My last info was, that Hoot is not 100% compatible with all of Guile (at least not its extensions!?) - so my question would be which libraries and frameworks you recommend for web development?
When you are looking for “Hoot web framework” online, there is no search result, so maybe a blog post or something like that is good for SEO.
Thanks in advance 
Unfortunately, I don’t have a Guile web framework that I can recommend. Guile provides the essential HTTP server/client pieces, SXML is good for dealing with markup, and Hoot can be used for client-side stuff if maximizing use of Scheme is what you want, but there’s nothing that composes everything together for a Rails-like web development experience.
I understand Hoot is still meant to be used for web development?
Yes, but it’s not as “batteries included” as we would like at this time. We’re still building up the ecosystem around it.
What about artanis web framework ? I was able to get the newest version sqlite3 working with it.
I haven’t used Artanis, but you could certainly try to combine it with Hoot and see how it goes!
I am working on a reactive client web framework similar to React that uses Hoot! It’s not finished yet, but it’s called guile-whipped!
