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.

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.

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.

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.
