react-best-gradient-color-picker

react-best-gradient-color-picker

• Customizable, easy to use color and gradient picker for React.js
• Simply pass in an rgba or css gradient string as value and an onChange handler
• UI will default to solid or gradient based on the value string it receives
• You can customize the UI by hiding the various elements and updating value (see manual control below).

Install

npm install react-best-gradient-color-picker

Example

import React from 'react'
import ColorPicker from 'react-best-gradient-color-picker'

function MyApp() {
  const [color, setColor] = useState('rgba(255,255,255,1');

  return <ColorPicker value={color} onChange={setColor} />
}

Props

Name	Type	Default	Description
value	string	'rgba(175, 51, 242, 1)'	The starting color
hideInputs	boolean	false	(optional) hide the hex and rgba inputs
hidePresets	boolean	false	(optional) hide the preset color options
hideControls	boolean	false	(optional) hide the solid/gradient and gradient options

API

Name	Description
onChange	A function to update color value

Manual Control - Customizing UI

The state of the picker is determined by parsing the value string. You can update props like colorType (solid/gradient), gradientType (linear/radial), gradientDegrees, hex, rgba, opacity and hue simply by updating the value you are passing into the component. Let's say you want to change the colorType from gradient to solid:

import React from 'react'
import ColorPicker from 'react-best-gradient-color-picker'

function MyApp() {
  const [color, setColor] = useState('linear-gradient(90deg, rgba(96,93,93,1) 0%, rgba(255,255,255,1) 100%)');
  
  const setSolid = () => {
    setColor('rgba(255,255,255,1)') //color could be any rgba value
  }

  return(
    <div>
      <button onClick={setSolid}>Solid</button>
      <ColorPicker value={color} onChange={setColor} />
    </div>
   )
}

The same can be done in inverse to change colorType from solid to gradient:

  const setGradient = () => {
    setColor('linear-gradient(90deg, rgba(96,93,93,1) 0%, rgba(255,255,255,1) 100%)')
  }

Example toggling gradientType

  const setLinear = () => {
    setColor('linear-gradient(90deg, rgba(96,93,93,1) 0%, rgba(255,255,255,1) 100%)')
  }
  
  const setRadial = () => {
    setColor('radial-gradient(circle, rgba(96,93,93,1) 0%, rgba(255,255,255,1) 100%)')
  }

Custom linear-gradient degrees input

import React from 'react'
import ColorPicker from 'react-best-gradient-color-picker'

function MyApp() {
  const [color, setColor] = useState('linear-gradient(90deg, rgba(96,93,93,1) 0%, rgba(255,255,255,1) 100%)');
  const degrees = parseInt(value?.split(',')[0]?.split('(')[1])
  
  const handleDegrees = (val) => {
    let num = parseInt(val)
    let nans = isNaN(num) ? 0 : num
    let min = Math.max(nans, 0)
    let max = Math.min(min, 360)
    const remaining = value.split(/,(.+)/)[1]
    setColor(`linear-gradient(${max}deg, ${remaining}`)
  }

  return(
    <div>
      <input value={degrees} onChange={(e) => handleDegrees(e.target.value)} />
      <ColorPicker value={color} onChange={setColor} />
    </div>
   )
}
