node-jdbc-driver is a JDBC API wrapper for Node.js, providing methods to manage database connections, execute queries and update statements, and retrieve database information such as table and column structures in a database-independent manner.

Dependencies upto date Status Downloads Npm version


  • Simplified JDBC Usage: Provides an intuitive API to manage JDBC database connections, execute queries, and handle update statements, abstracting away low-level complexities.

  • Multiple Database Support: Seamlessly connect to different types of databases, including Hive, PostgreSQL, Tibero, and SQLite, with a unified interface.

  • Flexible Configuration: Easily configure database connections using either host, port, database name, username, and password or via custom JDBC connection with driver jars and connection URLs.

  • Connection Pooling: Benefit from built-in connection pooling support to efficiently manage and reuse database connections, enhancing application performance.

  • Query Execution: Execute custom SQL queries and retrieve results in a straightforward manner, enabling you to interact with your database effortlessly.

  • Database Structure Information: Retrieve comprehensive information about table and column structures using simple methods, enabling you to work with your database schema efficiently.

  • Data Manipulation: Perform essential data manipulation tasks such as counting rows, finding rows based on criteria, retrieving all rows from a table, and more.

  • Data Definition Language (DDL) Support: Execute DDL queries to manage the structure of your database, including creating and altering tables, views, and indexes.


To install the package, use the following command:

npm install --save node-jdbc-driver

Loading and configuring the module

You can initialize the JDBC driver using either CommonJS or ES6 syntax:

// CommonJS
const { default: JdbcDriver, ConnectionType } = require("node-jdbc-driver");

// ES6
import JdbcDriver, { ConnectionType } from 'node-jdbc-driver';

Common Usage

Below are some minimal usage examples demonstrating how to use the node-jdbc-driver package.

Connection Setup

For different types of databases, you need to provide specific connection details.

Available Connection types

ConnectionType.hive // for hive connection
ConnectionType.postgreSql // for postgreSql connection
ConnectionType.sqlite // for sqlite connection
ConnectionType.tibero // for tibero connection
ConnectionType.custom // Establish a JDBC connection using a custom driver

Hive and PostgreSQL Connection

For Hive and PostgreSQL connections, provide the host, port, database name, username, and password:

const host = '<host>';
const port = '<port>';
const database = '<database_name>';
const username = '<username>';
const password = '<password>';

// Set optional parameters
const minpoolsize = '<min_pool_size>'
const maxpoolsize = '<max_pool_size>'

// For Hive
const jdbc = new JdbcDriver(ConnectionType.hive, { host, port, database, username, password });

// For Hive with connection url
const jdbcUrl = 'jdbc:hive2://<host>:<port>/<database>'
const jdbc = new JdbcDriver(ConnectionType.hive, { jdbcUrl, username, password });

// For PostgreSql
const jdbc = new JdbcDriver(ConnectionType.postgreSql, { host, port, database, username, password });

// For PostgreSql with connection url
const jdbcUrl = 'jdbc:postgresql://<host>:<port>/<database>'
const jdbc = new JdbcDriver(ConnectionType.postgreSql, { jdbcUrl, username, password });

// For tibero connection
const jdbc = new JdbcDriver(ConnectionType.tibero, { host, port, database, username, password });

SQLite Connection

For SQLite connections, provide the path to the SQLite database file:

const path = '<db_path>';

// Set optional parameters
const minpoolsize = '<min_pool_size>'
const maxpoolsize = '<max_pool_size>'

const jdbc = new JdbcDriver(ConnectionType.sqlite, { path });

JDBC Connection using custom driver

 const jdbc = new JdbcDriver(ConnectionType.custom, {
        jars: 'sqlite-jdbc-3.7.2.jar', // local path of your jar file
        driverClass: 'org.sqlite.JDBC', // Driver class of your jar file
        jdbcUrl: 'jdbc:sqlite:/Users/jaynathray/Downloads/demo' // use jdbc url for connection
 const jdbc = new JdbcDriver(ConnectionType.custom, {
        jars: 'sqlite-jdbc-3.7.2.jar', // local path of your jar file
        driverClass: 'org.sqlite.JDBC', // Driver class of your jar file
        path: '/Users/jaynathray/Downloads/demo' // use path for connection

Basic Operations

Here are some basic operations you can perform using the node-jdbc-driver:

Check Driver Version

You can check the driver version using the following method:

const version = jdbc.get_version();

Count Example

To count the number of rows in a table:

const total = await jdbc.count('<table_name>');

Find Example

To find a single row based on a WHERE clause:

const row = await jdbc.find('<table_name>', '<where_clause>');

Find All Example

To retrieve all rows from a table:

const rows = await jdbc.findAll('<table_name>');

SQL Query Example

To execute a custom SQL query:

const results = await jdbc.sql('<sql_query>');

DDL Example

To execute Data Definition Language (DDL) queries:

const results = await jdbc.ddl('<sql_query>');

List Table Columns

To retrieve information about table columns:

const columns = await jdbc.get_columns('<table_name>');

Describe Table Properties

To get properties of a table:

const tblProperties = await jdbc.get_table_properties('<table_name>');
