Maybe, but I haven't touched Vue in a long time.

For sure. I still have some projects that use what I like to call "jQueryScript", where there's just a bunch of unprocessed (or only minified) JS files with `$("#foo").click(function() { ... })` stuff everywhere. Looking back, it wasn't all that bad.

I just wish there was a pattern that is simple, works with plain, modern JS without any big dependencies (I don't want 600 node modules installing a frontend framework, please) and is easily modular and integrates nicely with other stuff (so likely either manipulating DOM nodes directly or using WebComponents)

Out of protest, I have some smaller projects that have their GUI templates stored in `<template>` tags and manipulated with plain Javascript. Anyone that opens the code will see it and think "wtf?" and then be like "oh... uh sure". The largest one I had written was 1000s of lines of code like that, kinda like a classical MVC pattern where a view (class manipulating DOM nodes) renders a model (a JS object or class). The controller would subscribe to custom events (defined by the view), update the model and call `render()` on the view. It had a lot of small classes, which was a bit too verbose to my liking.
