A simple queue executing async functions linearly with pause/resume
npm install async-fun-queue
The most common use case:
var queue = new AsyncQueue([1, 2, 3], function (job, done) {
collection.push(job);
// simulate async
setTimeout(function () {
done();
}, 100);
});
queue.on('jobStart', function (job) {
// job begin to run
});
queue.on('jobDone', function (job) {
// job is done
});
queue.on('end', function () {
// all jobs are done
});
queue.run();A more complicated use case, with pause and resume method to controll the execution process:
var queue = new AsyncQueue([1, 2, 3], function (job, done) {
setTimeout(function () {
done();
if (job === 2) {
queue.pause();
setTimeout(function () {
queue.resume();
}, 100);
}
}, 100);
});
queue.on('pause', function () {
// queue is paused
});
queue.on('resume', function () {
// queue is resumed
});
queue.run();
