SpookyJS makes it possible to drive CasperJS suites from Node.js. At a high level, Spooky accomplishes this by spawning Casper as a child process and controlling it via RPC.
SpookyJS makes it possible to drive CasperJS suites from Node.js. At a high level, Spooky accomplishes this by spawning Casper as a child process and controlling it via RPC.
Specifically, each Spooky instance spawns a child Casper process that runs a bootstrap script. The bootstrap script sets up a JSON-RPC server that listens for commands from the parent Spooky instance over a transport (either HTTP or stdin). The script also sets up a JSON-RPC client that sends events to the parent Spooky instance via stdout.
