mongoose - 将 bluebird 与 mongoose 一起使用的正确方法是什么？

Question

来自 Bluebird 文档:

// Mongoose
var Promise = require("bluebird");
Promise.promisifyAll(require("mongoose"));

来自 Mongoose 文档:

var mongoose = require("mongoose");
// Use bluebird
mongoose.Promise = require('bluebird');

我应该使用哪一个？

Answer 1

这里有两个讨论

• Ability to specify which ES6 promises library mongoose uses
• use Q.js

People asked for promises support and Mongoose is quite a mature library now over 4 years old- mpromise was chosen because it looked like a good way to add promise support at a time.

所以我们可以从bluebird中找到这个用法，

Promise.promisifyAll(require("mongoose"));

mongoose.Promise = require('bluebird'); will make mongoose use native promises. You should be able to use any ES6 promise constructor though, but right now we only test with native, bluebird, and Q

所以他们俩都OK。
