How to create Post Schema in mongoose?

Question

MongoDB

Hello, I want to create a document model for a post in which there should be a rating, for example, likes and reposts, and which should store an array of c id users and a counter for the length of these arrays to display numbers on the front, how to implement this correctly, was it worth creating a separate type of model for the rating of a post and how to link it together with the model of the post itself? I will be grateful for help
