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.Starting Price: Free -

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.Starting Price: Free -

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.Starting Price: Free -

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. -

Undo
Undo
Empowering developers to understand their codebase and fix bugs faster with time travel debugging. UDB is the leading time travel debugger for Linux C/C++ applications. Resolve complex software defects in development or in production up to 10x faster. Debugging software failures takes time. It slows down development and disrupts customers. What if you could record your program's execution as it fails and replay the recording offline (any time, anywhere) to see exactly what happened? LiveRecorder is the leading enterprise-grade Software Failure Replay platform. Time Travel Debugging greatly improves team productivity in development. It is also ideal to debug test failures. Travel forward and backward in time to inspect the program state. Undo enables developers to see through that complexity and create better software faster. With Undo’s time travel debugging, developers no longer need to waste time figuring out what the code is doing. -

Cleave.js
Cleave.js
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.Starting Price: Free -

D3.Js
Mike Bostock
D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS. -

Semantic UI React
Vercel
Semantic UI React is the official React integration for Semantic UI. jQuery-free, declarative API, augmentation, shorthand props, sub-components, auto controlled state. jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components.Starting Price: Free -
