CIDER’s Architecture
Heart of the Orchard
nREPL
Created especially for REPL-powered tooling
Extremely flexible
Transports•bencode (default)•tty (built-in)•http(s) (via Drawbridge)•transit (via Fastlane)•EDN (coming soon)
Piggieback
cider-nrepl
Middleware for interactiveprogramming environments
Thin wrapper around (many)nREPL-agnostic libraries
