    Tauri

    Tauri

    Build smaller, faster, and more secure desktop applications

    Tauri is an open-source framework for building lightweight and high-performance desktop and mobile applications using web technologies. It allows developers to create user interfaces with HTML, CSS, and JavaScript while using Rust for the backend logic. By leveraging the operating system’s native WebView instead of bundling a full browser, Tauri produces significantly smaller and more efficient application binaries. The framework supports multiple front-end frameworks such as React, Vue, Svelte, and others that compile to web technologies. Tauri provides a secure bridge between the frontend and the Rust backend, enabling native functionality while maintaining strong security practices. With cross-platform support, developers can build applications that run on Windows, macOS, Linux, Android, and iOS.

    React Native Navigation

    React Native Navigation

    A complete native navigation solution for React Native

    React Native Navigation is a module, dependent on and intended to be used alongside React Native, so some experience with it and knowledge of core concepts is required. We also assume you are working on a Mac with XCode and Android Studio installed and setup. You can also make it work in a Linux distribution, of course, but in that case bear in mind that some sections of the docs that deal with iOS might not be relevant to you. When your app is launched for the first time, the bundle is parsed and executed. At this point you need to display your UI. To do so, listen to the appLaunched event and call Navigation.setRoot when that event is received. When your app is launched, RN makes sure JS context (which is what enables you to execute JavaScript code) is running. There are quite a few differences between iOS and Android in this regard.

    Reflex Platform

    Reflex Platform

    A curated package set and set of tools that let you build Haskell

    Reflex Platform is a curated package set and set of tools that let you build Haskell packages so they can run on a variety of platforms. Reflex Platform is built on top of the nix package manager. The core packages in Reflex Platform are known to work together and are tested together. the core packages in Reflex Platform are cached so you can download prebuilt binaries from the public cache instead of building from scratch. Nix locks down dependencies even outside the Haskell ecosystem (e.g., versions of C libraries that the Haskell code depends on), so you get completely reproducible builds. Reflex Platform is designed to target iOS and Android on mobile, JavaScript on the web, and Linux and macOS on desktop. It's Haskell, everywhere. Reflex Platform comes packaged with tools to make development easier, like a hoogle server that you can run locally to look up definitions.

    Buck

    Buck

    Build system that encourages the creation of small, reusable modules

    Buck is a build system developed and used by Facebook. It encourages the creation of small, reusable modules consisting of code and resources, and supports a variety of languages on many platforms. Buck builds independent artifacts in parallel to take advantage of multiple cores on your machine. Further, it reduces incremental build times by keeping track of unchanged modules so that the minimal set of modules is rebuilt. Buck only uses the declared inputs, which means everybody gets the same results. Buck looks at the contents of your inputs, not their timestamps to figure out what needs to be built. As a result, incremental builds should always be correct, so there's no need to perform a clean build. With buck query, you can better understand your dependencies and what is required to build your product. With buck project, your project can be better understood by your IDE, making you and your team more productive.

    Hippy

    Hippy

    Tool to build cross-platform and high-performance awesome apps

    Hippy is a cross-platform development framework, aiming to help developers write once, run on three platforms(iOS, Android and Web). Hippy is quite friendly to Web developers, especially who are familiar with React or Vue. With Hippy, developers are able to create the cross platform app easily. Hippy is now applied in 27+ Tencent apps such as Mobile QQ, Mobile QQ Browser, Tencent Video App, QQ Music App, Tencent News, reaching hundreds of millions of ordinary users. For Android, we recommend using the real cellphone for better develop experience, because Hippy is using X5 JS engine which can't support x86 simulator, as well as ARM simulator has a low performance. For iOS, we recommend to use iOS simulator when first try. However, you can change the Xcode configuration to install the app to iPhone if you are an iOS expert.

    Ratchet

    Ratchet

    Build mobile apps with simple HTML, CSS, and JavaScript components

    Ratchet is designed to respond to touch events from a mobile device. Enable touch event emulation in Chrome (found in the overrides tab in the web inspector preferences). Use a JavaScript library like fingerblast.js to emulate touch events (ideally only loaded from desktop devices). Ratchet is downloadable in two forms, within which you'll find directories and files, logically grouping common resources and providing both compiled and minified variations. The most basic form of Ratchet is the grouping of the precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (ratchet.*), as well as compiled and minified CSS and JS (ratchet.min.*). The Ratchicon fonts are included, as are the Android and iOS platform themes. The Ratchet source code download includes the precompiled CSS, JavaScript, and font assets. Provides design patterns that serve as basic building blocks.

    ReactXP

    ReactXP

    Library for cross-platform app development

    ReactXP builds on the popular React JS and React Native frameworks. Share most of your code between the web, iOS, Android, and Windows. Create great-looking, responsive web pages and mobile apps that feel native. With React and React Native, your web app can share most its logic with your iOS and Android apps, but the view layer needs to be implemented separately for each platform. We have taken this a step further and developed a thin cross-platform layer we call ReactXP. If you write your app to this abstraction, you can share your view definitions, styles and animations across multiple target platforms. Of course, you can still provide platform-specific UI variants, but this can be done selectively where desired. ReactXP is designed with cross-platform development in mind. In general, it exposes APIs, components, props, styles and animation parameters that are implemented in a consistent way across React JS (HTML) and React Native for iOS and Android.

    libgit2

    libgit2

    A cross-platform, portable, linkable Git implementation library

    libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings. Libgit2 is developed with CMake, and this is be the easiest way to build a binary from the source. The CMake build system provides lots of options to configure the libgit2 build for your particular needs. It’s highly recommended that you build libgit2 as a static library for Xcode projects to simplify distribution significantly. libgit2 is used for powering Git GUI clients, such as gmaster and GitKraken and on Git hosting providers such as GitLab, Azure, GitHub, DevOps, among others. By clicking "merge pull request", we perform the merge. It is licensed under the GPLv2 license, so you can link it in its unmodified state with any type of software without releasing its source code.
