This below code just for dev demo, don't use it on production env: ```js 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`: ```js graceful({ servers: [server1, server2, restapi], killTimeout: '15s', }); ``` If you are using [pm](https://github.com/aleafs/pm), you can follow the [graceful_exit with pm demo](https://github.com/aleafs/pm/tree/master/demo/graceful_exit). ## Contributors |[
