shadow-cljs is a ClojureScript build tool designed with simplicity and modern JavaScript interoperability in mind. Distributed via npm, it handles compilation, hot-reloading, module targets (ESM, Node, Browser), and tight integration with JS tooling. Creating your project can be done quickly using the npx create-cljs-project utility. npx is part of npm and lets us run utility scripts quickly without worrying about installing them first. The installer will create a basic project scaffold and install the latest version of shadow-cljs in the project. When building actual projects we need to configure the build first and create at least one source file.

Features

  • All-in-one ClojureScript compiler with minimal configuration required
  • Supports watch mode, hot code reloading, and REPL-driven development
  • Tight integration with npm, JS modules, and the modern JavaScript ecosystem
  • Provides static file server support, live REPLs, and development convenience tooling
  • Works seamlessly with editors—e.g., CIDER, Calva—to launch and connect to builds
  • Supports targets such as ES Modules, enabling use in browsers, Deno, Node, etc.
