I thought it did. But on my Moto G6 Play phone, CloudT stored as an home screen app loads properly in Airplane mode. So saving as a home screen app caches more aggressively, I guess. I need to add a appcache manifest, or the newer standard, a service worker and it cache on Chrome desktop too. As to Node.JS, Node.JS is a combination Javascript runtime and package management system. None of the CloudT javascript code runs in the server, just in the browser, so it wouldn't benefit from the Node.JS javascript engine. That said, Node.JS can run some simple webservers. CloudT at this point is a static html + javascript site, which means it has no server side code. So it would run locally under any web server and maybe even from a local directory without trouble. But there are many webservers that will run on a Pi. The benefit of Node.JS would be if you want to access some hardware. Say a physical serial port. It could be exposed to CloudT from Node.js "SerialPort" library as a Websocket to the front end running as a web app. But if I get the browser caching set up (thought it was!), I think the browser would end up being the simplest offline solution. Just browse Cloudt once with your browser, and it's effectively "installed". -- John.
