});

var commentSchema = new Schema({

  PeopleID:{type:ObjectId,ref:'User'},
});
//Message ToID 欄位 與 User _id 關聯

Async

(1)Promise

var result = [];
Project.find({}).exec().then(function(projects){
	result.push(projects)
	return User.find({}).exec()
}).then(function(users){
	result.push(users)
	return Message.find({}).exec()
}).then(function(msgs){
	result.push(msgs)
	res.send(result)
})

(2)Async / Await

需要nodejs v7.6或 babel

app.router("/",async function(req,res){
  var users = await User.find({}).exec();
  var projects = await Project.find({}).exec();
  res.send({
    users:users,
    projects:projects
  })
});
