Use canvas2svg for

easy vector outputs from canvas drawings

const size = 1000

const canvas = document.createElement('canvas')
canvas.width = size
canvas.height = size
document.body.appendChild(canvas)
const context = canvas.getContext('2d')

context.strokeStyle = '#fff'
context.lineWidth = 5
context.lineCap = 'round'

const u = size / 20
context.beginPath()
for (let i = 0; i < 100; i++) {
  const x = i%10
  const y = Math.floor(i/10)
  const rotations = (i%3 === 0 && 1) + (i%4 === 0 && 2)
  context.save()
  context.translate(u+x*u*2, u+y*u*2)
  context.rotate(rotations * Math.PI / 2)
  context.moveTo(-u, u)
  context.quadraticCurveTo(-u, -u, u, -u)
  context.restore()
}
context.stroke()
const size = 1000

import saveAs from 'file-saver'
import C2S from 'canvas2svg'


const context = new C2S(size, size)

context.strokeStyle = '#fff'
context.lineWidth = 5
context.lineCap = 'round'

const u = size / 20
context.beginPath()
for (let i = 0; i < 100; i++) {
  const x = i%10
  const y = Math.floor(i/10)
  rotations = (i%3 === 0 && 1) + (i%4 === 0 && 2)
  context.save()
  context.translate(u+x*u*2, u+y*u*2)
  context.rotate(rotations * Math.PI / 2)
  context.moveTo(-u, u)
  context.quadraticCurveTo(-u, -u, u, -u)
  context.restore()
}
context.stroke()

const blob = new Blob([context.getSerializedSvg()], {
  type: 'text/plain',
})
saveAs(blob, 'pattern.svg')

FFConf 2019 - Taking The Web Off The Screen

The rise of generative art has brought a whole new wave of creativity to the web; this talk is about the myriad of ways we can use all that coding knowledge to make cool art in the physical realm.
