You can, but the law of diminishing returns applies. The more stuff you use around roughly the same idea, the harder it will be to manage, the larger your bundle size will be.

hmm, then I have to re-think my idea of making a website for a volunteer orginisation to keep tracks of the subscriptions, members and what toys are borrowed by who

Ah, I should've mentioned - I know 0 about Luminus. I was assuming that it's a full-stack framework that also provides some UI affordances. If it does not and it's only a backend framework, or if you won't use that UI part of Luminus, then using re-frame should be just fine.

oke, I used Luminus as example. I could also be using a lot of libraries myself

just learning re-frame and wonder if I make a good choice to make that site in the future with clojure and re-frame

I'd say go for it.

Of course as clojure developer you said go for it 🙂

but I think still a lot to learn before I can make that site

If there are no constraints whatsoever, it seems to be a good project where you will be able to learn a lot. If there are time constraints, of course go with the option you already know the best.

no time constrains. For me this is hobby so I have a lot of time

can you describe more of what you want to do with the website?

I will try. On the organisation where im volunteer. People can borrow for 4 weeks toys if they have a subscription. So on the website I would make some pages where all the toys are displayed on categories like a web catalog so we can keep track of whcih toys are borrowed by which person. Also we want to know if theta person has paid for the subscription. Maybe later I will add code so we also can keep track what amount of fee someone has to pay if the person is too late with brining back the toys and if the person has paid the fee

We have now a system on a computer to keep track of the borrowing but that one cannot talk to our web catalog

Luminus provides you with the full stack, including an optional re-frame frontend. So you definitely can do what you suggested.

glad to hear
