Query Coinbase Data as a MySQL Database in Node.js

You can use the SQL Gateway from the ODBC Driver for Coinbase to query Coinbase data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and start querying using Node.js.

Connect to Coinbase Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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

Coinbase API Profile Settings

Coinbase uses OAuth-based authentication.

First you need to register an OAuth app with Coinbase. This is done from your account under 'Settings' > 'API Access' > 'New OAuth2 Application'.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to OAuth.
• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
• OAuthClientId: Set this to the ClientID that is specified in you app settings.
• OAuthClientSecret: Set this to the ClientSecret that is specified in you app settings.
• CallbackURL: Set this to the Redirect URI you specified in your app settings.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Coinbase data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Coinbase from Node.js

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

• Host name or address, and port: The machine and port where the MySQL remoting service is listening for MySQL connections.
• Username and password: The username and password of a user you authorized on the Users tab of the SQL Gateway.
• Database name: The DSN you configured for the MySQL remoting service.

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

var mysql = require('mysql');
var connection = mysql.createConnection({
 host : 'localhost',
 database : 'CData API Sys',
 port	 : '3306',
 user : 'mysql_user',
 password : 'test'
});
connection.connect();
connection.query('SELECT * FROM Deposits', function(err, rows, fields) {
 if (err) throw err;
 console.log(rows);
});

connection.end();
