cluster-service/lib/stop.js

Turns your single process code into a fault-resilient multi-process service with built-in REST & CLI support

var cservice = require("../cluster-service");

module.exports = exports = stop;

function stop(timeout, cb) {
  if (cservice.locals.state === 0) {
    if (cb) cb(null, "Not running");
    return;
  }

  if (cservice.workers.length > 0) { // issue shutdown
    cservice.trigger("shutdown", function() {
      handleWorkersExited(cb);
    }, "all", timeout);
  } else { // gracefully shutdown
    handleWorkersExited(cb);
  }
}

function handleWorkersExited(cb) {
  if (cb) cb(null, "Shutting down...");
  require("./http-server").close();
  cservice.locals.state = 0;
  if (cservice.options.cli === true) {
    process.exit(1);
  }
