使用Sequelize和Webpack - 依赖和加载器错误

Question

尝试使用Postgres数据库配置Sequelize。我正在使用Webpack捆绑我的应用程序。当我刚刚整合Sequelize：

var Sequelize = require('sequelize'); 

我得到我的终端以下错误：

我认为这是一个的WebPack相关的问题，因为我可以得到Sequelize在项目没有按”运行不要使用webpack。我只是不确定它是什么。它看起来最后两个可能与需要装载器的webpack（不知道哪些）和其他警告是依赖关系相关或依赖是一个表达式（不知道这意味着什么）。

任何和所有的帮助，非常感谢。谢谢。

更新：有人指出，这是在客户端进行的，这是错误的方式去做这件事。我搬到这个Sequelize数据库配置到我server.js文件（持有我的快速配置）和它的作品以及的WebPack不再界面与它：

const express = require('express'); 
const app = express(); 
var Sequelize = require('sequelize'); 

var connection = new Sequelize('dev', 'dace', 'root', { 
    dialect: 'postgres', 
}); 


const PORT = (process.env.PORT || 3000); 

app.get('/', function(req, res) { 
    var Article = connection.define('article', { 
    name: Sequelize.STRING, 
    }) 

    connection.sync().then(function() { 
    Article.create({ 
     name: 'Dace' 
    }); 
    }); 
}) 

app.listen(PORT, function() { 
    console.log(`Listening on port ${PORT}...`); 
}); 

不是如何最终应配置，但刚够得到我想要做的一个工作示例。
