childprocess-queue

npm Version

Use childprocess module freely while limiting the amount of concurrent processes

Includes:

  • Limit how many processes are running at the same time. Additional processes will be queued.
  • Supports fork, spawn, exec, execFile with the usual signature, with exception of returning an id and not a ChildProcess.
  • Add an onCreate callback to the options that you pass, to get a notification when the process was created. One argument will be passed back, containing the ChildProcess instance.
  • Call newQueue to receive a separate queue that you can use like the main ChildProcessQueue object.
  • Call setMaxProcesses to set the maximum concurrent processes.
  • Call getMaxProcesses to get the maximum concurrent processes (defaults to 5).
  • Call getCurrentProcessCount to get the number of currently running processes.
  • Call getCurrentProcesses to get an array of the currently running processes.
  • Call getCurrentQueueSize to get the number of processes waiting in the queue.
  • Call removeFromQueue with an id to remove a pending process from the queue.

Installation:

npm install --save childprocess-queue
