How to query several MongoDB collections at once?

Question

For example, I have two collections A and B and I have a find() query per each collection with unrelated data to return. What I need is to combine these two query results and execute limit() and skip() operations. Executing these two queries sequentially is a pretty complex task.

Answer 1

I believe you can do something like that:

const [docs1, docs2] = await Promise.all([
      Model1.find().skip().limit().exec(),
      Model2.find().skip().limit().exec()
])
