Today Oracle released node-oracledb 1.0, the Node.js add-on to enable high performance Oracle Database applications.
Each month or so, since our first code bundle was pushed to GitHub earlier this year, we released a node-oracledb update with new functionality. The adoption has been exciting, with important applications already in production. This is our eighth release of node-oracledb and promises to be our best received so far.
The node-oracledb 1.0 add-on for Node.js supports standard and advanced features:
High Availability Features
Oracle enhances, maintains and supports node-oracledb via open source channels (i.e. GitHub), similar to Oracle Database drivers for other open source languages. The add-on is under the Apache 2.0 license.
Where to get node-oracledb
The Oracle Technology Network Node.js Developer Center has all the links and information you need to start using node-oracledb.
To jump start, follow these instructions to install node-oracledb.
Changes since the previous release
The major changes in node-oracledb 1.0 since the previous release are:
The Stream interface for CLOB and BLOB types was implemented, adding support for LOB queries, inserts, and PL/SQL LOB bind variables. As well as being needed for working with many legacy schemas, having LOB support lets application developers use Oracle Database 220.127.116.11's JSON data type without running into the length limitation of VARCHAR2 storage.
Customers have been contacting me what seems like every day, asking when LOB support would be available, and pleading for early access. Here it is, and it looks great. We'll be continuing to run load tests, benchmark it, and to enhance it.

Added support for binding DATE, TIMESTAMP, and TIMESTAMP WITH LOCAL TIME ZONE as
DATEto DML RETURNING (aka RETURNING INTO)
type. You can also bind these types as
The internal Oracle client character set is now always set to AL32UTF8. There's no longer a need to set it externally via NLS_LANG. A related bug with multibyte data reported by users was fixed by correcting the allocation of some internal buffers. Overall the NLS experience is much more consistent.
The test suite's and example database credentials can now be set via environment variables. A small change to help testing in automatically provisioned environments. Our test suite already has great coverage numbers, and will continue to be enhanced in future releases.
Bug fixes to node-oracledb. These are listed in the CHANGELOG.
Being an open source project in a dynamically changing environment, our statement of direction has been a brief, flexible goal: We are actively working on supporting Oracle Database features, and on functionality requests from users involved in the project. Our priority list is re-evaluated for each point release.
So now we have version 1.0, what next? This is just the start. There are plenty of important and interesting tasks in front of us. We will begin with a review of the project, from our development processes, the driver functionality, right through to distribution. This review will determine our next tasks. Hearing from users is crucial for prioritization, so don't hesitate to comment at GitHub.
Node.js is undergoing a surge of change at the moment, with the io.js re-merger, and the formation of the Node.js Foundation. As the merged Node.js code base stabilizes and the Foundation's LTS plans solidify, we will be able to be more formal about node-oracledb's schedule. We will work with Node.js and with partners to bring you the best experience. (On a technical note, the V2 release of the compatibility layer NAN was made in the last few days, too late for us to incorporate in node-oracledb 1.0. So, support of the latest, bleeding edge io.js will be in a future node-oracledb version.)
Let me wrap up this announcement by appreciating the growing node-oracledb community, particularly those who have contributed to node-oracledb with code, suggestions and discussions.
