介绍

Bull 是 BullMQ 的遗留版本。由于它在今天仍然被大量使用，所以它也被用于 bug 的维护，而不是用于新的主要功能。 如果你想使用一个经过战斗测试的队列库，你不需要更好的 typescript 集成，也不需要最新的特性，你可以在未来几年使用这个库。

所使用的

长期以来，Bull 一直是 NodeJS 生态系统的一部分，许多组织在商业和开源项目中都使用了 Bull。 特别提到几点:




The fastest, most reliable, Redis-based queue for Node.
Carefully written for rock solid stability and atomicity.
