A simple way to access MediaWiki API via JavaScript with wikitext parser. This is basically a modern syntax version of CeJS MediaWiki module. For example, using async functions.
- Read / edit pages.
- Get list of categorymembers, pages transclude specified template, and more...
- Auto-limited editing rate.
- Parse wikitext / pages. You may modify parts of the wikitext, then regenerate the page just using .toString(). See wikitext parser examples.
This is a nodejs module. Please install node.js first.
npm install wikiapiHere lists some examples of this module.
- Login to wiki site
- Get page data and parse the wikitext
- Listen to page modification
- Edit page
- Edit multiple pages
- Get category tree
- Get wikidata
- Upload file / media
- Download file / media
- Move page
// Load Wikiapi module

By default, the library will use the user agent get_URL_node.default_user_agent set in Ajax.js. If you want to set another user agent, you can change CeL.wiki.query.get_URL_options listed in query.js:
CeL.wiki.query.get_URL_options.headers['User-Agent'] = 'testbot/1.0';| Platform | support |

| Windows | ✔️ |
| macOS | ✔️ |
