Color Thief
Grab the color palette from an image using just Javascript
The Color Thief package includes multiple distribution files to support different environments and build processes. Gets the dominant color from the image. Color is returned as an array of three integers representing red, green, and blue values. When called in the browser, the image argument expects an HTML image element, not a URL. When run in Node, this argument expects a path to the image. quality is an optional argument that must be an Integer of value 1 or greater, and defaults to 10. The number determines how many pixels are skipped before the next one is sampled. We rarely need to sample every single pixel in the image to get good results. The bigger the number, the faster a value will be returned. Gets a palette from the image by clustering similar colors. The palette is returned as an array containing colors, each color itself an array of three integers. -

Detox
Gray box end-to-end testing and automation framework for mobile apps
High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. Detox tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user. The most difficult part of automated testing on mobile is the tip of the testing pyramid - E2E. The core problem with E2E tests is flakiness, tests are usually not deterministic. We believe the only way to tackle flakiness head on is by moving from black box testing to gray box testing. That's where Detox comes into play. Detox is built from the ground up to support React Native projects as well as pure native ones. Read the Getting Started Guide to get Detox running on your app in less than 10 minutes. We believe that the only way to address the core difficulties with mobile end-to-end testing is by rethinking some of the principles of the entire approach. -

Engine.IO
Transport-based cross-browser bi-directional communication layer
In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server. There are also several client implementation in other languages, which are maintained by the community. The client will try to establish a WebSocket connection if possible, and will fall back on HTTP long polling if not. WebSocket is a communication protocol which provides a full-duplex and low-latency channel between the server and the browser. -

Essential React
A minimal skeleton for building testable React apps using Babel
A minimal skeleton for building testable React apps using Babel. The design goals are to use fewer tools (no yeoman, gulp, bower, etc...) Babel 6 with Webpack and Hot Loader. Fast testing with mocked-out DOM. Import CSS files as class names. Separate smart and dumb components. No specific implementation of Flux or data fetching patterns. A core philosophy of this skeleton app is to keep the tooling to a minimum. For this reason, you can find all the commands in the scripts section of package.json. This leverages React Hot Loader to automatically start a local dev server and refresh file changes on the fly without reloading the page. It also automatically includes source maps, allowing you to browse code and set breakpoints on the original ES6 code. Build minified app for production using the production shortcut. -

FancySS
fancyss is a project for bypassing the Great Firewall (GFW)
Fancyss is a “scientific Internet access / bypassing censorship” toolkit targeted principally to Asus routers running AsusWRT or Merlin-based firmware. The project provides a plugin suite (with “software center” integration) so that home routers can run proxy or tunneling tools (e.g. V2Ray) to circumvent firewall or censorship (“GFW” in the Chinese context). Because it integrates into the router’s firmware environment, fancyss automates configuration, routing, and firewall rules to minimize manual tinkering. It supports multiple architectures and firmware versions, though some submodules or variants (e.g. “fancyss_hnd”) are optimized for specific chipsets. The project also maintains offline packages for constrained environments and hardware support lists. Many users adopt fancyss to turn relatively cheap consumer routers into censorship-resilient gateways, avoiding separate proxy appliances.
