Example showing how to build a JS/WASM version of a C++ library using modern cmake based on the following:

• https://cliutils.gitlab.io/modern-cmake/chapters/basics/structure.html
• https://gitlab.com/CLIUtils/modern-cmake/tree/master/examples/extended-project

But expanded to include cross compiling to JavaScript/WASM using Emscripten

Dependencies

• CMake 3.17 or better
• A C++ compatible compiler
• Emscripten SDK 1.39.4 or better
• NodeJS 8.0 or later

Visual Studio Code Remote Containers Support

This project includes support for developing in a docker container using the Visual Studio Code Remote - Containers extension. The configured docker container includes emscripten, cmake and gcc so you can build, debug and run this project immediately without having to deal with toolchain dependencies. The default build task (shift+control+b) is to configure, build and run the tests

NOTE: If you don't use VS Code but want to use Docker, you can try using the Dockerfile in the .devcontainer folder.

Building JS/WASM

The requirements are:

• Docker (to build JS/WASM Emscripten)

To configure, build and test:

./build.sh

After building, you can run the browser based test by running an http server at the root of this project and opening the file test/browser/index. I use HTTP Server / HTML Preview
