Ladder (ladderlife.com) is written entirely Clojure(Script). We feel it was worth it - having a single language that can stretch from frontend to ETL code is pretty powerful. The fact that parallelism in Clojure is real (and not 16 separate processes) is pretty great too. Some of the downsides are: the slow startup time and fat(ish) JavaScript payloads because of the extra runtime libraries. The community can also be a bit unwelcoming of new ideas sometimes. If you’re thinking of migrating - especially if it’s just a rest API - just start with Ring (& maybe bidi for routing). It’s not really a framework - you can pick and choose what else fits into your stack well after that. Clojure libraries tend to be very stateless and end up composing surprisingly well. I think Fulcro is a bit more useful if you’re building a frontend from scratch with React. In terms of hiring - it’s very similar to a niche language. You get less folks that are specialists in Clojure like people are specialists in Node or Ruby. It’s also an easy to teach the language so you can bring most people up to speed in a month or so. Our hiring process favors generalists - and Clojure fits in well for that role. I don’t think specialists would have a good time with Clojure though - it’s not the kind of language that is easy to use as a means to an end.
