第一步

在 中搜索 mysql,因为这里搜到的都是 node 的包,搜到的以第一个就是啦。

第二步

安装:

npm install mysql
使用:

var mysql = require('mysql');// 1. 创建连接var connection = mysql.createConnection({     host: 'localhost',  user: 'root',  password: 'root',  database: 'users' // 对不起,我一不小心把数据库名字和表名起成一样的,你知道就行});// 2. 连接数据库 打开冰箱门connection.connect();// 3. 执行数据操作 把大象放到冰箱 所有的sql语句都往这写connection.query('SELECT * FROM `users`', function (error, results, fields) {     if (error) throw error;  console.log('The solution is: ', results);});// connection.query('INSERT INTO users VALUES(NULL, "admin", "123456")', function (error, results, fields) {   //   if (error) throw error;//   console.log('The solution is: ', results);// });// 4. 关闭连接 关闭冰箱门connection.end();
