting and printing characters to a `div` tag	stdio-div
stdio-canvas	This simple C program demos writing and inputting from a `<canvas>` tag that twr-wasm configures as a windowed "mini-terminal"	stdio-canvas
balls	These fun Bouncing Balls are written in C++ and demo the 2D drawing APIs with a C++ Canvas wrapper class	balls
maze	This is an old Win32 program ported to wasm and demos the 2D Draw APIs	maze
fft	A demo of calling a C library to perform an FFT that is graphed in TypeScript	fft
callC	A demo of passing and returning values between JavaScript and Wasm module	callc
tests	twr-wasm unit tests	tests
tests-user	"cli" for tests using libc++ and `<canvas>`	tests-user
tests-libcxx	Smoke test for libc++. Shows how to use libc++.	tests-libcxx
