如何在 CoffeeScript 中连接 MySQL 数据库。如何运行它。我使用 node.js 创建了 MySQL 连接并在终端中显示记录,但如何在浏览器上显示它。我正在使用 ECO 模板在浏览器上显示。我需要使用咖啡脚本进行数据库连接

文件 - db_test.js

  var mysql = require("mysql");
  var con = mysql.createConnection({
    host: "localhost",
    user: "root",
    password: "",
    database: "test"
});

  con.connect(function(err){
    if(err){
       console.log('Error connecting to Db');
       return;
    }
    console.log('Connection established');
});

 con.query('SELECT * FROM users',function(err,rows){
      if(err) throw err;
      for (var i = 0; i < rows.length; i++) {
       console.log(rows[i].username);
    };
});

con.end(function(err) {
  // The connection is terminated gracefully
  // Ensures all previously enqueued queries are still
  // before sending a COM_QUIT packet to the MySQL server.
});
