    Backbone

    Backbone

    Give your JS app some Backbone with models, views, and collections

    Backbone is a lightweight JavaScript library (sometimes described as a micro-framework) created by Jeremy Ashkenas that adds structure to JavaScript-heavy applications by providing models, views, collections, events and routing tied to RESTful JSON services. Its main philosophy is to provide the minimal set of primitives to organise your client-side code — models for data, collections for groups of models, views for UI interactions, and routers for state/URL management — without prescribing a full rigid framework. Because of this minimalism, Backbone integrates easily into existing applications and is flexible rather than opinionated, making it popular in the era before heavier single-page frameworks dominated. It helps developers avoid "spaghetti code" by separating concerns and centralising data-bindings and event flows. Even though newer frameworks have largely overtaken it in popularity, Backbone remains a valuable historical and educational reference.

    Basscss

    Basscss

    Low-level CSS Toolkit, the original Functional/Utility/Atomic CSS

    Using clear, humanized naming conventions, Basscss is quick to internalize and easy to reason about while speeding up development time with more scalable, more readable code. Things behave exactly as expected with immutable utilities and styles that do one thing well to help prevent common pitfalls with CSS. Reusable, interoperable styles work like building blocks to lay the foundation for any stylesheet and can be mixed and matched in any number of combinations. Basscss strikes a balance between consistency and flexibility to allow for rapid prototyping and quick iterative changes when designing in the browser. Basscss provides lightweight, performant styles and flexible utilities to design for any device and to help reduce boilerplate in stylesheets. Modular and customizable typography and layout styles don’t dictate what things should look like and play well with other stylesheets and frameworks.

    Bluebird

    Bluebird

    Full featured promise library with unmatched performance

    Bluebird is a fully featured promise library with focus on innovative features and performance. Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself. When using script tags the global variables Promise and P (alias for Promise) become available. Bluebird runs on a wide variety of browsers including older versions. Synchronous inspection allows you to retrieve the fulfillment value of an already fulfilled promise or the rejection reason of an already rejected promise synchronously. The default approach of bluebird is to immediately log the stack trace when there is an unhandled rejection.

Any CSS class in addition to rating will be copied to the wrapper for further styling options.

    Bootstrap Table

    Bootstrap Table

    Extended table to integration with some of the most widely used CSS

    Include Bootstrap Table source CSS and JavaScript files via npm or yarn. When you only need to include Bootstrap Table’s compiled CSS or JS, use UNPKG. Download Bootstrap Table to get the compiled CSS and JavaScript, source code, or include it with your favorite package managers like npm, bowser, and more. Install and manage Bootstrap table’s CSS, JavaScript, locales, and extensions using npm. Install and manage Bootstrap table’s CSS, JavaScript, locales, and extensions using bower. Be sure to have your pages set up with the latest design and development standards. That means using an HTML5 doctype and including a viewport meta tag for proper responsive behaviors. Bootstrap Table requires the use of the HTML5 doctype. Without it, you’ll see some funky incomplete styling, but including it shouldn’t cause any considerable hiccups.

    Buckets

    Buckets

    A complete, fully tested and documented data structure library

    A complete fully tested and documented data structure library written in pure JavaScript. Buckets also includes several functions for manipulating arrays. A bag is a special kind of set in which members are allowed to appear more than once. Binary search trees keep their elements in sorted order, so that lookup and other operations can use the principle of binary search. Dictionaries map keys to values, each key can map to at most one value. A heap is a binary tree that maintains the heap property. Every node is less than or equal to each of its children. A linked list is a sequence of items arranged one after another. A multi dictionary is a special kind of dictionary that holds multiple values against each key. In a priority queue, each element is associated with a "priority", and elements are dequeued in the highest-priority-first order (the elements with the highest priority are dequeued first).

    Buttons 2.0

    Buttons 2.0

    A CSS button library built using Sass and Compass

    Buttons is a highly customizable production ready mobile web and desktop css button library. Buttons is a free open source project created using Sass. View the showcase demo to see the buttons in action. The showcase provides a full list of examples along with code snippets to speed up development. If you're using Bower you can run bower install Buttons. Buttons styles are now independent (ex. button-flat, button-3d, etc.). You can apply these styles and they will automatically pick up the color attached to the button (ex. button-primary button-3d). Button colors are now completely independent (ex. button-primary). We no longer have classes like button-flat-primary, so to achieve this you now simply add button-flat button-primary. To edit Buttons simply change values within the _options.scss file. After you make your edits recompile your sass file and your changes will get processed.

    BypassAntiVirus

    BypassAntiVirus

    The remote control no-kill series of articles and supporting tools

    BypassAntiVirus is a security-research archive focused on studying how antivirus products detect remote-access payloads and related executable techniques. It contains a long series of articles documenting historical evasion approaches, tool comparisons, implementation experiments, and detection-rate testing. The material examines how changes in packaging, compilation, trusted system components, and execution techniques can affect antivirus visibility. Numerous security tools and research examples are collected alongside the written material. Results were historically compared against multiple antivirus engines to illustrate differences in detection behavior. Because the repository concerns defensive bypass techniques that can be misused, it is most appropriate for authorized red-team research, malware analysis, and defensive detection engineering.

    C3.js

    C3.js

    A D3-based reusable chart library

    C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by bindto because MutationObserver is not called in that case.

    CSSgram

    CSSgram

    CSS library for Instagram filters

    Simply put, CSSgram is a library for editing your images with Instagram-like filters directly using CSS. What we're doing is adding filters to the images, as well as applying color and/or gradient overlays via various blending techniques to mimic filter effects. This means less manual image processing and more fun filter effects on the web! We are using pseudo-elements (i.e. :before and :after) to create the filter effects, so you must apply these filters on a containing element (i.e. not a content-block like <img>. The recommendation is to wrap your images in a <figure> tag. If you use custom naming in your CSS architecture, you can add the .scss files for the provided styles within your project and then @extend the filter effects within your style definitions. Mixins allow for multiple filter arguments to be passed into your classes. This is useful for if you want to add filters in addition to the ones provided (i.e. add a blur).

    Callbag basics

    Callbag basics

    Tiny and fast reactive/iterable programming library

    Callbag Basics is an open-source JavaScript library that provides reusable utilities for reactive and iterable programming using the Callbag specification. It unifies push-based event streams and pull-based iterables through a simple communication protocol. Developers can create data sources from arrays, promises, browser events, and intervals. Common operators perform transformations such as mapping, filtering, scanning, merging, and flattening sequences. The same operators can work with synchronous iterables and asynchronous event sources. A pipe utility combines multiple operations into readable functional pipelines. The library emphasizes small bundle sizes, high performance, and extensibility through independent functions. Its modular architecture allows developers to import only the functionality they need.
