Query MailerLite Data as a SQL Server Database in Node.js

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

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

Configure MailerLite Connectivity for NodeJS

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

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "MailerLite" from the Add Connection panel

3. Enter the necessary authentication properties to connect to MailerLite.

   Start by setting the Profile connection property to the location of the MailerLite Profile on disk (e.g. C:\profiles\MailerLite.apip). Next, set the ProfileSettings connection property to the connection string for MailerLite (see below).

   MailerLite API Profile Settings

   Obtain your API Key from the Integrations page in your MailerLite account dashboard.

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

Add a Personal Access Token

When connecting to Connect AI 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 AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the 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 and a PAT generated, you are ready to connect to MailerLite data from Node.js.

Query MailerLite from Node.js

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

• server: tds.cdata.com
• port: 14333
• user: a Connect AI user (e.g. [email protected])
• password: the PAT for the above user
• database: The connection you configured for MailerLite (API1)

Connect to MailerLite 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: 'API1'
	}
}

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

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