先npm install mysql

然后代碼中就可以require('mysql');

就可以使用了

var mysql = require('mysql');var pool = mysql.createPool(config);pool.getConnection(function(err, connection) {// Use the connectionconnection.query( 'SELECT something FROM sometable', function(err, rows) {// And done with the connection.connection.end();// Don't use the connection here, it has been returned to the pool.});});

js代碼透明，你在寫好代碼提交給別人的時候，或是部署的時候，用

Jshaman
