WK Cache Clear

WKCacheClear selectively clears the WkWebView cache for Cordova 9 running on iOS 9 or above.

Derived from Anrip Wong's CacheClear plugin https://github.com/anrip/cordova-plugin-cache-clear. This plugin was rewritten to specifically support WkWebView on iOS, whose cache clearing mechanics differ from UIWebView. Android support was not considered, since WkWebView is specific to iOS.

Installation

Using the standard Cordova CLI:

cordova plugin add https://github.com/mgatto/cordova-plugin-wkwebview-clearcache.git

Usage

document.addEventListener('deviceready', function() {
    window.WkCacheClear({domain: 'example.com', delete: ['cookies','assets']}, (msg) => '', (error) => '');
});

Options

• domain: Required. A domain name string: "example.com" or "sub.domain.com". Omit slashes and protocols, like "http:". Required, since the user may not like cookies for other sites being deleted in Safari

• delete: Optional. an array of plain-text aliases for WkWebSiteDataType constants:

  Supported:

  • (included automatically) WKWebsiteDataTypeMemoryCache
  • (included automatically) WKWebsiteDataTypeOfflineWebApplicationCache
  • cookies => WKWebsiteDataTypeCookies
  • assets => WKWebsiteDataTypeDiskCache (HTML, JS and image files cached from the Cordova bundle)

  Unsupported:

  • WKWebsiteDataTypeLocalStorage
  • WKWebsiteDataTypeSessionStorage
  • WKWebsiteDataTypeIndexedDBDatabases
