However for some really complex mini apps, that's another story. But for the rest of those CRUD pages, you can go simple server side rendered.
Again, the issue with htmx is that it pretends like it is not a framework, when in fact, it is just a second attempt at angular 1.0, with even more naive assumptions about web apps.
If it's a sub-function of a bigger ensemble that mostly dies something else then it's fine to call them “mini apps”.
For instance a bank app may contain a text editor for the internal messaging feature of the app, that would count as a min-app in that context.
