A Leinigen template to get started with Figwheel.

Make sure you have the latest version of leiningen installed.

lein new figwheel hello-world

--react     Adds a bare bones React app, including Sablono.
--reagent   Adds a bare bones Reagent app.
--rum       Adds a bare bones Rum app.
+no-bundle  Generates a project without npm and webpack support.

Include the options using -- to separate them from Leiningens options, like so

lein new figwheel hello-world -- --reagent

To get an interactive development environment run

npm install

and then

lein figwheel

from the project root directory.

Wait ... until the project finishes compiling and then ... open your browser at localhost:3449/index.html.

Figwheel will now be running and will auto compile and send all changes to the browser without the need to reload.

After the compilation process is complete, and you have loaded the compiled project in your browser you will get a ClojureScript REPL prompt that is connected to the browser.

An easy way to verify this is:

(js/alert "Am I connected?")

and you should see an alert in the browser window.

To clean all compiled files:

lein clean

To create a production build run:

lein do clean, cljsbuild once min

And open your browser in resources/public/index.html. You will not get live reloading, nor a REPL.

The generated project is compatible with Webpack and npm and you can add JavaScript dependencies via the normal npm install route.

Alternatively you can lauch Figwheel from the REPL.

If you run lein repl a Clojure REPL will launch.

From this REPL prompt you can run

user> (fig-start)

and this will launch figwheel but will not launch the ClojureScript REPL.

You can launch the Figwheel ClojureScript REPL like so:

user> (cljs-repl)

Please see dev/user.clj for more information.

Note: you should always run lein figwheel to verify that you have setup everything correctly.
