Show HN: µJS, a 5KB alternative to Htmx and Turbo with zero dependencies

I really like these sorts of frameworks from an architectural perspective, but what's the use-case? Maybe I'm too SPA-pilled, because to me all the fun of Web development is in providing really fluid, skeuomorphic experiences like those enabled by, eg pragmatic-drag-and-drop[0] or yjs[1].

I just struggle to envision what application benefits from the efficiency that this or htmx offer, but from neither the ultra-interactive, nor the ultra-collaborative. Maybe updating stock ticker prices? Fast-service back-of-house ticketing displays?

I would love to feel called to reach for this library.

I love that drag/drop, BTW. Really nice. Gonna see how I can use that.

Aside from being able to build fast websites: https://youtu.be/fWfIf7Vfjec

Relying on server side as the source of truth inverts complexity. Suddenly 90% of the modern webs problems evaporate. Turns out building everything on top of a shadow dom in the client creates a boatload of unforced errors.

The sweet spot is everything between a static website and a full SPA, which is actually most of the web. Think e-commerce (filtering, cart updates, pagination), dashboards (refreshing metrics, notifications), admin interfaces (inline editing, form submissions), content-heavy sites (live search, comments, modals). Basically any app where the primary interaction is 'user does something, server responds with updated content'. For drag-and-drop kanban boards or collaborative editors, you're right, µJS is not the right tool. But those are a small fraction of what gets built every day. Most web apps are glorified CRUD interfaces, and for those, server-rendered HTML fragments are simpler, faster to develop, and easier to maintain than a full SPA.
