The MarkLogic Client API for Node.js provides access to the MarkLogic database from Node.js.

This branch provides the work in progress for the Early Access Release 3 of the MarkLogic Node.js API.

Please register at the MarkLogic Early Access website and then follow the tutorial instructions:

http://ea.marklogic.com/features/node-js-client-api/

The instructions describe:

• installing the MarkLogic database and setting up an admin user
• cloning this repository to set up the API
• working through some initial examples to get familiar with the API

For more detail about the API, use the documentation login from the Early Access to view the reference documentation:

http://docs-ea.marklogic.com/jsdoc/index.html

After installing the dependencies including gulp, you can also build the documentation locally from the root directory of the marklogic package:

gulp doc

The documentation should be produced in the doc subdirectory.

To set up the REST users for the examples, execute the following command in the root directory for the marklogic package:

node etc/users-setup.js

Then, load the sample data:

node examples/before-load.js

You can then execute any of the examples in the examples subdirectory from the root directory for the marklogic package.

To set up the test database and REST server, execute the following command in the root directory for the marklogic package:

node etc/test-setup.js

To tear down the test database and REST server, execute

node etc/test-teardown.js

The MarkLogic Node.js Client API has not yet undergone performance or stress testing. The API should not be used in production in EA3. The interface may change before the initial release.

The MarkLogic Node.js Client API is maintained by MarkLogic Engineering. It is designed for use in production applications with MarkLogic Server. Everyone is encouraged to file bug reports, feature requests, and pull requests through GitHub. This input is critical and will be carefully considered, but we can’t promise a specific resolution or timeframe for any request. In addition, MarkLogic provides technical support for release tags of the Node Client API to licensed customers under the terms outlined in the Support Handbook.
