queue:work command to start them but these are considered long-lived processes and store the booted application state in memory. So this means after you make any code changes you’ll need to restart them that way they have a fresh state.
When developing locally this can get burdensome, and if you are like me you might forget to restart them. Leaving you scratching your head why the changes you made aren’t working. I’ve personally wasted a lot of time doing this and I think it’s something easy to forget. To make this a problem of the past Laravel provides a

Both commands are equivalent as well.
1php artisan queue:work --queue=high,default
