### type

> **type**: `string` & `object` | `"specialpage"` | `"editor"` | `"wikifamily"` | `"parserhook"` | `"variable"` | `"media"` | `"antispam"` | `"skin"` | `"api"` | `"other"`

Defined in: [core/query/siteinfo.ts:470](https://github.com/BearBin1215/types-mediawiki-response/blob/c1e25ea2ef2684b43c79e05d6e0dd36e33fbc9a3/src/core/query/siteinfo.ts#L470)

Component class. The names MediaWiki has display labels for are
`specialpage`, `editor`, `wikifamily`, `parserhook`, `variable`, `media`,
`antispam`, `skin`, `api` and `other`, but the value is never validated
against them: a component declares its own `type` in `extension.json`,
`$wgExtensionCredits` entries pass through as written, and the
`ExtensionTypes` hook can add further names — **open union**.
