This is a great library. I couldn't find any informations about data storage in HTML5 through Emscripten, but I checked the example and it saves to cookies. Very good job in simplifying work from any side.

One major defect is that it has no precise tutorials how to fix something and some files doesn't have valuable informations like VSCode template. To compile many files I spent couple of days due to no EXACTLY information on wiki (again). Android application gets stuck when I press the back button, I'm asking for help on Discord and nobody cares. It's a great library, but it needs MORE DOCUMENTATION! People can't waste more time for guessing.

Nevertheless, it's a very valuable tool and keep updating, it's worth it!
