Easily generate color gradients with an unlimited number of color stops and steps.
$ npm install tinygradient The gradient can be generated using RGB or HSV interpolation. HSV usually produces brighter colors.
The tinygradient constructor takes a list or an array of colors stops.
// using varargs const gradient = tinygradient('red', 'green', 'blue'); // using array const gradient = tinygradient([ '#ff0000', '#00ff00', '#0000ff' ]);The colors are parsed with TinyColor, multiple formats are accepted.
const gradient = tinygradient([ tinycolor('#ff0000'), // tinycolor object {r: 0, g: 255, b: 0}, // RGB object {h: 240, s: 1, v: 1, a: 1}, // HSVa object 'rgb(120, 120, 0)', // RGB CSS string 'gold' // named color ]);You can also specify the position of each color stop (between 0 and 1). If no position is specified, stops are distributed equidistantly.
const gradient = tinygradient([ {color: '#d8e0de', pos: 0}, {color: '#255B53', pos: 0.8}, {color: '#000000', pos: 1} ]);Each method takes at least the number of desired steps.
The generated gradients might have one more step in certain conditions.
// RGB interpolation const colorsRgb = gradient.rgb(9);
// HSV clockwise interpolation const colorsHsv = gradient.hsv(9);
// HSV counter-clockwise interpolation const colorsHsv = gradient.hsv(9, true);
There are also two methods which will automatically choose between clockwise and counter-clockwise.
// HSV interpolation using shortest arc between colors const colorsHsv = gradient.hsv(9, 'short'); // HSV interpolation using longest arc between colors const colorsHsv = gradient.hsv(9, 'long');Each method returns an array of TinyColor objects, see available methods.
The css method will output a valid W3C string (without vendors prefix) to use with background-image CSS property.
// linear gradient to right (default) const gradientStr = gradient.css(); // radial gradient ellipse at top left const gradientStr = gradient.css('radial', 'farthest-corner ellipse at top left');Returns a single TinyColor object from a defined position in the gradient (from 0 to 1).
// with RGB interpolation colorAt55Percent = gradient.rgbAt(0.55); // with HSV interpolation colorAt55Percent = gradient.hsvAt(0.55);Returns a new instance of TinyGradient with reversed colors.
const reversedGradient = gradient.reverse();Returns a new instance of TinyGradient with looped colors.
const loopedGradient = gradient.loop();I is possible to define stops with the pos property only and no color. This allows to define the position of the mid-point between the previous and the next stop.
const gradient = tinygradient([ {color: 'black', pos: 0}, {pos: 0.8}, // #808080 will be at 80% instead of 50% {color: 'white', pos: 1} ]);This library is available under the MIT license.
