要求或不要求猫鼬{模型，架构}？

Question

Is there any difference between requiring twice as opposed to just destructuring model and Schema from the existing variable mongoose already created?

Here are the two different examples. In a Node app is there a difference between the two following code examples outside of basic syntax and readability.

const mongoose = require('mongoose');
const { model, Schema } = mongoose;

const mongoose = require('mongoose')
const { model, Schema } = require('mongoose')

It seems they both work fine. I assume it's a very simple question to answer.

Answer 1

If you need the mongoose object later, then go with the first one. If you want to use only model and Schema then go simply with:

const { model, Schema } = require('mongoose')

You don't want to load the module twice, there is a performance difference.
