I love the idea of applications which exist in one file which you can run anywhere. I've been working towards this with my serverless platform; you can build complex data-driven apps with just one .html file and mostly declarative HTML markup (thanks to web-components which are loaded from a remote server). With modern browser features, you don't need a bundling system. Once you do away with it; a whole universe is opened up. The ability to load .html files over the file:// protocol is a powerful, often neglected feature. In practice, it means you can double-click an HTML file and it runs an app in your browser instantly.

Sadly a lot of browser features are inaccessible from non-https contexts.

  Don't most (all?) browsers consider file:// and localhost to be secure for the sake of enabling those features? https://developer.mozilla.org/en-US/docs/Web/Security/Defenses/Secure_Contexts#potentially_trustworthy_origins https://developer.mozilla.org/en-US/docs/Web/Security/Defens...

      So that's why I have to keep booting a Windows 7 computer in order to use an html file I saved 10+ years ago? Some dumb shit android app.

  or you could use something like caddy (https reverse-proxy, local cert), and have a dedicated ws running in the background that serves your files

How are you approaching the development of your single file html apps, is there any examples publicly available, sounds very interesting.

> I implemented the game three times in total: once in C for the i686 Visual C platform using WinAPI, once in C for the x86_64 Linux platform using clang and X11, and once in JavaScript for the browser using HTML5 Canvas. The OP actually wrote two native applications instead of just instantiating a browser.
