“Invoker: functions are all you need”
Invoker is a zero config CLI, HTTP, and REPL interface for Clojure.
Commands will automatically connect to an existing nREPL server if available using .nrepl-port. The nvk http and nvk repl commands start a nREPL server that can be connected to.
Invoker aims to make the following usecases easy:
- making a simple webapp from scratch, possibly with Datomic
- running functions and inspecting atoms inside an existing process
- running targetted tests with reloaded code
- allowing agents to interact with your clojure process
- adding dependencies and reloading code without restarting the process
