Server-side Render

Spritejs (>= 1.15.0) can render sprites' canvas on server-side. Depend on node-canvas.

sudo apt-get install libcairo2-dev libjpeg-dev libpango1.0-dev librsvg2-dev libgif-dev build-essential g++
npm install canvas@next
const fs = require('fs')

const {Scene, Label} = require('spritejs')
const scene = new Scene('#test', 800, 600)

const bglayer = scene.layer('bg', {handleEvent: false})

const text = new Label('Hello Sprite!')

text.attr({
  anchor: [0.5, 0.5],
  pos: [400, 300],
  font: '46px Arial',
  color: 'blue',
  bgcolor: 'white',
  textAlign: 'center',
})

bglayer.append(text)

;(async function () {
  const canvas = await scene.snapshot()
  fs.writeFileSync('snap.png', canvas.toBuffer())
}())
