Use node-odbc to execute SQL queries against Trello data from 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 Trello, you can access live Trello 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 Trello data.
With built-in optimized data processing, the CData ODBC Driver offers unmatched performance for interacting with live Trello data in Node.js. When you issue complex SQL queries from Node.js to Trello, the driver pushes supported SQL operations, like filters and aggregations, directly to Trello and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Trello 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.
Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.
Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.
- Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
- OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.
Building node-odbc
In order to connect to Trello 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 Trello from Node.js
With the ODBC Driver installed, a DSN Configured, and node-odbc built, we are ready to query live Trello data from a Node.js app. The sample code below connects to a specific DSN and queries the Boards table.
myscript.js
const odbc = require('odbc'); async function queryTrello() { const connection = await odbc.connect(`DSN=CData Trello Source`); const data = await connection.query('SELECT BoardId, Name FROM Boards'); console.log(data); } queryTrello();
Once you write the app, use node to execute the script:
node myscript.js
