Collaborate serverless-ly on ClojureScript: crepl is back

17 Apr 2020

crepl is a collaborative editor written in Clojure and ClojureScript. In the editor you can write and evaluate ClojureScript code. And you can work on the same code together, similar to Google Docs. crepl has been offline for quite some time as I did not have a place to deploy it to. Recently, I have been playing around with compiling Clojure with GraalVM's native-image and deploying on AWS Lambda. Because AWS Lambda works together with websockets via API Gateway the whole crepl infrastructure can be deployed in a serverless manner too!

Try out the serverless crepl here:crepl.thegeez.net

Two people working on the same ClojureScript code and seeing the same output.

As a reminder, here's a list of some of the features in crepl:

• Import code, solve 4Clojure problems and use reagent
• Atom sync, share code and state
• Run code continuously
• Talk about crepl at EuroClojure 2017
