For schema, you probably want something like this:
const messageSchema = new mongoose.Schema({ subject: String, body: String, seen: Boolean, sender: { type: mongoose.Schema.Types.ObjectId, ref: "User" } recipient: { type: mongoose.Schema.Types.ObjectId, ref: "User" }})const userSchema = new mongoose.Schema({ username: String, email: Boolean, type: String})var Message = mongoose.model('Message', messageSchema);var User = mongoose.model('User', userSchema);For querying, you can find everything you need here
