mediawiki-title

Mediawiki title normalization, that conforms to the normalization rules used in MediaWiki Core. In general, the page title is converted to the mediawiki DB key format by trimming spaces, replacing whitespace symbols to underscores and applying wiki-specific capitalization rules. The namespace name is converted to a localized canonical name.

TitleError

Kind: global exception class

• TitleError

TitleError should be considered an opaque exception class, which is thrown by the various methods in this library. It is exported so that it can be identified if caught by the caller.

SiteInfo : Object

Information about a wikimedia site required to make correct normalization. This information matches the format used by the PHP API response, however not all of the fields are required for library operation.

The list of required properties is documented here, others can be removed.

Kind: global typedef
Properties

| Name | Type | Description | | --- | --- | --- | | general | Object | General information about the site | | general.lang | string | Site language code. | | general.legaltitlechars | string | A perl-like regex for characters allowed in the page title. | | general.case | string | Whether to capitalize the first letter of the title. Could be obtained from the general section of the siteInfo php API response. | | namespaces | Object | Site namespaces info in the same format as returned by PHP api. | | namespacealiases | Object | Site namespace aliases in the same format as returned by PHP api. | | specialpagealiases | Object | Site special page aliases in the same format as returned by PHP api. |

Usage

The library synchronously returns a normalized title. Wiki-specific rules should be fetched from the MediaWiki API, and cached outside of the library. The description of the required properties is available in the SiteInfo object docs.

var result = Title.newFromText('some_title', {
    		general: {
        	lang: 'en',
        	legaltitlechars: " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~\\x80-\\xFF+",
        	case: 'first-letter'
    	},
	namespaces: {
		"0": {
			id: 0,
			case: "first-letter",
			content: "",
			"*": ""
			},
		}
});
console.log(result.getPrefixedDBKey());
