graceful

Graceful exit when uncaughtException emit, base on process.on('uncaughtException').

Why we should use this module

It's the best way to handle uncaughtException on current situations.

Install

$ npm install graceful

Usage

Please see connect_with_cluster example.

This below code just for dev demo, don't use it on production env:

var express = require('express');
var graceful = require('graceful');

var app = express()
.use()
.use(function(req, res){
  if (Math.random() > 0.5) {
    foo.bar();
  }
  setTimeout(function() {
    if (Math.random() > 0.5) {
      throw new Error('Asynchronous error from timeout');
    } else {
      res.end('Hello from Connect!');
    }
  }, 100);
  setTimeout(function() {
    if (Math.random() > 0.5) {
      throw new Error('Mock second error');
    }
  }, 200);
})
.use(function(err, req, res, next) {
  res.end(err.message);
});

var server = app.listen(1984);

graceful({
  servers: [server],
  killTimeout: '30s',
});

If you have multi servers on one process, you just add them to server:

graceful({
  servers: [server1, server2, restapi],
  killTimeout: '15s',
});

If you are using pm, you can follow the graceful_exit with pm demo.
