SVG rendering with PhantomJS. https://npmjs.org/package/svghost

Need prerendered SVG, like graphs in emails? SVGhost is for you! Easily integrated into your pipeline, it's compatible with major projects and services such as D3 and AWS. For example:

var svg = d3.select('body')
  .append('svg')
  .attr('width', 100)
  .attr('height', 100);

...

svghost(svg.node().outerHTML, {
    width: svg.attr('width')
  , height: svg.attr('height')
}, function (err, img) {
  if (err) ...
  
  new AWS.S3().putObject({
      ...
    , Body: img
  }, ...);
});

svghost(svg, options, next)

1. svg: String, XML document with an <svg> root.
2. options: Object.

• width: Number, required.
• height: Number, required.
• format: String, optional. png (default), gif, or jpeg.

3. next(err, buffer): Function, called with the error (if any) and the rendered image Buffer (if successful).

svghost.getPhantom(next)
Returns the PhantomJS process (err, proc), starting it if necessary. Mostly useful for preloading PhantomJS, but you can also use the process normally.

svghost.setPhantom(proc)
Sets the PhantomJS process. Only useful if you have custom settings or a custom version or an otherwise previously existing process you'd like to use for rendering.

svghost.delPhantom()
Stops the PhantomJS process. Useful for cleaning up if you won't be using svghost for a while.
