Figma Squircle

Figma-flavored squircles for everyone

Disclaimer

This library is not an official product from the Figma team and does not guarantee to produce the same results as you would get in Figma.

What is this?

Figma has a great feature called corner smoothing, allowing you to create rounded shapes with a seamless continuous curve (squircles).

This library helps you bring those squircles to your apps.

Installation

npm install figma-squircle

Usage

import { getSvgPath } from 'figma-squircle'

const svgPath = getSvgPath({
  width: 200,
  height: 200,
  cornerRadius: 24, // defaults to 0
  cornerSmoothing: 0.8, // cornerSmoothing goes from 0 to 1
})

const svgPath = getSvgPath({
  width: 200,
  height: 200,
  cornerRadius: 24,
  cornerSmoothing: 0.8,
  // You can also adjust the radius of each corner individually
  topLeftCornerRadius: 48,
})

// svgPath can now be used to create SVG elements
function PinkSquircle() {
  return (
    <svg width="200" height="200" xmlns="http://www.w3.org/2000/svg">
      <path d={svgPath} fill="pink" />
    </svg>
  )
}

// Or with the clip-path CSS property
function ProfilePicture() {
  return (
    <div
      style={{
        width: 200,
        height: 200,
        clipPath: `path('${svgPath}')`,
      }}
    >
      ...
    </div>
  )
}

Preserve Smoothing

The larger the corner radius, the less space we have left to make a smooth transition from the straight line to the rounded corner. As a result, you might have noticed that the smoothing effect appears to be less pronounced as the radius gets bigger.

Try enabling preserveSmoothing if you're not happy with the generated shape.

const svgPath = getSvgPath({
  width: 200,
  height: 200,
  cornerRadius: 80,
  cornerSmoothing: 0.8,
  preserveSmoothing: true, // defaults to false
})

There's also a Figma plugin that utilizes this option.
