How to use it?

Creating a bot instance

  var bot = require('nodemw');

  // pass configuration object
  var client = new bot({
      server: 'en.wikipedia.org',  // host name of MediaWiki-powered site
      path: '/w',                  // path to api.php script
      debug: false                // is more verbose when set to true
  });

  client.getArticle('foo', function(data) {
      // ...
  });

Config file

nodemw can use config files as well as objects directly provided to bot object constructor.

 // read config from external file
 var client = new bot('config.js');

Config file is a JSON-encoded object with the following fields (see /examples/config-DIST.js file):

{
      "server": "en.wikipedia.org",  // host name of MediaWiki-powered site
      "path": "/w",                  // path to api.php script
      "debug": false,                // is more verbose when set to true
      "username": "foo",             // account to be used when logIn is called (optional)
      "password": "bar",             // password to be used when logIn is called (optional)
      "userAgent": "Custom UA",      // define custom bot's user agent
      "concurrency": 5               // how many API requests can be run in parallel (defaults to 3)
}

Making direct API calls

nodemw allows you make direct calls to MediaWiki API (example querying Semantic MediaWiki API):

var bot = require('nodemw'),
  client = new bot({
		server: 'semantic-mediawiki.org',
		path: '/w'
	}),
	params = {
		action: 'ask',
		query: '[[Modification date::+]]|?Modification date|sort=Modification date|order=desc'
	};

client.api.call(params /* api.php parameters */, function(info /* processed query result */, next, data /* raw data */) {
	console.log(data && data.query && data.query.results);
});
