properties

property type default description
animation-duration Number 1000 The duration of the animation.
animation-easing String 'ease' The easing of the animation.
animation-overlap Number 1 The overlap of the animation. Set the value to 1 to animate words all at once. Set the value to 0 to animate words one by one. The value 5 has the same effect as the value 1/5.
color [String, Function] 'Black' The default color for each word.
create-canvas Function * Creates a new Canvas instance.
create-worker Function * Creates a new Worker instance.
enter-animation [Object, String] * The enter animation.
font-family [String, Function] 'serif' The default font family for each word.
font-size-ratio Number 0 The font size ratio between the words. For example, if the value is 5, then the largest word will be 5 times larger than the smallest one. The value 5 has the same effect as the value 1/5.
font-style [String, Function] 'normal' The default font style for each word.
font-variant [String, Function] 'normal' The default font variant for each word.
font-weight [String, Function] 'normal' The default font weight for each word.
leave-animation [Object, String] * The leave animation.
load-font Function * Loads the font.
rotation-unit [String, Function] 'turn' The default rotation unit for each word. Possible values are 'turn', 'deg' and 'rad'.
rotation [Number, Function] 0 The default rotation for each word.
spacing Number 0 The spacing between the words. The value is relative to the font size.
text [String, Function] '' The default text for each word.
weight [Number, Function] 1 The default weight for each word.
words Array [] The words to place into the cloud. A value of the array could be either an object, an array or a string.
If the value is an object, it will be resolved to {text, weight, rotation, rotationUnit, fontFamily, fontStyle, fontVariant, fontWeight, color}.
If the value is an array, it will be resolved to [text, weight].
If the value is a string, it will be resolved to text.

let enterAnimation = {opacity: 0};
let leaveAnimation = {opacity: 0};

Make more complex animations.

let enterAnimation = {
  opacity: 0,
  transform: 'scale3d(0.3,0.3,0.3)'
};

Use classes for CSS animations.

let enterAnimation = 'animated bounceIn';
let leaveAnimation = 'animated hinge';

let createCanvas = function() {
  return document.createElement('canvas');
};

let loadFont = function(fontFamily, fontStyle, fontWeight, text) {
  return document.fonts.load([fontStyle, fontWeight, '1px', fontFamily].join(' '), text);
};

Provide custom loadFont function to support older browsers.

import FontFaceObserver from 'fontfaceobserver';

let loadFont = function(family, style, weight, text) {
  return (new FontFaceObserver(family, {style, weight})).load(text);
};

let createWorker = function(code) {
  return new Worker(URL.createObjectURL(new Blob([code])));
};

events

event description
update:progress The current progress of the cloud words computation.

todo

  • An option to customize the animation order of the cloud words by weight, font size and distance from center.
  • An option to privide an array of colors to colorize the cloud words by weight, font size and distance from center.
  • Prevent the recomputing of cloud words when changing color only.
  • An option to switch between canvas and dom renderer.
  • Speed up the computing of cloud words and improve the placing by reducing the image pixels.
