Watch explicit flow stay ordered.

This page imports the published queue.js directly. Run it, pause the release gate, resume, or clear pending work.

What you are seeing

Each task owns the amber active state for a short delay, then calls this.next(). Pause closes the stop gate; clear removes only tasks that have not started.

Copy a shape

Three focused recipes.

Use the queue for sequencing, manual batches, or connection-gated work. The API stays the same.

Sequential

Wait for a callback

queue.add(function(){
    save(data,()=>this.next());
});

Batch

Start manually

queue.autoRun=false;
queue.add(one,two,three);
queue.next();

Gate

Wait for readiness

queue.stop=true;
queue.add(send);
ready.then(()=>{
    queue.stop=false;
    queue.next();
});
