I didn't write any JavaScript, and other shortcuts
This is not always possible. Even a functionally simple project like twitter or mastodon could not work without javascript. Heck, even a modern ecommerce store could not work with simple html these days. Modern web applications are interactive and &quot;alive&quot; and simply require front-end application as well and not just plain old html. I would say to go the other way round and figure out how to make vuejs&#x2F;react apps into web assembly binaries to be run like desktop applications in web browser. The user has no need to see the source code or fiddle with network connectivity.
