Dear MySQL users,

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.18, is a maintenance release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see for details) or from

To learn more about how to write applications using the X DevAPI, see
For more information about how the X DevAPI is implemented in MySQL
Connector/Node.js, and its usage, see

Please note that the X DevAPI requires at least MySQL Server version
8.0 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see

Changes in MySQL Connector/Node.js 8.0.18 (2019-10-14, General

Functionality Added or Changed

     * Implemented the X DevAPI cursor model, which includes
       adding methods such as fetchOne(), fetchAll(),
       getColumns(), hasData(), and nextResult(). For additional
       details, see the X DevAPI documentation about Working
       with Result Sets
       Previously, handling result set data or metadata required
       specific callback functions when calling execute(). With
       this new interface, the connector automatically switches
       to this new pull-based cursor model if these callback
       functions are not provided.

     * Improved Collection.getOne() performance by making the
       underlying lookup expression to only parse once, and
       having subsequent Collection.getOne() calls utilize
       server-side prepared statements.

     * Added support to generate test coverage reports by
       running the likes of npm run coverage; see the bundled for details and requirements. This was
       added to help users contribute patches.

     * Added linter check support to help enforce coding style
       and convention rules for new contributions by running the
       likes of npm run linter; see the bundled
       for details.

Bugs Fixed

     * Added support for assigning Node.js Buffer values to
       expression or SQL query placeholders. (Bug #30163003, Bug

     * MySQL column binary values (such as BLOB, BINARY, and
       VARBINARY) can now convert to proper Node.js Buffer
       instances. (Bug #30162858, Bug #96478)

     * Inserting a raw Node.js Buffer value into MySQL BLOB
       field resulted in an error as the content_type was
       improperly set; it's now handled as a raw byte string by
       the X Plugin. (Bug #30158425)

     * The padding characters used for fixed-lengthed columns
       now map to the collation code provided by the column
       metadata; previously it was based on the JavaScript
       native type of the values. (Bug #30030159)
