I think what you're looking for is mithril. It checks every one of these boxes, except it has a nicer developer experience and still has lifecycle methods, which seem much easier to reason about and test than Aberdeen. Seriously, check it out. You'll be impressed. You can learn the API in a day, and it's super stable and thoughtful. I've been using mithril for a decade and the only time I don't reach for it is if web components solve my problem (smaller projects, non-SPAs) https://mithril.js.org https://mithril.js.org
