Choosing a ClojureScript Optimization Level for Production Builds
A concise guide to picking :none, :simple or :advanced for ClojureScript production builds.
Prevent Broken JavaScript Interop in ClojureScript Advanced Builds
Use externs files to protect external JavaScript names when compiling ClojureScript with :optimizations :advanced.
Managing Reactive UI State in ClojureScript with Reagent and Shadow-CLJS
Learn how to build reactive user interfaces in ClojureScript using Reagent atoms and Shadow-CLJS for efficient state management and hot-reloading.
Sequential Async UI Logic in ClojureScript with core.async
Use core.async go blocks to turn callback-heavy ClojureScript UI code into sequential logic without blocking the browser event loop.
Code Splitting in ClojureScript with Closure Compiler Modules
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.
ClojureScript Advanced Compilation: Dead Code Elimination and the Externs Trade-off
ClojureScript's :advanced compilation can shrink a Reagent app from 180 KB to 45 KB gzipped, but only if you describe every external JavaScript dependency in externs files. This post shows the size gains, the externs pitfall, and a practical CI profile strategy.
Adopting Reagent for Reactive UIs in ClojureScript
Reagent lets ClojureScript developers write React UI in Hiccup syntax, using atoms for reactive state and hot reloading via shadow‑cljs. This blog explains its benefits, shows a counter example, discusses performance trade‑offs, and gives a practical checklist to get started.
reactCreating and Validating JavaScript Objects in ClojureScript
Create plain JavaScript objects in ClojureScript with #js literals, read nested properties safely using goog.object, and isolate mutation at the interop boundary.
