Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click. JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud.

    Brunch

    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.

    V Programming Language

    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.

    Workbox

    Workbox

    JavaScript libraries for Progressive Web Apps

    Workbox is a set of libraries that can power a production-ready service worker for your Progressive Web App. Stop waiting on the network! You can improve your web app's performance by caching and serving your files, powered by a service worker. Even on an unreliable connection, your web app can still work using the right runtime caching strategies. Looking to build a progressive web app? Workbox makes it easy to create an offline first experience. Workbox is a library that bakes in a set of best practices and removes the boilerplate every developer writes when working with service workers. Precaching, runtime caching, strategies, request routing, background sync, and helpful debugging. Wish you could rely on Google Fonts being available offline after the user has visited your site? Add a quick rule to serve them from the cache. Make your JS and CSS fast by returning the assets from the cache, while making sure they are updated in the background for the next use.

    Flux

    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.

    Relay

    Relay

    JavaScript framework for building data-driven React applications

    Relay is data-fetching turned declarative. Components declare their data dependencies, without worrying about how to fetch them. Relay guarantees that the data each component needs is fetched and available. This keeps components decoupled and promotes reuse. With Relay, components and their data dependencies can be quickly modified without modifying other parts of the system. That means you won't accidentally break other components as you refactor or make changes to your app. Relay's compiler aggregates and optimizes the data requirements for your entire app, so that they can be efficiently fetched in a single GraphQL request. Relay handles the heavy lifting to ensure the data declared by your components is fetched in the most efficient way. For example, by deduplicating identical fields, and precomputing information used at runtime, among other optimizations. Relay also supports executing GraphQL Mutations, optionally with optimistic updates, and updates to local data.

    mui

    mui

    High-performance framework closest to native APP experience

    The gap between performance and experience has always been the primary reason for mobile app developers to abandon HTML5. The browser’s natural page-cutting white screen, the unbearable turning animation, the jittering of floating elements, and the inability to pull down to refresh smoothly, all of which frustrate HTML5 developers, especially when they get a low-end Android machine to run, and the phone falls. On the other hand, the browser default control styles are few and ugly, making a beautiful control is very troublesome, and there are some simple UI frameworks but low performance. The mui framework effectively solves these problems. This is a framework that can facilitate the development of high-performance apps, and it is also the framework that is closest to the effect of native apps.

    nivo

    A rich set of dataviz components

    nivo provides a rich set of dataviz components, built on top of the awesome d3 and Reactjs libraries. Several libraries already exist for React d3 integration, but just a few provide server side rendering ability and fully declarative charts. In order to use nivo, you have to install the @nivo/core package and then choose some of the scoped @nivo packages according to the charts you wish to use. Given an array of data series having an id and a nested array of points (with x, y properties), it will compute the line for each data series. All datum having null x or y will be treated as holes, thus portions of the corresponding line will be skipped. You can fully customize it using the circleComponent property to define your own, if you wish to do so you should have a look at the default SVG component to get started. Bar chart which can display multiple data series, stacked or side by side. Also supports both vertical and horizontal layout, with negative values descending below the x axis.
