Query Wave Financial 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 Wave Financial, you can access live Wave Financial 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 Wave Financial data.

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

Connecting to Wave Financial 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.

Connect using the API Token

You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:

1. Log in to your Wave account and navigate to "Manage Applications" in the left pane.
2. Select the application that you would like to create a token for. You may need to create an application first.
3. Click the "Create token" button to generate an APIToken.

Connect using OAuth

If you wish, you can connect using the embedded OAuth credentials. See the Help documentation for more information.

Building node-odbc

In order to connect to Wave Financial 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 Wave Financial from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryWaveFinancial() {
    const connection = await odbc.connect(`DSN=CData WaveFinancial Source`);
    const data = await connection.query('SELECT Id, DueDate FROM Invoices');
    console.log(data);
}

queryWaveFinancial();

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

node myscript.js
