How do I paginate with populate in Mongoose?
populate works with skip and limit. Post.find().sort({ createdAt: -1 }).skip(20).limit(20).populate('authorId', 'firstName'). Just be careful with large limits; populate does an extra query for all referenced docs.

Use populate on read: Post.findById(id).populate('authorId', 'firstName lastName'). Returns the post with the author object embedded. The client gets everything in one response. Always select specific fields.
For lists with many relationships, fetch parents and referenced docs in parallel, return both, let the client connect them. Avoids N+1 and avoids large nested payloads. Example: { posts: [...], authors: [...] }.
When deleting a user, delete their posts and messages too. Use deleteMany for each related collection, then delete the user. Do it in a transaction if your MongoDB supports it, so a failure rolls back.
