Annual subscriptions include free updates over the next 12 months. One-time payments include unlimited updates up to the major version.

Preact is the Virtual DOM abstraction that is the thinnest. It is built on stable platform features and registers real event handlers. It also works well with other libraries. Most UI frameworks can be large enough to make up the majority of an app’s JavaScript size. Preact is different. It's small enough to make your code the largest part your application. This means that JavaScript takes less time to download, parse, and execute. You can create the experience you want without worrying about keeping a framework in place. Preact is small and fast. Preact is one of the fastest Virtual DOM Libraries due to its simple and predictable diff implementation. Preact is optimized for performance by batching updates. Preact's performance is maximized when we work closely with web engineers.

Leaflet is the most popular open-source JavaScript library to create mobile-friendly interactive maps. It is only 42KB in size and has all the mapping features that most developers need. Leaflet was designed to be simple, fast, and easy to use. It is compatible with all major mobile and desktop platforms. It can be extended with many plugins. It has a beautiful, well-documented API that is easy to use and readable source code that makes it easy to contribute. Leaflet isn't trying to be everything to everyone. Leaflet focuses on the essentials and makes them work perfectly. Mobile apps feel as smooth as native apps thanks to hardware acceleration. CSS3 features are used to make zooming and panning very easy. It's very fast thanks to smart polyline/polygon rendering that includes dynamic clipping and simplifying. Modular build system allows you to leave out features that you don't use. Mobile tap delay elimination

An experiment in CSS background sharing across multiple elements. Multiple.js can be used to achieve a "background sharing across multiple element" effect in HTML/CSS with no JavaScript coordinates processing. You will notice that icons and text in lighter layers have a gradient-color with darker layers. This creates the illusion of an underlay violet layer. Layers can also pass the background image (girl), with equal transparency, so layers cannot be superimposed on one another. These things can all be done in CSS. To ensure that the background remains in the same place, you can add a gap between elements. You can see how it looks by switching between background image/gradient. To ensure that elements are independent, you can remove random layers. Displays the appropriate amount of background in each element. Background can be successfully extended to full size viewport.

A JavaScript date library that can be used to parse, validate, manipulate, and format dates. Moment can be used in both Node.js and the browser. All code should be compatible with both browsers and Node.js. Unit tests can also be run in both environments. Moment.js has been used in millions of projects. Moment.js has been downloaded more than 12 million times per week as of September 2020. Moment has changed over time, but it still has the same design as when it was first created in 2011. Moment is compatible with Internet Explorer 8 or higher. Some libraries can be divided into modules, plugins, and companion libraries. Some libraries use the ECMAScript Intl API to determine time zones or locales. Some libraries still offer their own time zone and locale files, just like Moment and Moment-Timezone. Moment.js now offers options to set/get the localized week of a year because different locations have different definitions.

Masonry is a JavaScript grid library. It works by placing elements in the optimal positions based on available vertical spaces, much like a mason fitting stone in a wall. It is likely that you have seen it in action all over the Internet. Your own CSS handles all styling and sizing of items. For responsive layouts, item sizes can be adjusted with percentages. Unloaded images can cause Masonry layouts to be distorted and item elements to overlap. imagesLoaded solves this problem. ImagesLoaded is a separate script that you can download. You can initialize Masonry using HTML without having to write any JavaScript. All options are possible, but it is recommended that you select the item and column width. Align items to a horizontal grid. For responsive layouts with percentage widths, you can use element sizing. You can control the Masonry layout's size within your CSS using element sizing options. This is useful for media queries and responsive layouts.

While thinking functional programming, do fast top-down renderings of views. Your views should be predictable, easily separated, composable, and still performant. Omniscient is to react as memoize to the Fibonacci function. Functional programming for UIs. Memoization of stateless React components. Top-down rendering components (unidirectional data flow). Favors immutable data (with the Immutable.js). Encourages small, modular components and shared functionality via mixins. Natural separation of concerns. Each component only deals with its own data. It is efficient and centrally controlled. An Omniscient component, in its simplest form is a Stateless react component, but it is more optimized. Omniscient is as much a way of thinking when you're building applications as it is a library. Omniscient is wrapped in UMD so you can use it in many different ways. CommonJS, AMD or just through the window object.

Parsley, the ultimate JavaScript validation library. Validating frontend forms has never felt so easy. Parsley is a form validation library like no other. Simply write your requirements in English inside your HTML tags and Parsley will take care of the rest. Simple form validation is as easy as typing a single JavaScript line. Parsley is smarter. It automatically detects any modifications to your forms and adjusts its validation accordingly. Parsley validation is as easy as adding, removing, or editing fields. Parsley comes with more than a dozen validators. Parsley comes with a dozen validators. You can also use the Parsley extra Ajax validator, or any number of extended validators that the community has made available. Parsley is very focused on UX and UI. You can override almost all default Parsley behavior to suit your needs. Still ships almost bug-free. Parsley has been rigorously tested and aims for compatibility with every browser (including IE8).

