Michiel Borkent (borkdude (Michiel Borkent) · GitHub) will be presenting
“nbb: ad-hoc scripting for Clojure on Node.js”

nbb (GitHub - babashka/nbb: Ad-hoc CLJS scripting on Node.js using SCI.) is like babashka but for
Node.js. It provides a way to write quick ad-hoc scripts for Node.js
without requiring any other tools than Node.js and npm itself. You get
access to the wide array of libraries in the Node.js ecosystem. Like
babashka, nbb starts fast, scripts are evaluated by SCI and it has
some common libraries built-in: promesa, reagent, js-interop. It comes
with nREPL support for interactive development. Typical use cases are
writing TUI apps, browser tests and small web apps using express. This
talk highlights some of the use cases and also discusses some of the
implementation details.

Michiel Borkent doesn’t really need introductions in our community. He
is the main author of clj-kondo, babashka, jet and so many other
Clojure tools. He can be found as @borkdude in various places on the
