Aggregated on: 2023-12-30 19:27:59

So I've been working on a project for a while to create a real-time, high-performance JavaScript Chart Library. This project uses quite an ambitious & novel tech stack including a large legacy codebase in C/C++ which is compiled to WebAssembly using Emscripten, targetting WebGL, and a TypeScript API wrapper allowing you to load the charts in JS without having to worry about the underlying Wasm. First Up, Why Use Wasm at All? WebAssembly is an exciting technology and offers performance benefits over JavaScript in many cases. Also, in this case, a legacy C++ codebase already handled much of the rendering for charts & graphs in OpenGL and needed only a little work to be able to target WebGL.
