    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.

    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.

    Moment.js

    Moment.js

    Moment.js

    A JavaScript date library for parsing, validating, manipulating, and formatting dates. Moment was designed to work both in the browser and in Node.js. All code should work in both of these environments, and all unit tests are run in both of these environments. Moment.js has been successfully used in millions of projects. As of September 2020, Moment gets over 12 million downloads per week! Moment has evolved somewhat over the years, but it has essentially the same design as it did when it was created in 2011. Moment works well on Internet Explorer 8 and higher. Some libraries are split into modules, plugins, or companion libraries. Some libraries use the ECMAScript Intl API for locales, time zones, or both. Some libraries still provide their own locale and time zone files as Moment and Moment-Timezone do. Because different locales define week of year numbering differently, Moment.js added options to get/set the localized week of the year.

    Omniscient

    Omniscient

    Omniscient

    Do fast top-down rendering of views while thinking functional programming. Allow your views to be predictable, naturally separated, and composable, but still performant. Omniscient is to React as memoize is to the Fibonacci function. Functional programming for UIs. Memoization for stateless React components. Top-down rendering of components (unidirectional data flow). Favors immutable data (with Immutable.js). Encourages small, composable components, and shared functionality through mixins. Natural separation of concern. Components only deal with their own piece of data. Efficient and centrally defined. In its simplest form, an Omniscient component is a Stateless React Component, but more optimized. Omniscient is just as much a way to think when you are building applications as a library itself. As Omniscient is wrapped in a UMD you can use it many different ways, through CommonJS, AMD, or just through the window object.

    Popper

    Popper

    Popper

    Positioning tooltips and popovers are difficult. Popper is here to help! Given an element, such as a button, and a tooltip element describing it, Popper will automatically put the tooltip in the right place near the button. It will position any UI element that "pops out" from the flow of your document and floats near a target element. The most common example is a tooltip, but it also includes popovers, drop-downs, and more. All of these can be generically described as a "popper" element. Click on the dots to place the tooltip. There are 12 different placements to choose from. Pure CSS poppers will not be prevented from overflowing clipping boundaries, such as the viewport. It will get partially cut off or overflows if it's near the edge since there is no dynamic positioning logic. When using Popper, your popper will always be positioned in the right place without needing manual adjustments.

    Three.js

    Three.js

    Three.js

    Three.js is a JavaScript 3D library. The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available in the examples. To actually be able to display anything with three.js, we need three things, scene, camera, and renderer, so that we can render the scene with the camera. In addition to the WebGLRenderer, Three.js comes with a few others, often used as fallbacks for users with older browsers or for those who don't have WebGL support for some reason. Create a loop that causes the renderer to draw the scene every time the screen is refreshed (on a typical screen this means 60 times per second). Anything you want to move or change while the app is running has to go through the animate loop. You can of course call other functions from there.

    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.

    Velocity.js

    Velocity.js

    Velocity.js

    Velocity is an animation engine with the same API as jQuery's animate. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined. 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.

    Modernizr

    Modernizr

    Modernizr

    Modernizr tells you what HTML, CSS, and JavaScript feature the user’s browser has to offer. It’s a collection of superfast tests, or “detects” as we like to call them, which run as your web page loads, then you can use the results to tailor the experience to the user. All web developers come up against differences between browsers and devices. That’s largely due to different feature sets, the latest versions of the popular browsers can do some awesome things which older browsers can’t, but we still have to support the older ones. Modernizr makes it easy to deliver tiered experiences and make use of the latest and greatest features in browsers that support them, without leaving less fortunate users high and dry. Modernizr is a small piece of JavaScript code that automatically detects the availability of next-generation web technologies in your user's browsers. Modernizr uses feature detection to allow you to easily tailor your user's experience.

    RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code. This setup assumes you keep all your JavaScript files in a "scripts" directory in your project. To take full advantage of the optimization tool, it is suggested that you keep all inline script out of the HTML, and only reference require.js with a requirejs call like so to load your script. All of them map to loading some/path/some/module.js. Ideally we could choose the CommonJS syntax, since it is likely to get more common over time, and we want to reuse code.

    Backbone.js

    Backbone.js

    Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. 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.
