Query Drift 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 API Driver for ODBC, you can access live Drift 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 Drift data.

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

Connecting to Drift 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 Drift Profile on disk (e.g. C:\profiles\Drift.apip). Next, set the ProfileSettings connection property to the connection string for Drift (see below).

Drift API Profile Settings

Drift uses OAuth-based authentication.

You must first register an application here: https://dev.drift.com. Your app will be assigned a client ID and a client secret. Set these in your connection string via the OAuthClientId and OAuthClientSecret properties. More information on setting up an OAuth application can be found at https://devdocs.drift.com/docs/.

After setting the following options in the ProfileSettings connection property, you are ready to connect:

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

Building node-odbc

In order to connect to Drift 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 Drift from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryAPI() {
    const connection = await odbc.connect(`DSN=CData API Source`);
    const data = await connection.query('SELECT Id, DisplayName FROM Contacts');
    console.log(data);
}

queryAPI();

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

node myscript.js
