Mentioning μ/log and no mention of timbre (https://github.com/taoensso/timbre), that is an odd omission. Malli is a great mention, but there ought to be a mention of clojure.spec (https://github.com/clojure/spec.alpha) which has much more mindshare.

* 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).

You can already develop with ClojureScript on the back-end. A popular ClojureScript compiler, Shadow-CLJS (https://github.com/thheller/shadow-cljs) has a target for Node among many others.

Hi, I'm looking at Clojurescript again after not having paid attention to it after several years. Are you saying that shadow-cljs does something to deal with the, "I have no idea if this library I want to use works with the Google Closure compiler," problem? If so, what? I'd really like to know.

I don't know, the community in general tend to use macros that are well written. I keep seeing core.async being used (`go`) in Clojure projects, and also various macros for writing HTTP servers (compojure being a popular one which main code interface is a macro `defroutes`).
ClojureScript projects also routinely add support for making asynchronous code look synchronous (like `async/await` in vanilla JavaScript) via macros. shadow-cljs's `js-await` being one of the well-written ones: https://github.com/thheller/shadow-cljs/blob/49fb078b834e64f...
Usage:
```
    (defn my-async-fn [foo]
```

Unclear what "rendering a webpage" entails exactly.
If you want to do frontend development, you can give shadow-cljs a try, the quickstart is pretty quick: https://github.com/thheller/shadow-cljs#quick-start
If you want to just render server-side HTML, something like compojure (HTTP routing) and hiccup (Clojure data -> HTML) is pretty easy and quick to get started with (https://gist.github.com/zehnpaard/2071c3f55ed319aa8528d54d90...).
If you want to generate HTML files to serve with nginx/whatever, you can just use hiccup and `(spit)` the resulting HTML to files on disk.
