    Polymer

    Polymer

    Polymer

    The Polymer library provides a set of features for creating custom elements. These features are designed to make it easier and faster to make custom elements that work like standard DOM elements. Similar to standard DOM elements, Polymer elements can be instantiated using a constructor or document creation element, configured using attributes or properties, populated with internal DOM inside each instance, responsive to property and attribute changes, styled with internal defaults or externally, and responsive to methods that manipulate its internal state. Registering an element associates a class with a custom element name. The element provides callbacks to manage its lifecycle. Polymer also lets you declare properties, to integrate your element's property API with the Polymer data system. Shadow DOM provides a local, encapsulated DOM tree for your element. Polymer can automatically create and populate a shadow tree for your element from a DOM template.

    Million.js

    Million.js

    Million.js

    Million.js introduces a novel "block" virtual DOM. It's significantly faster than React's virtual DOM, as it diffs data instead of the DOM. Million.js uses a custom compiler that automatically optimizes your React components on the server. Tired of learning new frameworks and big migrations? Million.js ships a drop-in automatic mode to make your React apps faster, without any code changes. We use a novel approach to the virtual DOM called the block virtual DOM. You can read more on what the block virtual DOM is with virtual DOM, back in block and how we make it happen in React with behind the block(). We are actively working on removing these limitations. It's also important to note that your application may not need Million.js – if your app is not UI heavy, you may not see much performance improvement.

    Preact

    Preact

    Preact

    Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.

    Multiple.js

    Multiple.js

    An experiment in sharing background across multiple elements using CSS. If you want to accomplish a "background sharing across multiple elements" effect in HTML/CSS without any coordinates processing by JavaScript, Multiple.js is the answer. Note that icons and text at lighter layers have gradient-color from darker layers, creating the illusion of an underlying violet layer. In addition to that, layers pass the background image (girl) with equal transparency so that layers can not be superimposed on each other. All these things can be implemented in CSS. Add a gap between elements to make sure that the background remains in the same position. Toggle background image/gradient to get idea how it looks. Miss random layers to make sure that elements are independent. Expands background to viewport's size and displays in every element appropriate chunk, exactly what is needed! Background can be successfully expanded to full viewport size.

    Format your <input/> content when you are typing. Cleave.js has a simple purpose, to help you format input text content automatically. Credit card number formatting, phone number formatting (i18n js lib separated for each country to reduce size), date formatting, numeral formatting, custom delimiter, prefix and block pattern, CommonJS/AMD mode, ReactJS component, AngularJS directive (1.x), and ES module. The idea is to provide an easy way to increase input field readability by formatting your typed data. By using this library, you won't need to write any mind-blowing regular expressions or mask patterns to format input text. However, this isn't meant to replace any validation or mask library, you should still sanitize and validate your data in the backend. Types are contributed by the community. Types for the React component are also available and can be imported in the same way.

    React

    React

    React

    React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable and easier to debug. Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM. We don’t make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props.

    Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR - a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM.

Download Velocity, include it on your page and replace all instances of jQuery's animate with velocity. You will immediately see a performance boost across all browsers and devices, especially on mobile. Velocity works everywhere, back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.

Initialize AOS, recalculate all offsets and positions of elements (called on window resize), reinitiate the array with AOS elements, and trigger refresh (called on DOM changes that are related to AOS elements). By default, AOS is watching for DOM changes and if there are any new elements loaded asynchronously or when something is removed from DOM it calls refreshHard automatically. In browsers that don't support MutationObserver like IE, you might need to call it by yourself. You can also tell AOS to trigger a custom event on a specific element.

When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.

    FormValidation

    FormValidation

    FormValidation

    From v1.0.0, the library is rewritten in Typescript and ES6 completely. The giant and old jQuery plugin doesn't exist anymore. With the new plugin-based architecture, the library has really small core. Everything else is built around as a plugin. Each file in the dist/css and dist/js folders has two versions: the normal code in the .css, .js files, and the minified code in the .min.css, .min.js files. In order to reduce the page loading time and enhance the user experience when visiting your site, you should use the .min.css, .min.js files in the production website. Meanwhile, in the development mode, you should use the normal files without .min part to debug the code more easy.

    pygame

    pygame

    pygame

    Pygame is a set of Python modules designed for writing video games. Pygame adds functionality on top of the excellent SDL library. This allows you to create fully featured games and multimedia programs in the python language. Pygame is highly portable and runs on nearly every platform and operating system. Pygame is free. Released under the LGPL license, you can create open-source, freeware, shareware, and commercial games with it. With dual-core CPUs common, and 8-core CPUs cheaply available on desktop systems, making use of multi-core CPUs allows you to do more in your game. Selected pygame functions release the dreaded python GIL, which is something you can do from C code. Uses optimized C and assembly code for core functions. C code is often 10-20 times faster than python code, and assembly code can easily be 100x or more times faster than python code. Comes with many operating systems. Just an apt-get, emerge, pkg_add, or just install away.

    Nullstack

    Nullstack

    Nullstack

    Write the backend and frontend of a feature in a single component and let the framework decide where the code should run. Nullstack provides you with all the tools you need to stay focused on the product. On the first render, you'll get SEO-ready HTML optimized for the first paint of your route in a single request using local functions with zero JavaScript dependencies in the client bundle. After the content is served and the network is idle Nullstack JavaScript is loaded, the state of the application is restored through hydration and it becomes a single-page application. Subsequent server functions will fetch JSON from an automatically generated microservice API, deserialize the response, update the application state, and rerender the page out of the box. A full stack lifecycle combined with a feature-driven mindset allows you to write clean and reusable code without the need to create APIs manually.

    yarl

    yarl

    Python Software Foundation

    All URL parts, scheme, user, password, host, port, path, query, and fragment are accessible by properties. All URL manipulations produce a new URL object. Strings passed to constructor and modification methods are automatically encoded giving canonical representation as result. Regular properties are percent-decoded, use raw_ versions for getting encoded strings. Human-readable representation of URL is available as .human_repr(). PyPI contains binary wheels for Linux, Windows and MacOS. If you want to install yarl on another operating system (like Alpine Linux, which is not manylinux-compliant because of the missing glibc and therefore, cannot be used with our wheels) the tarball will be used to compile the library from the source code. It requires a C compiler and Python headers installed. Please note that the pure-Python (uncompiled) version is much slower. However, PyPy always uses a pure-Python implementation, and, as such, it is unaffected by this variable.
