The Clojure's approach is to favour libraries over frameworks.
We use Clojure on various style of applications (mainly web and API based), hosted on widespread infrastructure technologies of Cloud Providers (Kubernetes, PostgreSQL, Kafka, etc.) and it's a breeze: here are our reasons for choosing Clojure https://defsquare.com/blog/why-we-bet-on-clojure
If you want to look at libraries where some people have settled, here are our _opinionated_ takes on libraries that we use on almost every project:
- HTTP: Ring is the de facto way to manage HTTP request (see https://github.com/ring-clojure/ring/wiki/Concepts) supplemented with various "Middlewares" for web-related concerns (security, logging, content encoding, etc. see https://github.com/ring-clojure/ring/wiki/Standard-middlewar...). Jetty and Aleph are common web servers (and https://gith

ub.com/clj-commons/aleph) that implement Ring interface.
- Routing: Reitit (https://github.com/metosin/reitit)
- Single-Page App: shadow-cljs for the build concerns (https://github.com/thheller/shadow-cljs), Reagent with Re-frame for complex/large app (https://reagent-project.github.io and https://github.com/day8/re-frame). Even if we now prefer using HTMX (https://htmx.org) and server-side rendering (Hiccup way of manipulating HTML is just amazing, https://github.com/weavejester/hiccup).
- Schema management: Malli (https://github.com/metosin/malli)
- Lifecycle management: Mount, Integrant or Component (https://github.com/tolitius/mount https://github.com/weavejester/integrant and https://github.com/stuartsierra/component)
- Config management: Aero (https://github.com/juxt/aero) and environ (https://github.com/weavejester/environ)
- Log: μ/log (https://github.com/BrunoBonacci/mulog)
- Time: https://github.com/juxt/tick
- Testing: https://clojure.github.io/clojure/clojure.test-api.html and Kaocha for the runner (https://github.com/lambdaisland/kaocha).
- Package and project management: tools.deps is simple and powerful (https://clojure.org/guides/deps_and_cli)
For infrastructure stuff (PostgreSQL, Keycloak, Solr, Kafka, etc.), just wrapping the underlying Java library or driver is often enough, and there are lots of wrappers for easing the integration. And we implement Hexagonal architecture style to put all of that in place.
Don't be afraid a libraries not moving a lot recently, it's a sign that the library is mature and battle-tested.
Clojure is a joy to use every day :)
