## What it is
asm-dom is a minimal WebAssembly virtual DOM library that lets developers build single-page applications entirely in C++ compiled with Emscripten. It handles DOM API calls on behalf of the C++ code, supports a JSX-like syntax via gccx, and offers server-side rendering on Node.js.

## Use cases
- build a single-page application in C++ compiled to WebAssembly
- reuse existing C/C++ code in a web app without writing JS bindings
- share one C++ codebase between desktop, mobile, and web apps
- render virtual DOM diffs at near-native speed in the browser
- do server-side rendering of a C++ SPA on Node.js
- write frontend views with a JSX-like syntax in C++

## When to choose
- you have substantial C/C++ code you want to run in the browser without a binding layer
- you want an unopinionated, low-level virtual DOM you can structure yourself
- you want to share application logic across web and native platforms in C++
- you're experimenting with WebAssembly for DOM-heavy apps

## When to avoid
- you want a batteries-included, opinionated frontend framework with routing and state management
- your team works primarily in JavaScript or TypeScript
- you need a mature, actively maintained library with a large ecosystem
- you can't tolerate the JS-WASM binding overhead for DOM interactions

## Facets
