Execute SQL Server queries against Google Contacts data from Node.js.
You can use CData Connect Cloud to query Google Contacts data through a SQL Server interface. Follow the procedure below to create a virtual database for Google Contacts in Connect Cloud and start querying using Node.js.
CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Google Contacts, allowing you to easily query live Google Contacts 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 Google Contacts, leveraging server-side processing to quickly return Google Contacts data.
Configure Google Contacts Connectivity for NodeJS
Connectivity to Google Contacts from NodeJS is made possible through CData Connect Cloud. To work with Google Contacts data from NodeJS, we start by creating and configuring a Google Contacts connection.
- Log into Connect Cloud, click Sources, and then click Add Connection
- Select "Google Contacts" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Google Contacts.
You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.
- Click Create & Test
-
Navigate to the Permissions tab in the Add Google Contacts Connection page and update the User-based permissions.


Add a Personal Access Token
When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Google Contacts data from Node.js.
Query Google Contacts from Node.js
The following example shows how to define a connection and execute queries to Google Contacts with the SQL Server module. You will need the following information:
- server: tds.cdata.com
- port: 14333
- user: a Connect Cloud user (e.g. [email protected])
- password: the PAT for the above user
- database: The connection you configured for Google Contacts (GoogleContacts1)
Connect to Google Contacts data and start executing queries with the code below:
var sql = require('mssql') var config = { server: 'tds.cdata.com', port: 14333, user: '[email protected]', //update me password: 'CONNECT_USER_PAT', //update me options: { encrypt: true, database: 'GoogleContacts1' } } sql.connect(config, err => { if(err){ throw err ; } new sql.Request().query('SELECT * FROM Friends', (err, result) => { console.dir(result) }) }); sql.on('error', err => { console.log("SQL Error: " ,err); })
