Clarity
Clarity Smart Contracts
Clarity brings smart contracts to Bitcoin. It is a decidable language, meaning you can know, with certainty, from the code itself what the program will do. Clarity is interpreted (not compiled) & the source code is published on the blockchain. Clarity gives developers a safe way to build complex smart contracts for the world's most secure blockchain. The Clarity language uses precise and unambiguous syntax that allows developers to predict exactly how their contracts will be executed. The Clarity language allows users to supply their own conditions for transactions that ensure that a contract may never unexpectedly transfer a token owned by a user. Contracts written in Clarity are broadcasted on the blockchain exactly as they are written by developers. This ensures that the code developers wrote, analyzed, and tested, is exactly what gets executed.Starting Price: Free -

BTC.us
BTC.us
Bitcoin has proven itself as a store of value protocol. Stacks is on a mission to prove that Bitcoin can also be the bedrock of the user owned internet. Stacks brings scalable transactions and expressive smart contracts to Bitcoin, putting Bitcoin’s $1T capital to work. .BTC domains are registered through a smart contract on Stacks, secured by Bitcoin. This smart contract implements a decentralized name registry written in Clarity lang. Ownership of every .BTC name is represented in a hash of the Bitcoin blockchain. Instead of spamming the bitcoin blockchain with name registrations, thousands of Stacks transactions settle in a single transaction on the bitcoin blockchain. The web bridge turns btc.us into the top level domain and allows users to generate subdomains for their personal use. The web bridge is a centralized service, but .BTC names are not. In the future, there can be better support for .btc resolution in browsers.Starting Price: $5 per domain -

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.Starting Price: Free -

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 -
17
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 -

Choreographer-js
Choreographer-js
A simple library to take care of complicated animations. You can also add custom functions that do non-CSS animations! Install and save to your package.json, and include it in your Javascript. Brew up some instant scroll animations. Animate based on scroll location, animate based on mouse X location and create multiple animations based on mouse X location. Now you can create an instance of Choreographer, and run the animations based on whatever measurement floats your boat (ex. scroll position, mouse position, timestamp, whatever). The easiest way to understand how this all works is to check out the examples. Bugs will occur if you overlap animation ranges that affect the same style properties! There are two built-in animation functions available, called 'scale' and 'change'. Progress is what allows for progressive scaling of values (ex. smooth fading of opacity, 2d translation, etc.) If the value is between 0 and 1, that means you are within a range.Starting Price: Free -
