lein-figwheel

Automatically reloads ClojureScript, CSS, and JavaScript on save with a stable websocket connection that persists across browser sessions and OS sleeps, as highlighted in the 'Robust connection' feature.

Launches a ClojureScript REPL into the running application with live compilation awareness and special control functions like start-autobuild, providing interactive programming without manual steps.

Calculates and reloads only necessary files to maintain client environment stability, respecting dependencies and avoiding code with warnings unless configured otherwise.

Includes a non-intrusive heads-up display for compilation status and errors with click-to-open editor links, plus descriptive error reporting for both code and configuration.
