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.
+bundle Generates a project with 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.
