Package Exports
- @melloware/coloris
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 (@melloware/coloris) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Getting Started
Basic usage
Download the latest version, and add the script and style to your page:
<link rel="stylesheet" href="coloris.min.css"/>
<script src="coloris.min.js"></script>
Then just add the data-coloris attribute to your input fields:
<input type="text" data-coloris>
That's it. All done!
NPM
You can also download the color picker from NPM
# using NPM
npm install @melloware/coloris
# using Yarn
yarn add @melloware/coloris
And then use it within a module environment, e.g. with browserify, rollup, webpack etc. In this case, you must initialize the color picker before its first use (which has several side-effects such as adding DOM elements):
import "@melloware/coloris/dist/coloris.css";
import Coloris from "@melloware/coloris";
Coloris.init();
Coloris({el: "#coloris"});
AMD
The color picker also works with AMD / require.js:
requirejs(['@melloware/coloris'], function (Coloris) {
Coloris.init();
Coloris({
el: "#coloris",
});
});
Options
Coloris({
// The default behavior is to append the color picker's dialog to the end of the document's
// body. but it is possible to append it to a custom parent instead. This is especially useful
// if the color fields are in a scrollable container and you want color picker' dialog to stay
// anchored to them. You will need to set the position of the container to relative or absolute.
parent: '.container',
// A custom selector to bind the color picker to. This must point to input fields.
el: '.color-field',
// The bound input fields are wrapped in a div that adds a thumbnail showing the current color
// and a button to open the color picker (for accessibility only). If you wish to keep your
// fields unaltered, set this to false, in which case you will lose the color thumbnail and
// the accessible button (not recommended).
wrap: true,
// Available themes: light, dark, large, large-dark, polaroid, polaroid-dark.
// More themes might be added in the future.
theme: 'light',
// The margin in pixels between the input fields and the color picker's dialog.
margin: 2,
// Set the preferred color string format:
// * hex: outputs #RRGGBB or #RRGGBBAA (default).
// * rgb: outputs rgb(R, G, B) or rgba(R, G, B, A).
// * hsl: outputs hsl(H, S, L) or hsla(H, S, L, A).
// * auto: guesses the format from the active input field. Defaults to hex if it fails.
// * mixed: outputs #RRGGBB when alpha is 1; otherwise rgba(R, G, B, A).
format: 'hex',
// Enable or disable alpha support.
// When disabled, it will strip the alpha value from the existing color value in all formats.
alpha: true,
// Show an optional clear button and set its label
clearButton: {
show: true,
label: 'Clear'
},
// An array of the desired color swatches to display. If omitted or the array is empty,
// the color swatches will be disabled.
swatches: [
'#264653',
'#2a9d8f',
'#e9c46a',
'rgb(244,162,97)',
'#e76f51',
'#d62828',
'navy',
'#07b',
'#0096c7',
'#00b4d880',
'rgba(0,119,182,0.8)',
]
});
Events
An "input" event is triggered on the bound input field whenever a new color is selected. A "change" event is triggered when the color picker is closed and if the color has changed since it was opened.
Closing the color picker
The color picker dialog can be closed by clicking anywhere on the page or by pressing the ESC on the keyboard. The later will also revert the color to its original value.
If you would like to close the dialog programmatically, you can do so by calling the close() method:
// Close the dialog
Coloris.close();
// Close the dialog and revert the color to its original value
Coloris.close(true);
TypeScript
This package includes TypeScript declarations. When you use it in a module environment, just import it:
import "@melloware/coloris/dist/coloris.css";
import Coloris from "@melloware/coloris";
Coloris.init();
Coloris({el: "#coloris"});
Coloris.close();
If you wish to write a global script file, use a triple slash reference:
/// <reference types="@melloware/coloris" />
Coloris({
el: "#coloris",
});
Building from source
Clone the git repo:
git clone git@github.com:melloware/Coloris.git
Enter the Coloris directory and install the development dependencies:
cd Coloris && npm install
Run the build script:
npm run build
The built version will be in the dist
directory in both minified and full copies.
Alternatively, you can start a gulp watch task to automatically build when the source files are modified:
npm run start
Publishing
Adjust the version in the package.json
if necessary, then
npm login
# This will run npm run build automatically
npm publish --access public
Then upload code to github, create tag & release.
