CData Connect



Execute MySQL queries against LinkedIn data from Node.js.

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

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

Create a Virtual MySQL Database for LinkedIn 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 "LinkedIn" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to LinkedIn. LinkedIn uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with LinkedIn. For more information refer to our authentication guide.
  4. Click Test Database.
  5. 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 LinkedIn data from any MySQL client.

Query LinkedIn from Node.js

The following example shows how to define a connection and execute queries to LinkedIn 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 LinkedIn (linkedindb)

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

connection.end();
