asar
Simple extensive tar-like archive format with indexing
Asar is a simple extensive archive format, it works like tar that concatenates all files together without compression while having random access support. You can pass in a transform option, which is a function, that either returns nothing or a stream. Transform. The latter will be used on files that will be in the .asar file to transform them. There is also an unofficial grunt plugin to generate asar archives at bwin/grunt-asar. Asar uses Pickle to safely serialize binary value to file, there is also a node.js binding of Pickle class. The header_size and header are serialized with Pickle class, and header_size's Pickle object is 8 bytes. offset and size record the information to read the file from the archive, the offset starts from 0 so you have to manually add the size of header_size and header to the offset to get the real offset of the file. -

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. -

Less.js
Less, the dynamic stylesheet language
Less (which stands for Leaner Style Sheets) is a backwards-compatible language extension for CSS. This is the official documentation for Less, the language and Less.js, the JavaScript tool that converts your Less styles to CSS styles. Because Less looks just like CSS, learning it is a breeze. Less only makes a few convenient additions to the CSS language, which is one of the reasons it can be learned so quickly. Less gives you the ability to use nesting instead of, or in combination with cascading. Arithmetical operations can operate on any number, color or variable. If it is possible, mathematical operations take units into account and convert numbers before adding, subtracting or comparing them. The result has leftmost explicitly stated unit type. If the conversion is impossible or not meaningful, units are ignored. With Less you can transform colors, manipulate strings and do maths. -

html-loader
HTML Loader
Exports HTML as a string. HTML is minimized when the compiler demands. The true value enables the processing of all default elements and attributes, the false value disables the processing of all attributes. Allows you to specify which tags and attributes to process, filter them, filter urls and process sources starting with /. Allows to setup which tags and attributes to process and how, as well as the ability to filter some of them. Filter can also be used to extend the supported elements and attributes. By default, the parser in html-loader interprets content inside noscript tags as #text, so processing of content inside this tag will be ignored. A very common scenario is exporting the HTML into their own .html file, to serve them directly instead of injecting with javascript. -

layui
Classic modular front-end UI framework
Created by professional front-end, for full-level front-end and back-end developers, a low-threshold, out-of-the-box front-end UI solution. Layui (homonym: UI-like) is a front-end UI framework written with its own module specifications, following the writing and organization of native HTML/CSS/JS, with a very low threshold and ready to use. Its exterior is minimalist, but it does not lose its fullness. The volume is light and the components are abundant. Every detail from the core code to the API has been carefully crafted, which is very suitable for the rapid development of the interface. The first version of layui was released in the golden autumn of 2016. It is different from those UI frameworks based on the underlying MVVM.
