Connect to Discord Data in JRuby

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Discord makes it easy to integrate connectivity to live Discord data in JRuby. This article shows how to create a simple JRuby app that connects to Discord data, executes a query, and displays the results.

Configure a JDBC Connection to Discord Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Discord\lib).

JRuby natively supports JDBC, so you can easily connect to Discord and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

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

Discord API Profile Settings

Visit the Discord Developer Portal, create or select an application, and navigate to the OAuth2 section to obtain your Client ID and Client Secret.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Discord JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.api.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for Discord:

jdbc:api:Profile=C:\profiles\Discord.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

Create a JRuby App with Connectivity to Discord Data

Create a new Ruby file (for example: APISelect.rb) and open it in a text editor. Copy the following code into your file:

require 'java'
require 'rubygems'
require 'C:/Program Files/CData/CData JDBC Driver for Discord 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Discord.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Name FROM Application")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

With the file completed, you are ready to display your Discord data with JRuby. To do so, simply run your file from the command line:

jruby -S APISelect.rb
