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
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
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. -

Bootstrap Rating Input
Another plugin that eases the generation of rating stars for jQuery
This is another plugin that eases the generation of rating stars for jQuery and Bootstrap. The plugin transforms your number input into a hidden field and wraps it inside a div (Or a span with the inline option) along with the star icons that will catch your clicks and save the selected values into the hidden field. By doing this, the field still exist in your form and can be submitted or its current value read by jQuery normally. Any CSS class in addition to rating will be copied to the wrapper for further styling options. -

Britecharts
Composable Charting Library based on reusable D3.js components
Britecharts is a client-side reusable Charting Library based on D3.js v5 that offers easy and intuitive use of charts and components that can be composed together to create amazing visualizations. Britecharts components have been written in ES2016 with a Test Driven methodology, so they are fully tested, and we are committed to keeping them that way. The typical use of Britecharts involves creating a chart using its simple API, then rendering it on a container that has previously had data applied to it. All the components expose some common API methods like width, height, and margin. Additionally, each chart or component can expose specific methods you can find in the documentation. Britecharts components are distributed in UMD modules, each one exposing a D3.js component written with the Reusable API pattern. To use any of the Britecharts modules, you will need to require the chart in your JS file using AMD/CommonJS modules or adding a script tag with the src pointing to the file. -

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). -

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
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
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. -

Cancelable Async Flows
Cancelable Async Flows (CAF)
CAF (Cancelable Async Flows) is a small utility that brings cooperative cancellation to JavaScript async workflows. It wraps async generators or promise-returning functions so they can respond to a cancel signal and halt work early, preventing wasted CPU and stray side effects. The library encourages a disciplined pattern: pass a token into your task, periodically check it, and unwind gracefully when cancellation is requested. This approach avoids brittle timeouts and “fire-and-forget” leaks by making cancellation a first-class concern. CAF is framework-agnostic and pairs well with fetch, timers, or custom async primitives, giving you a consistent contract for stopping in-flight operations. The result is safer UI interactions and services that don’t keep doing work the user no longer needs. -

Chinese Poetry
The most comprehensive database of Chinese poetry
This repository is a curated collection of Chinese poems and poets organized into catalogs, metadata, and text representations suitable for research, creative and cultural use. It includes major dynastic corpora, such as Tang and Song poems, as well as biographical and categorization data. Each poem entry is structured with fields like author, dynasty, title, content, and sometimes annotations or alternate versions. Developers and scholars can build tools that query by author, era, keyword, or poetic form using the standardized data structure. Because the project is open, contributors improve metadata, correct text variants, and maintain consistency across classical collections. The corpus enables digital humanities, poetry apps, styling tools, and creative projects that intermix poems with translation, visualization, or musical settings.
