Process only 1 job using queue.process

Created by: cbjuan

Hi

Rather than an issue, this is a question about Bull. I'm coding a queues system where I don't need to process the queue in a continuous way (like it does queue.process()) but I need retrieve only one job each time I want (instead of processing every job available).

I tried to do this using process by this way:

const consumeJob = function(queue) {
  return new Promise(
    function(resolve, reject){
          queue.isReady().then(() =>{
            queue.process(function(job){ 
              queue.close();
              resolve(job);
            });
          })
          .catch(function(error){
            reject(error);
          });
    }
  );
};

In this case, using queue.close() I destroy the Redis connection, so if I want to retrieve other job (or continue operating using Bull) without reinitiating the script (or Node server) I get the error Error: Connection is closed. Knowing that, I would like to ask:

• If there is another way of obtaining only 1 (or N) job(s) using the queue.process method.
• Is it possible to reconnect Redis after the queue.close() to continue using bull in other functions and parts of my code?

Thanks in advance
