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. -

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. -

7.css
A JS-independent, tree-shakeable CSS framework
7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css. This framework relies on the usage of semantic HTML. To make a button, you'll need to use a button. Input elements require labels. Tabs rely on the role="tab" attribute. This page will guide you through that process, but accessibility is a primary goal of this project. It does not ship with any JavaScript, so it is compatible with your frontend framework of choice.
