raise

Send a signal to the current process (see raise(3))

Installation

npm install raise

Usage

var raise = require('raise');
 
// unceremoniously end this process
raise('SIGKILL');

Uses

This can be useful for debugging purposes. A lot of times I've used DTrace to pause a process when it hits a certain code path so I can inspect its memory. With this module, you can simply add a raise statement where you would like to send a signal to the process.

var raise = require('raise');
 
var a = [];
for (var i = 0; i < 100; i++) {
  a.push(a); // obvious bug
 
  // say you thought this function was a problem, but you couldn't identify why,
  // pause the process on the 10th iteration to coredump and inspect the memory
  if (i === 10) raise('SIGSTOP');
}
