This is prototype mobile browser, which transforms Muusikoiden.net into a fully fledged mobile application.
The mobile application doesn't save or send the information anywhere, everything happens inside the mobile application. All pages are viewed inside WebView components, with injecting JavaScript which transforms the legacy table-folded HTML structure into modern flex/block layout, which nicely works on mobile devices.
Each section hides unrelevant information from the page. For example in MarketplaceScreen, component responsible on rendering the center, MarketplaceContent, hides top header, left menu and product categories. When pressing hamburger button top right, MarketplaceMenu pops from bottom - which displays a page which has everything but product categories hidden.
Each WebView also hijack links by placing document level listener or target specific links. This is done so that for example links to images can be rendered with with zoomable/pannable react-native-image-zoom-viewer image viewer component. Hijacked links are targeted into main content WebView, for example links hijacked in menu open in main content WebView instead.
Common parts of the hiding is implemented in commonInjectedFunctions part, which is shared in all WebView -pages components.
The mobile app has been developed with Expo, however, it's mainly a regular React Native application (no Expo-specific things used, however converting would need to dismantle Expo of course).
The application is licensed under MIT license.
