PupTex

Using Puppeteer(Headless Chrome) to render math:

• 2x faster than mathjax-node
• Configurable concurrent limit
• Renders CJK characters correctly

Usage

Node

const puptex = require('puptex')

;(async () => {
  puptex.config({
    concurrency: 2,
    mathJax: {},
  })
  await puptex.launch()
  const data = await puptex.renderMath('E=mc^2')
  // data => {errors: [], svg: '<svg .../>', mml: '', widht: '', height: '', ...}
  puptex.close()
})()
