MySQL Connector/Node.js 8.0.9 RC has been released

MySQL Connector/Node.js is a new Node.js driver for use with the X DevAPI. This release, v8.0.9, is the third development 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 5.7.12 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see

Functionality Added or Changed

  • Improved the UUID generation algorithm to implement the design improvements suggested in RFC 4122. Before the chance of duplicated values during a small time frame was too high. (Bug #26120588)
  • X DevAPI: In the process of refining the definition of the X DevAPI to cover the most relevant usage scenarios, the following API components have been removed from the X DevAPI implementation for Connector/Node.js:
    • API components that support session configurations, such as the SessionConfig and SessionConfigManager classes.
    • The mysqlx.config namespace and all methods of the namespace, save(), get(), list(), delete(), and more.
    • The createTable(), foreignKey(), dropTable(), createView(), dropView(), and alterView() methods from the Schema class.
  • The following methods were added:
    • Session.setSavePoint: accepts a name or generates one of the form connector-nodejs-{uuid}, and returns a Promise.
    • Session.releaseSavePoint: releases a specific savepoint.
    • Session.rollbackTo: rollbacks to a specified savepoint.
  • The createIndex() method was added to the Collection API.

Bugs Fixed

  • The expression parser used by the CRUD API was replaced with a new implementation written in pure JavaScript. This fixes several grammar related bugs. (Bug #26729768, Bug #26636956, Bug #25036336, Bug #23148246)
  • The CollectionFind.fields() method was updated to support flexible parameters to follow standard X DevAPI conventions. (Bug #22084545)

Enjoy and thanks for the support!
