Isn't it an overkill to create both followers and followings schema?.

[aseerkt]

Can't we just keep track of followers and followings from a single schema?.

For example, combining both of them into Follow.js like shown below.

// Follow.js
const FollowSchema = new Schema({
  follower: {
    type: Schema.ObjectId,
    ref: 'User'
  },
  following: {
    user: {
      type: Schema.ObjectId,
      ref: 'User'
    }
 },
});

I am noob btw when it comes to DB design, especially with NoSQL.
