node js 读取mysql

1、新版node自带npm 2、下载npm不需要node命令 3、懒得配环境变量、直接把生成的npm复制到报错目录，再把mysql模块复制回来

 

var mysql = require('mysql');
var conn = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'root',
    database:'nodejs',
    port: 3306
});
conn.connect();
conn.query('SELECT * from fleam', function(err, re) {
    if (err) {throw err;}
else{
console.log(re);
}
    
});
conn.end();
