Moleculer-queues NPM

moleculer-queues

Redis-based queue for moleculerjs using Bull.

This package was created with the purpose of solving some problems with the original "moleculer-bull" package, with a new logic this module allows to run jobs manually using "methods" this to avoid "duplication of jobs when the service starts" , it also supports repetitive jobs just like "bull" does, each task is restarted every time the service stops thus avoiding task overload and "double-run"

The main idea of this package is to allow it to support multiple types of "queue" like (bee-queue, cron, etc) in the same way as a task monitor, so far it supports only "bull"
