Query EDGAR Online Data as a MySQL Database in Node.js

Execute MySQL queries against EDGAR Online data from Node.js.

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

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

Create a Virtual MySQL Database for EDGAR Online Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "EDGAR Online" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to EDGAR Online.
    1. Navigate to https://developer.edgar-online.com/ and create an account.
    2. Register a new application and retrieve the AppKey. You should select one of the available Web APIs this application will use like HackPack, Insider Trades or Institutional Ownership.
      Note: HackPack is the most important Web API that an application can use since it supports a large number of endpoints. If you are getting the "Access Denied" error you must create a new app and select the correct Web API which supports the resource you are querying.
    3. After successfully creating a new app, you can access your keys through your "my account" area. Set the AppKey connection property value equal to the Key of your application.
  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 EDGAR Online data from any MySQL client.

Query EDGAR Online from Node.js

The following example shows how to define a connection and execute queries to EDGAR Online with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for EDGAR Online (edgaronlinedb)

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

connection.end();
