    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    Immutable.js

    Immutable.js

    Immutable collections for JavaScript

    Immutable.js offers a collection of Persistent Immutable data structures for JavaScript. Immutable data is unchangeable once created, which makes application development so much simpler. There’s no defensive copying, and you get advanced memoization and change detection techniques with simple logic. Persistent data gives you a mutative API, one that doesn’t update data in-place but always produces new and updated data. The data structures that Immutable.js provides include List, Stack, Map, OrderedMap, Set and more. These structures are highly efficient on modern JavaScript VMs, and minimize the need to cache or copy data.

    This almost class-less CSS library turns your HTML document into a website that looks like a LATEX document. Write semantic HTML, and you are good to go. The source code can be found on GitHub.

Add any optional classes to elements with special styles (author subtitle, abstract, lemmas, theorems, etc.). The labels of theorems, definitions, lemmas and proofs can be changed to other supported languages by including the snippet provided in addition to the main CSS file. Sidenotes can be used as an alternative to footnotes, where the user does not have to jump to the bottom of the page to read it. On mobile, click the superscript to reveal the note. Add a class of left to the span with the sidenote class to make the note appear on the left side of the page on instead of right.

    Numeral.js

    Numeral.js

    A javascript library for formatting and manipulating numbers

    You can use Numerals in the browser and in Node.js. Create an instance of a numeral, Numeral takes numbers or strings that it trys to convert into a number. Numbers can be formatted to look like currency, percentages, times, or even plain old numbers with decimal places, thousands, and abbreviations. And you can always create a custom format. Set a default format so you can use .format() without a string. The default format to '0,0'. Set a custom output when formatting numerals with a value of 0 or null. Adding your own custom formats is as easy as adding a locale. Numeral.js, while less complex, was inspired by and heavily borrowed from Moment.js Formats now exist in their own files and act more or less as plugins. Check out the bytes format for an example of how to create one. When naming locale files use the ISO 639-1 language codes supplemented by ISO 3166-1 country codes when necessary.

    Sizzle

    Sizzle

    A sizzlin' hot selector engine

    A pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. Browser support may differ between standalone Sizzle and libraries that include Sizzle. Please report issues on Sizzle's issue tracker, rather than the trackers for disparate libraries. In order to build Sizzle, you should have Node.js/npm latest and git 1.7 or later (earlier versions might work OK, but are not tested). For Windows you have to download and install git and Node.js. Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Workarounds for Internet Explorer 6 are still in the code but the browser is no longer actively tested. Sizzle supports virtually all CSS 3 Selectors, including escaped selectors (.foo\+bar), Unicode selectors, and more.

    json-forms

    json-forms

    JSON Schema to HTML form generator, supporting dynamic subschemas

    JSON Schema to HTML form generator, supporting dynamic subschemas (on-the-fly resolution). Extensible and customizable library with zero dependencies. Bootstrap add-ons provided. This library supports dynamic schemas, that is, subschemas that can change depending on the value of other parts of the data. This allows the creation of dynamic forms that vary their shape depending on the values entered by the user. This is extremely useful for big autogenerated schemas, that aggregate lots of subschemas and have functional bindings, given that it allows to show the user a simpler, non-error-prone form, also avoiding asking for unneeded data.
