jQuery
jQuery JavaScript library
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery also supports Node, browser extensions, and other non-browser environments. To build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported. Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules. -

Node.js
Cross-platform JavaScript runtime environment
Node.js is a free, open-source, cross-platform JavaScript runtime environment that allows developers to run JavaScript outside of the browser. It is built on Chrome’s V8 engine and is designed for building fast, scalable network applications. Node.js enables developers to create servers, APIs, command-line tools, and full-stack web applications using a single programming language. Its non-blocking, event-driven architecture makes it highly efficient for handling concurrent requests. The ecosystem is supported by npm, one of the largest package managers, providing access to thousands of libraries and tools. Node.js is widely used for backend development, real-time applications, and microservices architectures. -

SQLite compiled to JavaScript
A javascript library to run SQLite on the web
sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database. -

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. -

A function can also be passed to control this behavior dynamically based on the path to the asset. Starting with version 4.0.0, absolute paths are parsed based on the server root. Using local value requires you to specify :global classes. Using global value requires you to specify :local classes. Using pure value requires selectors must contain at least one local class or id. Styles can be locally scoped to avoid globally scoping styles. The syntax :local(.className) can be used to declare className in the local scope. The local identifiers are exported by the module. -

Angular Schema Form
Generate forms from a JSON schema, with AngularJS
Schema Form was built to be extended and its easy to create your own form field types that suit your specific requirement. Much of the new development is being done in Assimilate, a standardized validator for JSON Schema to help ensure changing validators is never as painful as escaping tv4 is, as well as a new core library to allow for a more predictable upgrade from AngularJS to Angular. Schema Form is a set of AngularJS directives (and a couple of services). It can do two things to make life easier. Create a form directly from a JSON schema. Validate form fields against that same JSON schema. Schema Form uses convention over configuration, so it comes packaged with some sensible defaults. But you can always customize it by changing the order and types of form fields. Schema Form is inspired by the nice JSON Form library and aims to be roughly compatible with it, especially its form definition.
