endgame

endgame

A tiny module for ensuring uncaught exceptions are handled in Node.js.

Usage

Basic

Simply require and invoke.

// failed.js
var endgame = require('endgame');
 
endgame();
 
throw new Error('y u no work?');
 
// Thu, 09 Jan 2014 20:03:18 GMT uncaughtException y u no work?
// Error: y u no work?
//    at Object._onImmediate (/Users/me/src/git/myapp/failed.js:7:0)
//    at processImmediate [as _immediateCallback] (timers.js:330:15)

Undo

If an uncaughtException handler has already been registered, endgame becomes a noop. If an uncaughtException handler is registered after endgame has been invoked, endgame's default handler is automatically removed in favor of the newly registered handler.

endgame also returns a function that can be invoked to undo endgame's behavior.

// undo.js
var endgame = require('endgame'),
    undo = endgame();
 
// do stuff and decide to revert `endgame` changes
 
undo();

Custom handler

// custom.js
var endgame, undo;
 
endgame = require('endgame');
undo = endgame(function (err) {
    console.error(err.message);
    process.exit(1);
});
 
// ...
 
// implicit endgame undo
process.on('uncaughtException', function (err) {
    console.error(JSON.stringify(err)));
    process.exit(1);
});
 
// or `undo();`
