V Programming Language
Simple, fast, safe, compiled language for developing software
Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object. -

SuperAgent
Ajax for Node.js and browsers (JS HTTP client)
SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js! Small progressive client-side HTTP request library, and Node.js module with the same API, supporting many high-level HTTP client features. Browser-ready versions of this module are available via jsdelivr, unpkg, and also in the node_modules/superagent/dist folder in downloads of the superagent package. If you are using browserify, webpack, rollup, or another bundler, then you can follow the same usage as Node. SuperAgent is easily extended via plugins. The Node client supports making requests to Unix Domain Sockets. DELETE, HEAD, PATCH, POST, and PUT requests can also be used, simply change the method name. Absolute URLs can be used. In web browsers absolute URLs work only if the server implements CORS. -

Brunch
Web applications made easy
Brunch lets you focus on what matters most, solving real problems instead of messing around with the glue. By being opinionated about your build pipeline, Brunch is able to provide a smooth and fast experience, and makes your config files take a drastic cut. It doesn't take much to get around with brunch. 'brunch new' to create a new project. 'brunch build' to build. 'brunch watch' to live-compile. Installation is one-line, once you have node.js. You will find that the typical config of a Brunch application is an order of magnitude simpler, compared to Webpack, Grunt, or Gulp. Besides configs, brunch is also simpler in terms of commands. Grunt / Gulp commands replicate all plugins it loads. Brunch always has three commands: new, build and watch. Build / watch commands may receive optional production flag which will tell Brunch to optimize assets, javascripts and stylesheets. -

Flux
Application architecture for building user interfaces
Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow. It's more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code. Flux applications have three major parts: the dispatcher, the stores, and the views (React components). These should not be confused with Model-View-Controller. Controllers do exist in a Flux application, but they are controller-views — views often found at the top of the hierarchy that retrieve data from the stores and pass this data down to their children. Additionally, action creators — dispatcher helper methods — are used to support a semantic API that describes all changes that are possible in the application. It can be useful to think of them as a fourth part of the Flux update cycle. -

Essential React
A minimal skeleton for building testable React apps using Babel
A minimal skeleton for building testable React apps using Babel. The design goals are to use fewer tools (no yeoman, gulp, bower, etc...) Babel 6 with Webpack and Hot Loader. Fast testing with mocked-out DOM. Import CSS files as class names. Separate smart and dumb components. No specific implementation of Flux or data fetching patterns. A core philosophy of this skeleton app is to keep the tooling to a minimum. For this reason, you can find all the commands in the scripts section of package.json. This leverages React Hot Loader to automatically start a local dev server and refresh file changes on the fly without reloading the page. It also automatically includes source maps, allowing you to browse code and set breakpoints on the original ES6 code. Build minified app for production using the production shortcut. -

Ramda
A practical functional library for JavaScript programmers
Ramda is a practical functional library for JavaScript programmers. There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. Ramda has a more focused goal. We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data. The primary distinguishing features of Ramda are: Ramda emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code. Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters. The parameters to Ramda functions are arranged to make it convenient for currying. The data to be operated on is generally supplied last.
