Query Gmail Data as a MySQL Database in Node.js

Execute MySQL queries against Gmail data from Node.js.

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Gmail, allowing you to easily query live Gmail 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 Gmail, leveraging server-side processing to quickly return Gmail data.

Create a Virtual MySQL Database for Gmail 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 "Gmail" from Available Data Sources.
  3. 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 Gmail data from any MySQL client.

Query Gmail from Node.js

The following example shows how to define a connection and execute queries to Gmail 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 Gmail (gmaildb)

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

connection.end();
