Query Email Data as a MySQL Database in Node.js

Execute MySQL queries against Email data from Node.js.

You can use the CData Cloud Hub to query Email data through a MySQL interface. Follow the procedure below to create a virtual database for Email in the Cloud Hub and start querying using Node.js.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Email, allowing you to easily query live Email data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Email, leveraging server-side processing to quickly return Email data.

Create a Virtual MySQL Database for Email Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "Email" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Email.

    The User and Password properties, under the Authentication section, must be set to valid credentials. The Server must be specified to retrieve emails and the SMTPServer must be specified to send emails.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Email data from any MySQL client.

Query Email from Node.js

The following example shows how to define a connection and execute queries to Email with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for Email (emaildb)

Connect to Email data and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'emaildb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Mailboxes', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
