cordova-plugin-ionic-webview is a Cordova plugin that provides high-performance web views for hybrid mobile applications. On iOS, it replaces UIWebView with WKWebView for better performance and features. On Android, it uses the latest evergreen webview (Chrome-based). The plugin implements a local HTTP server to serve app assets via HTTP(S) URLs instead of file:// URLs, which is necessary due to webview security restrictions. It supports custom URL schemes (ionic://, http://, https://), HTML5 mode routing for single-page applications, service worker request handling, and provides JavaScript APIs for converting file paths to webview-accessible URLs. The architecture consists of platform-specific native implementations (Java for Android, Objective-C for iOS) with a common JavaScript interface through Cordova's plugin system.