It is difficult to position popovers and tooltips. Popper is here to help. Popper will automatically place the tooltip near the button if you provide an element such as a button. Popper will position any UI element that "pops up" from your document and floats close to a target element. A tooltip is the most common, but you can also use drop-downs and popovers. These can all be described as "popper" elements. To place the tooltip, click on the dots. There are 12 possible placements. Pure CSS poppers won't be able to overflow clipping boundaries such as the viewport. It will be cut off partially or overflow if it is near the edge, since there is no dynamic position logic. Popper ensures that your popper is always in the correct place.

Three.js is a JavaScript 3D Library. The project's goal is to create a lightweight, cross-browser, general purpose 3D library that is easy to use. While the current builds only have a WebGL renderer, there are examples that include WebGPU (experimental), SVG, and CSS3D renderers. Three.js can display any scene. It also needs a camera, renderer, and scene. Three.js includes a few other tools, which are often used as fallbacks for older browsers and those who don't have WebGL support. A loop can be created that causes the renderer's scene to be drawn every time the screen refreshes (on a typical screen, this is 60 times per second). The animate loop is required to change or move any object in the app. You can also call other functions from the animate loop.

This wrapper allows cross-browser JavaScript Fullscreen API usage. It lets you bring any element or page into fullscreen. This wrapper smoothens out differences in browser implementations so you don’t have to. Version 5.2.0 is recommended if you are unable to use ESM, or if you need to support older browsers with transpilation. Only 0.7 kB zip. Also available on cdnjs, older version. Safari is supported on desktops as well as iPads, but not iPhones. This is a browser limitation, not Screenfull. Fullscreen the page, or an element. Hide the navigation user interface for mobile devices Fullscreen an element using jQuery and toggle fullscreen for an image using jQuery Angular.js can detect fullscreen change, remove listeners and detect fullscreen errors. Remember that the browser will only enter fullscreen if it is initiated by user events such as click, touch, key, or key.

The Polymer library offers a variety of features that allow you to create custom elements. These features make it easy and faster to create custom elements that function like standard DOM elements. Polymer elements can be created using a constructor, document creation element, and configured using attributes and properties. Each instance is responsive to changes in property and attribute, styled with externally or internal defaults, and responsive to methods to modify its internal state. Registering an element creates a class that associates it with a custom name. To manage an element's lifecycle, the element provides callbacks. Polymer allows you to declare properties. This allows you to integrate your element’s property API with the Polymer database system. Shadow DOM creates a local, encapsulated tree of DOM for your element. A DOM template can be used to automatically create and populate a Shadow Tree for Polymer.

Velocity is an animation engine that uses the same API as jQuery animate. It can be used with or without jQuery. It is extremely fast and supports color animation, loops and easings as well as SVG support and scrolling. It combines the best of jQuery with CSS transitions. Velocity can be downloaded and placed on your page. It will replace all instances jQuery's animated with velocity. You will notice a significant performance improvement across all browsers and devices, particularly on mobile. Velocity works on all browsers, including IE8 and Android 2.3. It mimics jQuery’s queue and interoperates seamlessly and seamlessly with jQuery’s animate, fade and delay. Your code doesn't have to change because Velocity's syntax matches animate. JavaScript and jQuery can be mistakenly conflated. Velocity uses JavaScript animation. jQuery animation is slower. Velocity is a companion to jQuery but it uses its own animation stack which delivers its performance.

Modernizr shows you the HTML, CSS, or JavaScript features that your browser offers. It's a collection superfast tests or "detects", which run as soon as your web page loads. The results can then be used to tailor the user's experience. Every web developer faces differences between browsers and devices. This is due to differences in feature sets. While the most recent browsers can do amazing things that older browsers cannot, we still need to support older browsers. Modernizr allows you to create tiered experiences and take advantage of the latest features in browsers that support them. It doesn't leave less fortunate users out in the cold. Modernizr is a JavaScript script that detects next-generation web technologies in the browsers of your users. Modernizr makes it easy to tailor the user's experience by using feature detection.

Users can solve a maze with Blockly's editor to the right. Blockly plugins are small, self-contained code pieces that add functionality to Blockly. Plugins allow you to add fields, define themes, create renderers and many other functions. Blockly codelabs offer step-by-step instructions for how to customize and use Blockly. Blockly offers a variety of examples that demonstrate how to use its features.

RequireJS is a JavaScript module loader and file. It is optimized for use in-browser, but can also be used in other JavaScript environments like Rhino or Node. RequireJS is a modular script loader that will increase the speed and quality your code. This configuration assumes that you keep all JavaScript files in a "scripts” directory in your project. To maximize the optimization tool's capabilities, it is recommended that you keep all your inline script out the HTML and that you only use require.js to load your script. All of them map to loading some/path/some/module.js. We would prefer to use the CommonJS syntax as it is more common and allows us to reuse code.
