# basex - A BaseX client for node.js  
===========================

This is a [BaseX](http://basex.org/) client for Node.js. 
It uses the [client interface](http://docs.basex.org/wiki/Server_Protocol)
 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
[![Npm package monthly downloads](https://badgen.net/npm/dm/@quodatum/basex)](https://npmjs.com/package/@quodatum/basex)

To install with npm:

`npm install @quodatum/basex`

```bash
	$ mkdir myproject
	cd myproject
	$ npm install @quodatum/basex
	@quodatum/basex@1.0.0 ./node_modules/@quodatum/basex 
```

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

```bash
	$ 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
