Setting up Arena as a node module

[MrNghia123]

Hi,

Thanks for the package.

I have an express app as the frontend to mange a backend system making use of bull queue to process files download/upload
I want to set up arena to use in the current express app to share all the security and other facilities.
I followed the guides here https://github.com/bee-queue/arena#running-arena-as-a-node-module.
2 issues:
1/ Asynchronously build the queues configuration and inject to Arena
Although there is a guide which seem to do similar:
https://mixmax.com/blog/bull-queue-aws-autodiscovery
However the guide there just ends up at the async function which return the queues, so I don't know how would that be injected to Arena later on.
2/ Arena dashboard is not filled with data
I attempted to hardcode queues configuration :
const arenaConfig = Arena({
queues: [
{
// Name of the bull queue, this name must match up exactly with what you've defined in bull.
name: "download",

  // Hostname or queue prefix, you can put whatever you want.
  hostId: "MyAwesomeQueues",

  // Redis auth.
  redis: {
    port: 6379,
    host:  '127.0.0.1',
  },
},

],
},
{
// Make the arena dashboard become available at {my-site.com}/arena.
// basePath: '/arena',
useCdn: true,
// Let express handle the listening.
disableListen: true
});

// Make arena's resources (js/css deps) available at the base app route
router.use('/arena', arenaConfig);

The dashboard now show up. However it is just empty with only the "download" queue link show up, but just show "not found" when clicked on.
