shadow-cljs-sass

A Leiningen template for a clojure deps project with shadow-cljs, sass and some tooling.

Usage

lein new shadow-cljs-sass my-project

Template readme

Minimal project giving a react, reagent and shadow-cljs setup ready to go.

Running

• Ensure you have a recent version of nodeJS installed. This was tested with node 12.8.0
• Install the clojure command line tools. on MacOS with homebrew this is usually as simple as brew install clojure.
• run npm install
• run make dev
• wait a bit
• server should be available on localhost:9966

Connecting to the build

By default, shadow-cljs will compile the build called :frontend, as referenced in the file shadow-cljs.edn

Once the process has booted up, it will provide an nrepl port to the local .shadow-cljs directory, along with other port information. You can also see which port the nrepl is listening on in the terminal - it looks like shadow-cljs - nREPL server started on port 59128.

Configure your nrepl as usual to connect to thiis port, and once connected, and a browser is open, you may connect to the live process in the browser with the command:

(shadow/repl :frontend)

verify that your connection is working with the command (js/alert "hi") and observe that an alert has been opened in your browser.

To drop out of the CLJS connection enter the keyword :cljs/quit into the repl and evaluate it. You will then be back in the JVM clojure process.

Static assets

index.html is provided and lives in the public folder. The referenced css/main.css will be built by the sass process. You can write pure CSS into the sass file, as sass syntax sits on top of baseline standard CSS.

JS assets will be compiled into this folder as well, but the compiled output should be ignored, like the compiled CSS.
