使用 Sequelize 和 Webpack - 依赖和加载器错误

Question

正在尝试使用 Postgres 数据库配置 Sequelize。我正在使用 Webpack 来捆绑我的应用程序。当我将 Sequelize 与 just:

集成时

var Sequelize = require('sequelize');

我的终端出现以下错误：

我认为这是一个与 webpack 相关的问题，因为我可以在不使用 webpack 的项目中获得 Sequelize 运行。我只是不确定它是什么。看起来最后两个可能与 webpack 需要加载器有关（不确定哪些），其他警告与依赖相关或依赖是一个表达式（不确定那是什么意思）。

非常感谢任何帮助。谢谢

更新：有人向我指出这是在客户端完成的，这是错误的处理方式。我将这个 Sequelize 数据库配置移动到我的 server.js 文件（包含我的快速配置）并且它运行良好，因为 webpack 不再与它交互：

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}...`);
});

不是它最终应该如何配置，而是足以获得我正在尝试做的工作的示例。
