Google Search Appliance Node.js Proxy

Node.js GSA (Google Search Appliance) Proxy

The proxy should be available on the npm repository. So you should simply install it using: npm install node-gsaproxy

The proxy supports multiple instances, so you can create threaded applications using multiple proxy instances.

First create an instance using:

var GSAProxy = require('gsaproxy');  
var gsaProxy = new GSAProxy();
var gsaProxy = new GSAProxy(basepath, parameters);

The basepath specifies protocol, path and port of your gsa.
For Example:

http://mygsa.de/search?

The parameters object defines the parameters.
For Example:

{  
    q: 'mysearchstring',  
    site: 'mycollection',  
    [...]  
}

You have the opportunity to change the parameters after you have created the GSAProxy instance.

If you want to query multiple gsas with the same GSAProxy instance you have can change the basepath afterwards.

var gsaProxy = new GSAProxy('http://gsa1.de/');
[...]
gsaProxy.setBasepath('http://gsa2.de/');

The parameters you set are extended with the default parameters. So you do not have to specifiy all parameters yourself.

var gsaProxy = new GSAProxy('http://gsa1.de/', {
    site: 'collection1'
});
console.log(gsaProxy.getParameters());
 
gsaProxy.setParameters({
    client: 'collection1'
});
console.log(gsaProxy.getParameters());
 
console.log(gsaProxy.getParameter('q'));
gsaProxy.setParameter('q', 'mysearchstring');
console.log(gsaProxy.getParameter('q'));
gsaProxy.execute(function(err, res) {
    if (err) throw err;
    console.log(res);
});
gsaProxy.executeJson(function(err, res) {
    if (err) throw err;
    console.log(JSON.stringify(res));
});
gsaProxy.executeXslt(XSL_FILE_PATH_OR_XSL_AS_STRING, function(err, res) {
    if (err) throw err;
    console.log(res);
}, PARAMETERS);

Using the PARAMETERS parameter, you can pass some arguments to the xslt processor for usage in the xsl stylesheet.
The format of should be like this:

var PARAMETERS = [
    'key1', 'value1',
    'key2', 'value2'
];
