For another excellent scripting solution that has - fast startup (no compilation) - uses a real language - easy to upgrade beyond a script - has tons of excellent dependencies baked-in

Look no further than babashka! It’s a clojure interpreter that has first class support scripting stuff. Great built in libs for shelling out to other programs, file management, anything http related (client and server), parsing, html building, etc.

Babashka is my go-to tool for starting all new projects now. It has mostly everything you need. And if it’s missing anything, it has some of the most interesting and flexible dependency management of any runtime I’ve ever seen. Via the “pod protocol” any process (written in go/rust/java whatever) can be exposed as a babashka dependency and bundled straight in. And no separate “install dependencies” command is required, it installs and caches things as needed.

And of course you keep all of the magic of REPL based development. It’s got built in nrepl support, so just by adding on ‘—nrepl-server 7888’ to your command, you can connect to it from your editor and edit the process live. I’m building my personal site this way and it’s just SO nice.

Sorry for the rant but when superior scripting solutions come up, I have to spread the love for bb. It’s too good to not talk about!!
