BottomBar
Custom view component that mimics the new Material Design pattern
A custom view component that mimics the new Material Design Bottom Navigation pattern. You can add items by writing a XML resource file. The icons must be fully opaque, solid black color, 24dp and with no padding. For example, with Android Asset Studio Generic Icon generator, select "TRIM" and make sure the padding is 0dp. Define your tabs in an XML resource file. Then, add the BottomBar to your layout and give it a resource id for your tabs xml file. By default, the tabs don't do anything unless you listen for selection events and do something when the tabs are selected. This new version has cleaner code and better APIs. No more unnecessary stuff or spaghetti mess. Now the look, feel and behavior is defined in XML, as it should be. No more nasty regressions, thanks to the automated tests. Everything is a little different compared to earlier, but it's for the greater good! -

Bowser
Bowser is a browser detector
A small, fast and rich-API browser/platform/engine detector for both browser and node. The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers. Version 2.0 has drastically changed the API. All available methods are on the docs page. Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. You could want to filter some particular browsers to provide any special support for them or make any workarounds. Settings for any particular OS or platform has more priority and redefines settings of standalone browsers. Thus, you can define OS or platform-specific rules and they will have more priority in the end. More of API and possibilities you will find in the docs folder. -

Bricks.js
A blazing fast masonry layout generator for fixed width elements
Bricks capitalizes on batched reading of layout properties for blazing fastpacking time, no matter how many items. Bricks was developed with a modern JavaScript workflow in mind.

Using your instance, you can enable and disable the resize handler, add and remove event handlers, accommodate dynamically added elements, etc. Bricks instances are extended with Knot.js, a browser-based event emitter. Use the event emitter syntax to add and remove handlers for the events emitted by the API methods. Bricks depends on the browser APIs ES5 array methods, forEach, map, indexOf, requestAnimationFrame, and matchMedia. -

Fastbot-Android Open Source Handbook
Testing tool for modeling GUI transitions
Fastbot_Android (Fastbot 2.0) is a model-based automated testing tool by ByteDance designed to discover stability or usability issues in Android apps by modeling GUI transitions rather than relying purely on random interactions. It blends machine learning and reinforcement-learning approaches to build a transition graph of UI states and use that model to intelligently explore possible user interactions — aiming to replicate more human-like usage patterns and uncover hidden bugs, crashes, or edge cases. Compared to traditional random-input tools (like Monkey), Fastbot supports much faster action insertion (up to ~12 actions per second) and can handle a variety of Android OS versions (from older through modern, including customized OS variants). It also supports model reuse: once a model of an app’s GUI transitions is built, subsequent testing sessions can reuse the model to speed up testing or target known risky paths. -
