Check server availability. about node-libcurl

If you use the Curl wrapper (async):

var Curl = require( 'node-libcurl' ).Curl,
    curl = new Curl(),
    url  = 'http://www.google.com',
    isAddressAvailable = false,
    statusCode;

curl.setOpt( Curl.option.URL, url );
curl.setOpt( Curl.option.CONNECTTIMEOUT, 5 ); // max of 5 seconds timeout to connect
curl.setOpt( Curl.option.FOLLOWLOCATION, true ); // follow redirects
curl.setOpt( Curl.option.NOBODY, true ); // just check the headers, ignore the response body

curl.on( 'end', function ( statusCode ) {

    isAddressAvailable = ( statusCode === 200 );
    this.close();
});

curl.on( 'error', function () {
    this.close();
});

curl.perform();

If you use the Easy handler (sync):

var Easy = require( 'node-libcurl' ).Easy,
    Curl = require( 'node-libcurl' ).Curl,
    url  = 'http://www.google.com',
    isAddressAvailable = false;

ch = new Easy();

ch.setOpt( Curl.option.URL, url );
ch.setOpt( Curl.option.CONNECTTIMEOUT, 5 ); // max of 5 seconds timeout to connect
ch.setOpt( Curl.option.FOLLOWLOCATION, true ); // follow redirects
ch.setOpt( Curl.option.NOBODY, true ); // just check the headers, ignore the response body

ret = ch.perform();
statusCode = ch.getInfo( Curl.info.RESPONSE_CODE );

ch.close();

isSiteAvailable = ( statusCode === 200 );
