The node-oracledb add-on for Node.js powers high performance Oracle Database applications. Applications can be written in TypeScript, or directly in JavaScript.
Use node-oracledb 6.9.0 to connect Node.js 14.17, or later, to Oracle Database. Older versions of node-oracledb may work with older versions of Node.js.
Node-oracledb supports basic and advanced features of Oracle Database and Oracle Client. See the homepage for a list.
The node-oracledb module is open source and maintained by Oracle Corp. It is stable, well documented, and has a comprehensive test suite.
Run npm install oracledb
See Getting Started with Node-oracledb and Quick Start Node-oracledb Installation.
-
Node.js versions 14.17 and later.
Pre-built packages are available on npm and other mirror repositories.
Source code is also available.
Previous versions of node-oracledb supported older Node.js versions.
-
Oracle Client libraries are optional starting from node-oracledb 6.0. Older versions of node-oracledb require Oracle Client libraries.
Thin mode: By default node-oracledb (from version 6.0 onwards) runs in a 'Thin' mode which connects directly to Oracle Database.
Thick mode: Some advanced Oracle Database functionality is currently only available when optional Oracle Client libraries are loaded by node-oracledb. Libraries are available in the free Oracle Instant Client packages. Node-oracledb can use Oracle Client libraries 11.2 through 23ai.
-
Oracle Database
Thin mode: Oracle Database 12.1 (or later) is required.
Thick mode: Oracle Database 9.2 (or later) is required, depending on the Oracle Client library version. Oracle Database's standard client-server version interoperability allows connection to both older and newer databases. For example when node-oracledb uses Oracle Client 19c libraries, then it can connect to Oracle Database 11.2 or later.
