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

## Prerequisites
- *NIX Operating System (GNU/Linux, macOS, ...)
- [Redis](https://redis.io/)
- [NodeJS](https://nodejs.org/en/) version 22 (we support only one single Node.JS version, other versions might work or not)
- [Libzim](https://github.com/openzim/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 latest released MWoffliner version from NPM repo (use `-g` to install globally, not only in current folder):
```bash
npm i -g mwoffliner
```
> [!WARNING]
> Note that you might need to run this command with the `sudo` command, depending
how your `npm` / OS 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 you can run the scraper:
```bash
mwoffliner --help
```
To use MWoffliner with a S3 cache, you should provide a S3 URL like
this:
```bash
--optimisationCacheUrl="https://wasabisys.com/?bucketName=my-bucket&keyId=my-key-id&secretAccessKey=my-sac"
```
## Contribute
If you've retrieved mwoffliner source code (e.g. with a git clone of our repo), you can then install and run it locally (including with your local modifications):
```bash
npm i
npm run mwoffliner -- --help
```
Detailed [contribution documentation and guidelines](CONTRIBUTING.md) are available.
## 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:
```javascript
import * as mwoffliner from 'mwoffliner';
const parameters = {
mwUrl: "https://es.wikipedia.org",
adminEmail: "foo@bar.net",
verbose: true,
format: "nopic",
articleList: "./articleList"
};
mwoffliner.execute(parameters); // returns a Promise
```
