Termux Desktop
Setup A Beautiful Desktop/GUI In Termux
Termux Desktop is a collection of dotfiles and scripts for setting up a graphical Linux-style desktop environment inside Termux on Android. It helps users turn a phone or tablet into a more complete desktop-like workspace without needing root access. The setup uses VNC so the desktop can be opened through a VNC client after installation. It includes an Openbox-based environment with visual themes, menus, app launchers, terminal tools, file management, browser access, and system applets. The project is especially useful for experimenting with coding, Linux tools, classic applications, and lightweight desktop workflows on Android hardware. Since the repository is archived and marked as unmaintained, it is best treated as a legacy reference setup rather than an actively supported Termux desktop solution. -

react-native-safe-area-context
A flexible way to handle safe area insets in JS. Also works on Android
A flexible way to handle safe areas, also works on Android and the Web! This library currently has experimental support for the new react-native architecture. Note that there will be breaking changes and only the latest version of react-native will be supported. This library has 2 important concepts, if you are familiar with React Context this is very similar. The SafeAreaProvider component is a View from where insets provided by Consumers are relative to. This means that if this view overlaps with any system elements (status bar, notches, etc.) these values will be provided to descendent consumers. Usually, you will have one provider at the top of your app. Consumers are components and hooks that allow using inset values provided by the nearest parent Provider. Values are always relative to a provider and not to these components. -

IBPCollectionViewCompositionalLayout
Backport of UICollectionViewCompositionalLayout to earlier iOS 12
IBPCollectionViewCompositionalLayout is a backport of Apple's UICollectionViewCompositionalLayout APIs for older iOS versions. It allows applications targeting iOS 12 to adopt the compositional layout model introduced with iOS 13. Developers can define complex collection views from items, groups, sections, and dimensional rules instead of writing extensive custom layout subclasses. The same approach can create lists, grids, mosaics, nested groups, banners, and independently scrolling sections. An interoperability file helps projects share layout code between systems using the native API and those using the backport. The library closely mirrors Apple's API so migration requires minimal conceptual changes. It was created to reduce duplicate layout code during the transition to newer UIKit versions. -

react-native-iap
react-native native module for In App Purchase.
react-native-iap will help you access the In-App purchases capabilities of your device on iOS, and Android (Play Store and Amazon). In order to initialize the native modules, call initConnection() early in the lifecycle of your application. This should be done at a top-level component as the library caches the native connection. Initializing just before you needed is discouraged as it incurs on a performance hit. Calling this method multiple times without ending the previous connection will result in an error. Not calling this method will cause other method calls to be rejected as a connection needs to be established ahead of time. You should not call initConnection and endConnection every time you need to interact with the library. This is considered an anti-pattern as it consumes more time, and resources and could lead to undesired side effects such as many callbacks. -

DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application. Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results on the web or in the Android demo app, both of which are available on Google Play. We’ll publish the iOS demo app shortly. The UI in the demo can be updated live: the sandbox connects to the demo app via web sockets. -

Popcorn Time for iOS
https://github.com/PopcornTimeTV/PopcornTimeTV
PopcornTimeTV was an Apple TV, iPhone and iPad application to torrent movies and tv shows for streaming. Since 2016, this project has grown exponentially - both in its user base and in its functionality. However, the team size has gone the other way. We went from having 13+ developers on the team to 1 developer and 1 designer, both of whom have lives and projects outside of Popcorn Time. We have decided that we have given our all to this project and it's time for us to move on to pursue greater things. There is no doubt that this comes with a heavy heart as we have learned so much from this project and watched it grow from this simple torrenting app that could only play 720p video, to what it is today. All that being said, we do not want this project to just die after we leave. The size of the project might be a bit daunting to an unseasoned developer but the app is extremely stable and packed with almost every feature you could need. -
