Node-oracle 4.0 has been released on https://npmjs.com/package/oracledb

*Top features: Querying and binding of named Oracle types; Oracle Advanced 
Queuing API; Oracle Implicit Results*

Querying and binding of named Oracle types and collections is now supported 
in node-oracledb 4.0.  It is easy to interact with user-defined and 
pre-supplied PL/SQL types, such as those in Oracle Spatial.  This is a big 
deal for Oracle Database users since PL/SQL usage is so common.  You can 
work with JavaScript objects in Node.js and bind them directly to PL/SQL 
parameters.  See Oracle Database Objects and Collections 
https://oracle.github.io/node-oracledb/doc/api.html#objects

Oracle Advanced Queuing is a highly configurable and scalable messaging 
feature of Oracle Database.  It has interfaces in various languages, 
letting you integrate multiple tools in your architecture to send and 
receive messages.  Node-oracledb 4.0 has an Advanced Queuing API.  You can 
send and receive String, Buffer or object messages.  This lets new classes 
of application be created in Node.js.  See Oracle Advanced Queuing 
https://oracle.github.io/node-oracledb/doc/api.html#aq

Oracle Implicit Results allow queries in PL/SQL to be returned to 
applications without requiring REF CURSORS or bind variables.  
Node-oracledb 4.0 supports Implicit Results, further enhancing the 
developer experience with working with PL/SQL packages.  See Implicit 
Results https://oracle.github.io/node-oracledb/doc/api.html#implicitresults

At the implementation level, node-oracledb 4 has been refactored to use the 
new N-API interface to Node.js.  This allows easier upgrades and installs.

Other features and fixes also landed in node-oracledb 4.0, see the 
CHANGELOG https://github.com/oracle/node-oracledb/blob/master/CHANGELOG.md

The release of node-oracledb 4.0 enhances the already-extensive support of 
Oracle Database features available to Node.js developer.  Node-oracledb has 
sophisticated connection and statement management, high availability 
features, and features such as networks encryption.  The driver is 
extensively tested and well documented.  Node-oracledb is a great 
development environment.
