與Mongoose一起使用Webpack - mongoose.model不是函數

Question

我正在使用Webpack在瀏覽器中使用require模塊;然而，我發現了以下錯誤：

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 

我知道貓鼬根據http://mongoosejs.com/docs/browser.html和我甚至包括腳本標籤建議，仍然收到錯誤在瀏覽器中的一些限制。

我還遠銷我用貓鼬模塊正確：

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webpack.config.js被正確的配置以及

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' 
    } 
} 

爲什麼會發生這種情況？如何解決這個問題？

Answer 1

mongoose.model只是服務器端。在客戶端/瀏覽器中沒有模型，因爲客戶端/瀏覽器沒有數據庫連接。儘管如此，您仍然可以使用mongoose.Document，以保持模式DRY/isomorph。
