exit Build Status

A replacement for process.exit that ensures stdio are fully drained before exiting.

To make a long story short, if process.exit is called on Windows, script output is often truncated when pipe-redirecting stdout or stderr. This module attempts to work around this issue by waiting until those streams have been completely drained before actually calling process.exit.

See Node.js issue #3584 for further reference.

Tested in OS X 10.8, Windows 7 on Node.js 0.8.25 and 0.10.18.

Based on some code by @vladikoff.

Getting Started

Install the module with: npm install exit

var exit = require('exit'); // These lines should appear in the output, EVEN ON WINDOWS. console.log("omg"); console.error("yay"); // process.exit(5); exit(5); // These lines shouldn't appear in the output. console.log("wtf"); console.error("bro");

Don't believe me? Try it for yourself.

In Windows, clone the repo and cd to the test\fixtures directory. The only difference between log.js and log-broken.js is that the former uses exit while the latter calls process.exit directly.

This test was done using cmd.exe, but you can see the same results using | grep "std" in either PowerShell or git-bash.

C:\node-exit\test\fixtures>node log.js 0 10 stdout stderr 2>&1 | find "std" stdout 0 stderr 0 stdout 1 stderr 1 stdout 2 stderr 2 stdout 3 stderr 3 stdout 4 stderr 4 stdout 5 stderr 5 stdout 6 stderr 6 stdout 7 stderr 7 stdout 8 stderr 8 stdout 9 stderr 9 C:\node-exit\test\fixtures>node log-broken.js 0 10 stdout stderr 2>&1 | find "std" C:\node-exit\test\fixtures>


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
