Query Hugging Face Data as a MySQL Database in Node.js

You can use the SQL Gateway from the ODBC Driver for Hugging Face to query Hugging Face data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and start querying using Node.js.

Connect to Hugging Face 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.

HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

Using API Key Authentication

To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

1. Log in to your HuggingFace account at https://huggingface.co
2. Navigate to Settings > Access Tokens
3. Click "New token" to create a new access token
4. Select the appropriate permissions (read or write)
5. Copy the token value

After obtaining your access token, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your HuggingFace access token.

Example connection string

Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Hugging Face data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Hugging Face from Node.js

The following example shows how to define a connection and execute queries to Hugging Face with the mysql module. You will need the following information:

• Host name or address, and port: The machine and port where the MySQL remoting service is listening for MySQL connections.
• Username and password: The username and password of a user you authorized on the Users tab of the SQL Gateway.
• Database name: The DSN you configured for the MySQL remoting service.

Connect to Hugging Face data and start executing queries with the code below:

var mysql = require('mysql');
var connection = mysql.createConnection({
 host : 'localhost',
 database : 'CData API Sys',
 port	 : '3306',
 user : 'mysql_user',
 password : 'test'
});
connection.connect();
connection.query('SELECT * FROM Collections', function(err, rows, fields) {
 if (err) throw err;
 console.log(rows);
});

connection.end();
