basex - A BaseX client for node.js

===========================

This is a BaseX client for Node.js. It uses the client interface via a socket connection to the BaseX server.

BaseX is a very light-weight, high-performance and scalable XML Database engine and XPath/XQuery 3.0 Processor, including full support for the W3C Update and Full Text extensions. Built as a lightweight Java server, BaseX also supports XSLT, Webdav and RestXQ.

Installing the BaseX Node client

To install with npm:

npm install basex

	$ mkdir myproject
	cd myproject
	$ npm install basex
	[email protected] ./node_modules/basex 

Once BaseX is installed and the BaseX server is running, test it.

	$ cd examples/
	$ node Example.js 
	milliseconds: 0
	{ result: '1 2 3 4 5 6 7 8 9 10',
	  info: '\nQuery executed in 0.38 ms.\n' }
	end
	close

Installing BaseX

1. Java is required
2. Download and install BaseX (tested against versions 9.6,8.6)
3. Run basexserver -S
