CData Connect



Execute MySQL queries against WordPress data from Node.js.

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

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

Create a Virtual MySQL Database for WordPress Data

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

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

    To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

    See the Getting Started guide in the CData driver documentation for more information.

  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 WordPress data from any MySQL client.

Query WordPress from Node.js

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

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

Connect to WordPress 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 : 'wordpressdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Categories', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
