renderToMarkup(renderer)

This method should only be used on the server.

Renders all cached styles grouped CSS strings and returns a valid HTML markup with <style> elements. The elements are grouped and sorted in the following order:

  1. Fonts
  2. Static Styles
  3. Keyframes
  4. Rules
  5. Support Rules
  6. Media Query Rules
  7. Support & Media Query Rules

The DOM renderer is able to rehydrate its cache from the markup in order to skip initial rendering.

Returns

(string): Single concatenated HTML markup string containing required <style> elements.

Example

import { renderToMarkup } from 'fela-dom'
import { createRenderer } from 'fela'

const renderer = createRenderer()

const rule = ({ fontSize }) => ({
  fontSize: fontSize,
  color: 'blue',
  '@supports (display: flex)': {
    color: 'green'
  },
  '@media (min-width: 300px)': {
    color: 'red'
  }
})

renderer.renderStatic('html,body{box-sizing:border-box;margin:0}').
renderer.renderRule(rule, { fontSize: '12px' })

const markup = renderToMarkup(renderer)

The following markup would be returned:

<style type="text/css" data-fela-type="STATIC">html,body{box-sizing:border-box;margin:0}</style>
<style type="text/css" data-fela-type="RULE">.a{font-size:12px}.b{color:blue}</style>
<style type="text/css" data-fela-type="RULE" data-fela-support>.c{color:green}</style>
<style type="text/css" data-fela-type="RULE" media="(min-width: 300px)">.d{color:red}</style>
