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