Simple webserver with chat functionality via WebSocket made for low.js/Node.JS
Run with bin/low lowjs-webserver-example/index.js from lowjs directory and then open the links given with the web browser.
The https link will give a certificate warning, which is correct, because the certificate is self-signed.
On low.js based microcontrollers you can alternatively not copy node_modules and install ws from the graphical package manager. This has the side effect of faster program startup as the packages from the package manager are packed more efficiently than separate files.
