使用Webpack与Mongoose - mongoose.model不是一个功能 [英] Using Webpack with Mongoose - mongoose.model is not a function

问题描述

我正在使用Webpack在浏览器中使用require模块;但是，我收到以下错误：

 未捕获TypeError：mongoose.model不是一个函数
在对象<匿名> （bundle.js：44338）
在__webpack_require__（bundle.js：20）
在Object。< anonymous> （bundle.js：48）
在Object。< anonymous> （bundle.js：68）
在__webpack_require__（bundle.js：20）
在bundle.js：40 
在bundle.js：43 
  

我知道mongoose根据 http://mongoosejs.com/docs/browser.html 和我甚至包括建议的脚本标记，仍然收到错误。

我还使用mongoose正确导出了我的模块：

  var mongoose = require（'mongoose ）; 
 var Schema = mongoose.Schema; 
 
 var ProductSchema = new Schema（{
 imageURL：String，
 productName：String，
 productType：String，
 price：String 
 }，{collection：'products'}）; 
 
 module.exports = mongoose.model（'products'，ProductSchema）; 
  

我的webpack.config.js也配置正确

  var webpack = require（'webpack'）; 
 var path = require（'path'）; 
 var fs = require（'fs'）; 
 var request = require（'request'）; 
 var CaseSensitivePathsPlugin = require（'case-sensitive-paths-webpack-plugin'）; 
 
 module.exports = {
条目：./main.js，
输出：{
路径：__dirname，
 filename：bundle .js
}，
模块：{
装载机：[
 {test：/\ json$/，loader：'json-loader'} 
 ] 
}，
 resolve：{
 extensions：[''，'.webpack.js'，'.web.js'，'.js'，'.json'] 
 $，
 node：{
控制台：'空'，
 fs：'空'，
 net：'空' 
} 
} 
  

为什么会发生这种情况？如何解决？

解决方案

mongoose.model只是服务器端。在客户端/浏览器上没有模型，因为客户端/浏览器没有数据库连接。您可以使用mongoose.Document，为了保持模式DRY / isomorph。

I'm using Webpack to use require modules in the browser; however, I'm getting the following error:

Uncaught TypeError: mongoose.model is not a function
    at Object.<anonymous> (bundle.js:44338)
    at __webpack_require__ (bundle.js:20)
    at Object.<anonymous> (bundle.js:48)
    at Object.<anonymous> (bundle.js:68)
    at __webpack_require__ (bundle.js:20)
    at bundle.js:40
    at bundle.js:43

I know mongoose has some limitations in the browser according to http://mongoosejs.com/docs/browser.html and I even included the script tag suggested and still receiving the error.

I have also exported my module using mongoose correctly:

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

var ProductSchema = new Schema({
    imageURL: String,
    productName: String,
    productType: String,
    price: String
}, {collection: 'products'});

module.exports = mongoose.model('products', ProductSchema);

My webpack.config.js is configured correctly as well

var webpack = require('webpack');
var path = require('path');
var fs = require('fs');
var request = require('request');
var CaseSensitivePathsPlugin = require('case-sensitive-paths-webpack-plugin');

module.exports = {
    entry: "./main.js",
    output: {
        path: __dirname,
        filename: "bundle.js"
    },
    module: {
    loaders: [
      { test: /\.json$/, loader: 'json-loader' }
        ]
    },
    resolve: {
        extensions: ['', '.webpack.js', '.web.js', '.js', '.json']
    },
    node: {
        console: 'empty',
        fs: 'empty',
        net: 'empty',
        tls: 'empty'
    }
}

Why is this occurring? And how can this be resolved?

解决方案

mongoose.model is server side only. On the client/browser there is no model, because the client/browswer has no database connection. You can use mongoose.Document though, in order to keep schemas DRY/isomorph.
