Creating a subscription with initial position as "earliest"

My use case: I have a shared subscription with a bunch of consumers. Suppose, all the consumers die and there are messages still being published to the topic. When a new consumer comes in, I want it to read from the last unacknowledged message so that no messages are lost or unprocessed.

So, I want to create a subscription with initial subscription position as `earliest` but I don't see any option to set the initial position. Also, What is default behavior? `earliest` or `latest` ?

首先定位 NodeJS 客户端中的订阅创建 API，并跟踪其初始位置的选择方式。检查现有行为以及关于默认值的文档，然后定义该选项，并验证新的消费者可以从请求的位置开始，而不会丢失未确认的消息。
