figwheel.main template

A template generator that will produce a minimal ClojureScript project that includes figwheel.main tooling.

Abridged Usage Examples

Already an expert? Can't stand to read more information? Assuming you have lein or clj-new installed, you can use one of the following commands:

clj -X:new clj-new/create :template figwheel-main :name yourname/hello-world :args '["+npm-bundle","--reagent"]' # or --rum, --react or nothing

or

lein new figwheel-main hello-world.core -- +npm-bundle --reagent # or --rum, --react or nothing

Overview

The figwheel-main template is intended to get you up and running with a no-frills ClojureScript project initialized with the ClojureScript React framework of your choosing. It is intended to work equally well with Leiningen or clj-new.

Usage

Using clj-new

Make sure you have installed the Clojure CLI tools and are running the latest version.

Also, ensure you have installed clj-new as detailed here. The following creates a project subfolder "hello-world" and a project using "yourname" as root namespace:

clj -X:new clj-new/create :template figwheel-main :name yourname/hello-world :args '["--reagent"]'

Using lein

Make sure you have the latest version of Leiningen installed.

lein new figwheel-main hello-world.core -- --reagent

Options

Takes a name and possibly a single framework option with the form --framework and any number of attribute options of the form +attribute and produces a minimal ClojureScript project that includes Figwheel Main tooling

The initial name option is intended to be the name of your initial project namespace. Here are some examples of valid project names:

hello.core
my.group/dominate.world

The framework options are:

 --react   which adds a minimal React/Sablono application in core.cljs
 --reagent which adds a minimal Reagent application in core.cljs
 --rum     which adds a minimal Rum application in core.cljs

The attribute options are:

 +npm-bundle  which sets up a build that utilizes npm modules
 +deps        which generates a deps.edn (a default when used with clj-new)
 +lein        which generates a project.clj (a default when used with lein)
 +bare-index  which generates an index without any annoyingly helpful content

Only one framework option can be specified at a time. If no framework option is specified, nothing but a print statment is added to the generated ClojureScript code.

Examples:

lein new figwheel-main hello-world.core -- +deps +npm-bundle --react

clj -X:new create :template figwheel-main :name yourname/hello-world :args '["+bare-index","+lein","--react"]'

Compiling the generated project

When using +npm-bundle you must run npm install before building your project

With a CLI tools project

To get an interactive development environment change into the project root (the directory just created) and execute:

clojure -M:fig:build

After the compilation process is complete, and a browser has popped open 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:

cljs.user=> (js/alert "Am I connected?")

and you should see an alert in the browser window.

You can also supply arguments to figwheel.main like so (this is equivalent to clojure -A:fig:build above):

clojure -A:fig -m figwheel.main -b dev -r

To clean all compiled files:

rm -rf target/public

To create a production build:

rm -rf target/public
clojure -A:fig:min

With Leiningen based project

To get an interactive development environment change into the project root (the directory just created) and execute:

lein fig:build

After the compilation process is complete, and a browser has popped open 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:

cljs.user=> (js/alert "Am I connected?")

and you should see an alert in the browser window.

You can also supply arguments to figwheel.main like so:

lein fig -- -b dev -r

To clean all compiled files:

lein clean

To create a production build:

lein clean
lein fig:min

Testing

Your initial tests are in the test directory. You will have tests that are updated live with each file change if you open a tab to http://localhost:9500/figwheel-extra-main/auto-testing

You can run your tests from the command line with:

clj -A:fig:test

or with lein:

lein fig:test
