javascript - React JS MSSQL 拒绝导入 mssql

Question

我正在尝试导入 mssql 我有一个 js 文件，它自己可以正常工作，但我需要这样做，以便我可以从 react js 环境中调用该函数，而不仅仅是节点

import React, { Component } from 'react';

import TextInput from '../SmallBits/FormItems/TextInput';

import sql from 'mssql';
//or
var sql = require('mssql');

var dbConfig = {
    server: 'localhost',
    database: 'TestDB',
    user: 'andy',
    password: 'andy',
    port: 1433
};

export default class LeftBox extends Component {
    constructor(props){
        super(props);
        this.state = {
        name: '',
        forename: '',
        surname: '',
        caseID: '',
        address: ''
    }
    this.handleSurnameChange = this.handleSurnameChange.bind(this);
    this.handleForenameChange = this.handleForenameChange.bind(this);
    this.handleCaseIDChange = this.handleCaseIDChange.bind(this);
    this.handleAddressChange = this.handleAddressChange.bind(this);
}

loadEmployees() {
    var dbConn = new sql.ConnectionPool(dbConfig);
    dbConn.connect().then(function () {
        var request = new sql.Request(dbConn);
        request.query("select * from EmployeeTable").then(function (recordSet) {
            console.log(recordSet);
            return recordSet;
            dbConn.close();
        }).catch(function (err) {
            console.log(err);
            dbConn.close();
        });
    }).catch(function (err) {
        console.log(err);
    });
}

这就是顶部机器人中被调用的导入和 require 语句的所有代码给我同样的错误，模块未找到:无法解析 'C:\Users\wilsona.CHECKMATE\Desktop 中的 'mssql'\reactapp\Workspace\savvy-crm-test\src\components\Parts\Boxes' 即使 mssql 是全局安装的，我也应该在本地安装吗

这似乎类似于 Errors with node-mssql in a webpack-bundled React app

MSSQL server connection libraries are not client-side javascript libraries. There is absolutely no way you can make TCP SQL connections from a web browser, even if you wrote your own library.

For security reasons, you would never want to allow client-side access to the SQL Server. You need to spin up server-side environment (e.g. Node/Express) to expose an API to the client applications.
