Query Google Analytics Data through ODBC in Node.js

Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser. With the CData ODBC Driver for Google Analytics, you can access live Google Analytics data from Node.js apps and scripts. In this article, we walk through installing node-odbc and the required tools to create a simple Node.js app with access to live Google Analytics data.

With built-in optimized data processing, the CData ODBC Driver offers unmatched performance for interacting with live Google Analytics data in Node.js. When you issue complex SQL queries from Node.js to Google Analytics, the driver pushes supported SQL operations, like filters and aggregations, directly to Google Analytics and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Google Analytics 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.

Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

In addition to the OAuth values, set Profile to the profile you want to connect to. This can be set to either the Id or website URL for the Profile. If not specified, the first Profile returned will be used.

Building node-odbc

In order to connect to Google Analytics through the CData ODBC Driver, you need to build node-odbc manually (after installing the required tools).

Installing the Required Tools

The following commands install the tools required to build node-odbc (note the -g parameter, which installs the tools globally).

npm i -g windows-build-tools
npm i -g node-gyp

Building node-odbc

After installing the required tools, create a directory for the Node.js app and install odbc (which builds the binary for us to use in our Node.js script).

mkdir nodeodbc
cd nodeodbc
npm i -g node

Querying Google Analytics from Node.js

With the ODBC Driver installed, a DSN Configured, and node-odbc built, we are ready to query live Google Analytics data from a Node.js app. The sample code below connects to a specific DSN and queries the Traffic table.

myscript.js

const odbc = require('odbc');

async function queryGoogleAnalytics() {
    const connection = await odbc.connect(`DSN=CData GoogleAnalytics Source`);
    const data = await connection.query('SELECT Browser, Sessions FROM Traffic');
    console.log(data);
}

queryGoogleAnalytics();

Once you write the app, use node to execute the script:

node myscript.js
