A concise guide to picking :none, :simple or :advanced for ClojureScript production builds.
Learn how to build reactive user interfaces in ClojureScript using Reagent atoms and Shadow-CLJS for efficient state management and hot-reloading.
Use core.async go blocks to turn callback-heavy ClojureScript UI code into sequential logic without blocking the browser event loop.
Configure ClojureScript code splitting with Closure Compiler modules using cljs.main or shadow-cljs. Define a base module, add feature entry points, verify output sizes, and implement runtime loading with error recovery.
Practical guidance for calling JavaScript from ClojureScript using the js/ prefix and converting data with clj->js.
Shrink your ClojureScript bundle by enabling :advanced compiler optimizations and adding proper externs for external libraries like lodash. Follow a concrete example, verify runtime integrity, and understand the trade‑offs.
Learn how to enable genuine dead‑code elimination in ClojureScript using Shadow‑CLJS with :optimizations :advanced, verify the bundle size, and avoid common interop pitfalls.
Shadow-CLJS makes npm a first-class ClojureScript dependency with automatic externs and incremental builds, speeding UI feedback while requiring care with advanced compilation.
Guidance on picking shadow-cljs or the official ClojureScript compiler for a web app, covering npm integration, REPL workflow, and build trade‑offs.
