我正在尝试使用browserify将我的mongoose模式导入到一个js文件中，我计划在客户端使用它。这里有两个模式：answer.js

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const answerSchema = new Schema({
    body : String,
    likes : Number,
    author : {
        type : Schema.Types.ObjectId,
        ref : 'User'
    },
    likedBy : [
        {
            type : Schema.Types.ObjectId,
            ref : 'User'
        }
    ]
});

module.exports = mongoose.model("Answer",answerSchema);

问题.js

const mongoose = require('mongoose');
const Answer = require('./answer');
const Schema = mongoose.Schema;

const QuestionSchema = new Schema({
    title : String,
    description : String,
    likes : Number,
    author : {
        type : Schema.Types.ObjectId,
        ref : 'User'
    },
    answers : [
        {
            type : Schema.Types.ObjectId,
            ref : 'Answer'
        }
    ],
    likedBy : [
        {
            type : Schema.Types.ObjectId,
            ref : 'User'
        }
    ]
});

QuestionSchema.post('findOneAndDelete', async function(doc) {
    if(doc) {
        await Answer.deleteMany({
            _id : {
                $in : doc.answers
            }
        });
    }
});

module.exports = mongoose.model('Question',QuestionSchema);

我使用browserify在一个名为islike.js的文件中使用它们。我在linux终端上写了以下内容

browserify -r ./question.js:questionModel -r ./answer.js:answerModel > ../public/js/isLikedBundle.js

在show.ejs文件中，我执行了以下操作：

<script src="/js/isLikedBundle.js"></script>
<script src="/js/isLiked.js"></script>

为了测试是否一切正常，我在isliked.js中执行了以下操作：

const Question = require('questionModel');
const Answer = require('answerModel');
console.log(Question);
console.log(Answer);

我在控制台上得到了以下输出：

ƒ n(t,o){return function(t,e){if(!(t instanceof e))throw new TypeError("Cannot call a class as a function")}(this,n),e.call(this,t,r,o)}
ƒ n(t,o){return function(t,e){if(!(t instanceof e))throw new TypeError("Cannot call a class as a function")}(this,n),e.call(this,t,r,o)}

我不能使用任何 Mongoose 函数。请帮忙！！！
