Use PhantomJS to render PDF in Rails

Avoid disk IO

If you're deploying your app to somewhere where you can't be sure to have reliable disk read/write access, the normal strategy of writing to a temp-file doesn't work. Instead we can open a pipe to the Phantom.js process, and then pass in the HTML via stdin, and then have the rasterize.js script write out the resulting PDF to stdout, which we can then capture. Any log messages from the Phantom.js process can be passed via stderr if we want.
