What’s the difference between contrib’s nREPL and this one?

See our history. Very simply put - this project is the continuation of the contrib project.

What’s the plural form of "middleware"?

The plural form of "middleware" is "middleware", not "middlewares".[1] While there’s some debate on whether its okay to write something like "a collection of middlewares", we’ve opted to stick to using "middleware" everywhere in both the codebase and the documentation.

Does nREPL support ClojureScript?

Yes, it does, although you’ll need additional middleware to enable the ClojureScript support (e.g. piggieback or shadow-cljs).

Does nREPL support ClojureCLR?

There is a separate implementation of nREPL for ClojureCLR: https://github.com/clojure/clr.tools.nrepl.

When is nREPL 1.0 going to be released?

nREPL was released on August 24, 2022. This completes the promise we made way back in 2018 to address most languishing problems and get nREPL in a great shape.

Future releases will focus on polishing the nREPL protocol and potentially adding some new features.

Are there any interesting nREPL extensions worth checking out?

Sure! See Extensions for details.
