times-up

Wrap asynchronous calls with a timeout checker to prevent them from hanging indefinitely

Example

var timesUp = require('times-up');

function asyncFunc(callback) {
  setTimeout(function () {
  	console.log('Some process in the future.');
  	callback(null, 'done', 42);
  }, 2000);
}

asyncFunc(timesUp('asyncFunc', 1000, function (err, res0, res1) {
  if (err) {
  	throw err;
  } else {
  	console.log('Res: '+res0+', '+res1);
  }
}));

Outputs

$ node app.js 
/tmp/bar/app.js:12
  	throw err;
  	      ^
Error: Method asyncFunc timed out (1000ms)
    at null._onTimeout (/tmp/bar/node_modules/times-up/times-up.js:32:18)
    at Timer.listOnTimeout (timers.js:110:15)

Because times-up timeout is set to 1000ms and asyncFunc() waits for 2000ms
