MWoffliner

MWoffliner is a tool for making a local offline HTML snapshot of any online MediaWiki instance. It goes through all online articles (or a selection if specified) and create the corresponding ZIM file. It has mainly been tested against Wikimedia projects like Wikipedia and Wiktionary --- but it should also work for any recent MediaWiki.

Read CONTRIBUTING.md to know more about MWoffliner development.

User Help is available in the for a a FAQ.

Features

  • Scrape with or without image thumbnail
  • Scrape with or without audio/video multimedia content
  • S3 cache (optional)
  • Image size optimiser / Webp converter

  • Specify additional/non-main namespaces to scrape

Run mwoffliner --help to get all the possible options.

Prerequisites

  • *NIX Operating System (GNU/Linux, macOS, ...)
  • Redis
  • NodeJS version 16 or greater
  • Libzim (On GNU/Linux & macOS we automatically download it)
  • Various build tools which are probably already installed on your machine (packages libjpeg-dev, libglu1, autoconf, automake, gcc on Debian/Ubuntu)

... and an online MediaWiki with its API available.

Usage

To install MWoffliner globally:

npm i -g mwoffliner

You might need to run this command with the sudo command, depending how your npm is configured.

npm permission checking can be a bit annoying for a newcomer. Please read the documentation carefully if you hit problems: https://docs.npmjs.com/cli/v7/using-npm/scripts#user

Then to run it:

mwoffliner --help

To install and run it locally:

npm i
npm run mwoffliner -- --help

To use MWoffliner with a S3 cache, you should provide a S3 URL like this:

--optimisationCacheUrl="https://wasabisys.com/?bucketName=my-bucket&keyId=my-key-id&secretAccessKey=my-sac"

API

MWoffliner provides also an API and therefore can be used as a NodeJS library. Here a stub example that could go in your index.mjs file:

import * as mwoffliner from 'mwoffliner';

const parameters = {
    mwUrl: "https://es.wikipedia.org",
    adminEmail: "[email protected]",
    verbose: true,
    format: "nopic",
    articleList: "./articleList"
};
mwoffliner.execute(parameters); // returns a Promise

GNU/Linux - Debian based distributions

Install NodeJS: Read https://nodejs.org/en/download/current/

Install Redis:

sudo apt-get install redis-server

Troubleshooting

Older GNU/Linux distributions and/or versions of Node.js might be shipped with a deprecated version of npm. Older versions of npm have incompatbilities with certain versions of Node.js and might simply fail to install mwoffliner package.

We recommend to use a recent version of npm. Recent versions can perfectly deal with older Node.js 10. Do install the packaged version of npm and then use it to install a newer version like:

sudo npm install --unsafe-perm -g npm

Don't forget to remove the packaged version of npm afterward.
