Query Microsoft Exchange Data as a SQL Server Database in Node.js

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

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

Configure Microsoft Exchange Connectivity for NodeJS

Connectivity to Microsoft Exchange from NodeJS is made possible through CData Connect Cloud. To work with Microsoft Exchange data from NodeJS, we start by creating and configuring a Microsoft Exchange connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Microsoft Exchange" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Microsoft Exchange.

   Specify the User and Password to connect to Exchange. Additionally, specify the address of the Exchange server you are connecting to and the Platform associated with the server.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Microsoft Exchange Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. 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, you are ready to connect to Microsoft Exchange data from Node.js.

Query Microsoft Exchange from Node.js

The following example shows how to define a connection and execute queries to Microsoft Exchange with the SQL Server module. You will need the following information:

• server: tds.cdata.com
• port: 14333
• user: a Connect Cloud user (e.g. user@mydomain.com)
• password: the PAT for the above user
• database: The connection you configured for Microsoft Exchange (Exchange1)

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

var sql = require('mssql')
var config = {
	server: 'tds.cdata.com',
	port: 14333, 
	user: 'user@mydomain.com', //update me
	password: 'CONNECT_USER_PAT', //update me	
	options: {
		encrypt: true,
		database: 'Exchange1'
	}
}

sql.connect(config, err => { 
    if(err){
        throw err ;
    }
    new sql.Request().query('SELECT * FROM Contacts', (err, result) => {
        console.dir(result)
    })
        
});

sql.on('error', err => {
    console.log("SQL Error: " ,err);
})
