Connect to Notion Data in JRuby

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

Configure a JDBC Connection to Notion 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 Notion\lib).

JRuby natively supports JDBC, so you can easily connect to Notion 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 Notion Profile on disk (e.g. C:\profiles\Notion.apip). Next, set the ProfileSettings connection property to the connection string for Notion (see below).

Notion API Profile Settings

Go to https://www.notion.so/my-integrations, create an internal integration, configure the name and workspace, then copy the Internal Integration Token from the Secrets section.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Notion 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 Notion:

jdbc:api:Profile=C:\profiles\Notion.apip;ProfileSettings='APIKey=your_integration_token';

Create a JRuby App with Connectivity to Notion 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 Notion 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Notion.apip;ProfileSettings='APIKey=your_integration_token';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Object FROM BlockChildren")
while (rs.next) do
 puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
