Where it's used

• Over 10k edits on Poznań Wiki as Pyrabot - scripts repository

First script

An example script can be found in /examples directory.

cd examples
node pagesInCategory.js

You can enter debug mode by setting DEBUG enviromental variable:

DEBUG=1 node examples/pagesInCategory.js

You can enter dry-run mode (all "write" operations like edits and uploads will be disabled) by setting DRY_RUN environmental variable (or dryRun entry in the config):

DRY_RUN=1 node examples/pagesInCategory.js

Running unit tests

npm test

How to use it?

Creating a bot instance

var bot = require("nodemw");

// pass configuration object
var client = new bot({
  protocol: "https", // Wikipedia now enforces HTTPS
  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 (err, data) {
  // error handling
  if (err) {
    console.error(err);
    return;
  }

  // ...
});

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):

{
      "protocol": "https",  // default to 'http'
      "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)
      "domain" : "auth.bar.net",     // domain 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 (
    err /* Error instance or null */,
    info /* processed query result */,
    next /* more results? */,
    data /* raw data */,
  ) {
    console.log(data && data.query && data.query.results);
  },
);

// Where is Saksun, Faroe Islands located?
const geo = await client.getEntityClaim(
  "Q928875" /* Saksun */,
  "P625" /* place location */,
);

// will give you the geolocation of the place
expect(geo[0].mainsnak.datavalue.value).toMatchObject({
  latitude: 62.248888888889,
  longitude: -7.1758333333333,
});

// When was Albert Einstein born?
const res = await client.getArticleClaims("Albert Einstein");

const dateOfBirth = res.P569[0].mainsnak.datavalue.value;
expect(dateOfBirth.time).toMatch(/1879-03-14/);

const dateOfDeath = res.P570[0].mainsnak.datavalue.value;
expect(dateOfDeath.time).toMatch(/1955-04-18/);

// interwiki links for a given artlice
