Motivation

asm-dom is a minimal WebAssembly virtual DOM to build C++ SPA (Single page applications). You can write an entire SPA in C++ and compile it to WebAssembly (or asmjs as fallback) using Emscripten, asm-dom will call DOM APIs for you. This will produce an app that aims to execute at native speed by taking advantage of common hardware capabilities, also, you can use your C/C++ code without any change, you haven't to create a binding layer to use it (as we have to do if we want to use a C++ lib from JS). Basically we are creating an app in C++ that call javascript if needed instead of the opposite. You can write only once in C++ and share as much code as possible with desktop/mobile apps and web site. If you want to learn more about performance, please see this.

How can I structure my application with asm-dom?*

asm-dom is a low-level virtual DOM library. It is unopinionated with regards to how you should structure your application.

How did you come up with the concept of asm-dom?*

At the beginning asm-dom is born from the idea to test the powerful of WebAssembly in a common use case that is not gaming, VR, AR or Image / video editing. Unfortunately, at the moment, GC/DOM Integration is a future feature 🦄, so, asm-dom isn't totally developed in wasm. All interactions with the DOM are written in Javascript. This is a big disadvantage because of the overhead of the binding between JS and WASM, in the future asm-dom will be even more powerful, anyway results are satisfying.
