    jsblocks

    jsblocks

    Better MV-ish Framework

    From simple user interfaces to complex single-page applications using faster, server-side rendered, and easy-to-learn frameworks. jsblocks is fast but we will not stop here. We have ideas on how to make it even faster. Model-View-Controller, Model-View-Collection, Model-View-ViewModel, Model-View-Whatever, Hierarchical Model-View-Controller or nothing at all - jsblocks has you covered. A Model-View-Collection layer stands on top of the main DOM syncing core. This MVC layer is extremely powerful and enables easy creation of complex applications. The MVC layer is also modular, so you could remove it if you don't need the extra functionality, making your code base lighter. The debugging experience is a major factor that is often overlooked. It brings an easier learning curve and faster development cycles. This is why jsblocks concentrate a lot of effort on building a great debugging experience.

    jsdom

    jsdom

    JavaScript implementation of various web standards, for use with Node

    jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern.

    layui

    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.
