CData Connect



Execute MySQL queries against Plaid data from Node.js.

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

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

Create a Virtual MySQL Database for Plaid 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 "Plaid" from Available Data Sources.
  3. Plaid uses OAuth to authenticate. Click Test Database to authenticate with Plaid.
  4. 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 Plaid data from any MySQL client.

Query Plaid from Node.js

The following example shows how to define a connection and execute queries to Plaid 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 Plaid (plaiddb)

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

connection.end();
