Inter Process Communication

There are multiple ways to handle inter-process communication between PhantomJS and other processes.

File I/O

• files
• sockets
• named pipes

HTTP

• outgoing HTTP requests (to other processes/services)

  • GET/POST data to a server endpoint
  • GET/POST data to a server endpoint, parse resulting JSON/XML/HTML/etc.

• incoming HTTP requests (server)

• route PhantomJS traffic through an HTTPS proxy like mitmproxy/libmproxy

Websockets inside a WebPage context

• hixie-76 websockets only
• PhantomJS 2.x will eventually get a WebKit upgrade that has RFC 6455 websockets.

stdin, stdout, and stderr

See the stdin-stdout-stderr.js example script for details.
