Watchdog node module

Kills the current process when another process is no longer running. This helps when the JavaScript event loop might be busy and never recovering e.g. an accidental while true loop.

This is implemented by launching a separate thread from C++ which periodically checks if the given process is still running. Typically, one would watch the parent process id. The watched process is checked every 1s and if it is no longer running, the current process will exit after 6 seconds with the exit code 87.

Installing

npm install native-watchdog

Using

var watchdog = require('native-watchdog');

watchdog.start(pid);

Developing

  • npm install -g node-gyp
  • node-gyp configure
  • node-gyp build (for debugging use node-gyp build --debug)
  • npm test (for debugging change index.js to load the node module from the Debug folder and press F5)
