Usage

Client-side (web browser)

1. Include

   <script type="text/javascript" src="Cypher.min.js"></script>

2. Use

   var options = {
   
   	// Default will run as Web Worker, i.e. runInWebWorker = true if not specified
   	// Set runInWebWorker to false to run in same thread as main page javascript
   	runInWebWorker: true,
   
   	// Proxy for xmlhttprequest to avoid CORS. This is optional. If not provided
   	// will attempt to download from given URL directly which might give error
   	// Access denied for URL resource due to "Cross-Origin Request Blocked"
   	// The data download proxy must take one GET parameter, u, which is the URL to download
   	// and must return the data from the URL to download. 
   	// Also it should add the "Access-Control-Allow-Origin: *" http header to the response
   	// if the proxy is not served from same url as Cypher.js script is run from
   	dataDownloadProxy: "http://proxy_url?u="
   
   };
   var cypher = new Cypher(options);
   
   var query = 'merge (n:Test{what:"Hello World"}) return n';
   
   cypher.execute(
   	query,
   	function(results) {
   		console.log(results);
   	},
   	function(errorText) {
   		console.log(errorText);
   	}
   );
   

Node.js

// Dependency to https package
var https = require("https");

var Cypher = require("Cypher.min.js").Cypher;

var options = {

	// In Node.js the runInWebWorker option must be set to false
	// Web Workers are not supported in Node.js
	runInWebWorker: false,

	// In Node.js a proxy is not needed
	dataDownloadProxy: null

};
var cypher = new Cypher(true);

cypher.execute(
	'unwind range(0,10) as item return item',
	function(results) {
		console.log(JSON.stringify(results));
	},
	function(error) {
		console.log(error);
	}
);
