API docs

• init(callback[, options]) - Initializes the library.

  • callback(status): A callback function will be called upon initialization with status indicating if initialization is successfull.
  • options: This optional options object will passed to phantomjs-node's create function. Additionally following fields are available.
    • verbosity: Enable verbose log (default false).
    • port: To include js files to the page, nodalyzer opens a http connection on specified port. (default 8125). This is a workaround since phantomjs-node doesn't support includeJs with libraryPath.

• get(url, callback) - Opens the url/site and returns technologies detected.

  • url: url
  • callback(err, response): A callback function will be called with error and response object. In case of an error, err will be an instance of Error. In case of success, err will be null and response will contain following fields:
    • apps: Array of apps with following properties.
      • name: Name of the app
      • category: Category

• close([force]) - This will wait for the pending urls to complete and then exits the phantom instance and other dependencies. For sample usage, refer to previous example.

  • force: If force is set, exits without waiting for pending urls to complete.

An example usage of above APIs is shown below.

var nodalyzer = require('nodalyzer');

nodalyzer.init(function (status) {
	if (!status) { return; }
	nodalyzer.get('http://www.github.com/', function (err, response) {
      if (err) { throw err; }
      response.apps.forEach(function (app) {
          console.log(app);
      });
	});
    nodalyzer.close();
});
