Package Exports

cljs-canvas-backgrounds

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cljs-canvas-backgrounds) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cljs-canvas-backgrounds

Geometric repeating patterns for the HTML5 Canvas, written in ClojureScript.

They use Fabric.js but are otherwise framework agnostic, so can be easily included in any JavaScript project.

Usage

npm install cljs-canvas-backgrounds --save

Load the script at resources/public/js/compiled/cljs_canvas_backgrounds.js in your project.

This will give you a global cljs_canvas_backgrounds object, with the backgrounds as properties. Each has a draw function which you need to call, passing an options object, containing at least the id of your canvas element.

So, to initialize the checkerboard background:

cljs_canvas_backgrounds.checkerboard.draw({ id: "my-canvas-id" });

Replace the name to use a different background.

Other options

Background	`colors`	`size`	`spacing`	`width`	`height`
`checkerboard`	Array of strings, max. 2	Number (size of squares)
`polkadot`	Array of strings, max. 2	Number (size of dots)	Number (space between dots)
`mosaic`	Array of strings, no max.			Number (width of triangles)	Number (height of triangles)

Running locally

Make sure you have Leiningen installed.

To get an interactive development environment, run:

lein figwheel

and open your browser at localhost:3449. This will auto compile and send all changes to the browser without the need to reload. After the compilation process is complete, you will get a Browser Connected REPL. An easy way to try it 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.
