将create-react-app reactJs与mysql连接

Question

I have problem in connecting my create-react-app with mysql using npm.

Its working in nodejs when i tried seperately without npm. But, When i trying to connect using npm install mysql, It throws me an error...

TypeError: http.IncomingMessage is undefined ./node_modules/express/lib/request.js

Here is my code:

var express = require('express');
var mysql = require('mysql');

var connection =mysql.createConnection({
    host: 'localhost',
    user: 'user',
    password: '',
    database: 'reactproject'
});

connection.connect(function(err){
    if(!err) {
        console.log("Database is connected ... nn");
    } else {
        console.log("Error connecting database ... nn");
    }
});

Answer 1

This will not work from react-app, since react code will run from client side. You should use my-sql connection in different app and run in different port and call as api connection.

Thanks.

从@ashik答案添加是正确的，但是如果您仍然想同​​时使用MySQL和reactjs，则可以从创建自己的样板开始，在那里您可以在服务器端使用MySQL并创建APi / web服务，而不必分开APi服务器和客户端项目reactjs。
