Node.js CI Coverage Status code style: prettier

MediaWiki API client written in node.js



Using npm

npm install nodemw

Or Download the latest stable version via GitHub.

Development version

git clone


  • HTTP requests are stored in the queue and performed in parallel with limited number of "threads" (i.e. there's no risk of flooding the server)
  • articles creation / edit / move / delete
  • file uploads (using given content or via provided URL)
  • Special:Log processing
  • listing articles in categories
  • and much more
  • getting claims from WikiData

Where it's used

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: "", // 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) {

  // ...

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": "",  // 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" : "",     // 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: "",
    path: "/w",
  params = {
    action: "ask",
      "[[Modification date::+]]|?Modification date|sort=Modification date|order=desc",
  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);
