Canvas Particle Network

NPM version Bower version NPM dependencies NPM devDependencies NPM total downloads

Overview

In this experiment, I set out to build a simple, sexy, interactive, and animated particle network using Canvas and JavaScript. Fully plug n' play, modular (via Browserify and WebPack), and customisable, just drop it in any webpage.

See it live on CodePen

Alternatively, fork the repo and open

demo.html
to give it a whirl; the minified version comes in at just under a cheeky 4KB uncompressed, and 1.3KB when gzipped!

Usage

The plugin is available as

canvas-particle-network
via Bower or NPM. Alternatively, you can simply clone this repository.

For a barebones implementation, simply add a HTML

div
to your body. You may specify its dimensions via CSS/JavaScript without any issues, as well as specify multiple instances. Then, simply add the JavaScript file to the end of your
body
and create a
ParticleNetwork
instance using your canvas ID.
    

Additionally, a number of options are supported (see below). Simply append any of these options to your arguments on creation.

var options = {
    particleColor: '#fff',
    background: '#1a252f',
    interactive: true,
    speed: 'fast',
    density: 'medium'
};
var particleCanvas = new ParticleNetwork(document.getElementById('particle-canvas'), options);

Options

options.particleColor

Type:

String

Default:
#ffffff

Color of the particles. Must be a valid hexadecimal code.

options.background

Type:

String

Default:
#1a252f

Specifies a background color or image to the canvas. Must be a valid image URL (e.g.

img/demo-bg.jpg
) or hexadecimal code.

options.interactive

Type:

Boolean

Default:
true

Allow users to click on the canvas to create a new particle. Its velocity will depend on the specified speed (see below).

options.speed

Type:

String

Default:
medium

Velocity of the particles. Must be one of the following:

  • none
  • slow
  • medium
  • fast

options.density

Type:

String
or
Number

Default:
medium
(alias for
10000
)

Density of the particles. Actual amount depends on the canvas size, and is calculate by dividing the total canvas size by the density. The following values are accepted:

  • low
    (or
    20000
    )
  • medium
    (or
    10000
    )
  • high
    (or
    5000
    )
  • Any number

Please note that the higher the density, the more computationally intensive / slower each animation step becomes!
