    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.

    Inferno

    Inferno

    React-like JavaScript library for building modern user interfaces

    Inferno is an insanely fast, React-like library for building high-performance user interfaces on both the client and server. React-like API, concepts and component lifecycle events. Switch over easily with inferno-compat. One of the fastest front-end frameworks for rendering UI in the DOM, making 60 FPS on mobile possible. Isomorphic rendering on both client and server, along with fast-booting from server-side renders. Inferno doesn't have a fully synthetic event system like React does. Inferno has a partially synthetic event system, instead opting to only delegate certain events (such as `onClick`). Inferno doesn't support React Native. Inferno was only designed for the browser/server with the DOM in mind. Inferno doesn't support legacy string refs, use `createRef` or callback `ref` API. Inferno provides lifecycle events on functional components. This is a major win for people who prefer lightweight components rather than ES2015 classes.

    Webpack Encore

    Webpack Encore

    A simple but powerful API for processing and compiling assets

    Symfony ships with a pure-JavaScript library, called Webpack Encore, that makes it a joy to work with CSS and JavaScript. You can use it, use something else, or create static CSS and JS files in your public/ directory directly and include them in your templates. Webpack Encore is a simpler way to integrate Webpack into your application. It wraps Webpack, giving you a clean & powerful API for bundling JavaScript modules, pre-processing CSS & JS, and compiling and minifying assets. Encore gives you a professional asset system that's a delight to use. Encore is inspired by Webpacker and Mix, but stays in the spirit of Webpack, using its features, concepts and naming conventions for a familiar feel. It aims to solve the most common Webpack use cases. Encore is made by Symfony and works beautifully in Symfony applications. But it can easily be used in any application in any language!

    express-session

    express-session

    Simple session middleware for Express

    This is a Node.js module available through the npm registry. Installation is done using the npm install command provided in the instructions. Create a session middleware with the given options. Session data is not saved in the cookie itself, just the session ID. Session data is stored server-side. Since version 1.5.0, the cookie-parser middleware no longer needs to be used for this module to work. This module now directly reads and writes cookies on req/res. Using cookie-parser may result in issues if the secret is not the same between this module and cookie-parser. The default server-side session storage, MemoryStore, is purposely not designed for a production environment. It will leak memory under most conditions, does not scale past a single process, and is meant for debugging and developing.

    nivo

    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.

    pika-pack

    pika-pack

    Build your npm package using composable plugins

    pika-pack is an archived npm package build tool created to simplify how JavaScript libraries are prepared for publishing. It lets package authors define a build pipeline with small, composable plugins instead of hand-configuring every build step. The tool can wrap common build systems such as Babel and Rollup with npm-friendly defaults. It can generate optimized package outputs for different targets, including Node, web, and type definition workflows. pika-pack also helps produce package metadata, which reduces the amount of manual package setup required. Because the repository is archived, it is most useful today as a historical reference for package build automation and plugin-based publishing workflows.

    Screwdriver API

    Screwdriver API

    An open source build platform designed for continuous delivery

    Screwdriver is an open-source build platform designed for Continuous Delivery. Screwdriver began as a hack for simplified interfacing with Jenkins at Yahoo in 2012. As the volume of builds increased, it became clear that Jenkins was not stable or feasible to use at the scale we were running builds. In 2016, we rebuilt Screwdriver from scratch in open source with our best coding practices and CICD goals in mind. Screwdriver is executor and SCM-agnostic, meaning you can choose whichever plugin better suits your need or build your own. It's completely free and open-source, and our team is actively maintaining the code. Screwdriver is a self-contained, pluggable service to help you build, test, and continuously deliver software using the latest containerization technologies. We support an expanding list of source code services, execution engines, and databases so Screwdriver can work in your ecosystem.

    Shoutem UI

    Shoutem UI

    Customizable set of components for React Native applications

    Shoutem UI is a set of styleable components that enables you to build beautiful React Native applications for iOS and Android. All of our components are built to be both composable and customizable. Each component has a predefined style that is compatible with the rest of the Shoutem UI, which makes it possible to build complex components that look great without the need to manually define complex styles. You can also use standard React Native components in your layouts anywhere you want, but they will not inherit either the theme or the parent styles, so you will need to style them manually. Shoutem UI is a part of the Shoutem UI Toolkit that enables you to build professional-looking React Native apps with ease.

    UI Bootstrap

    UI Bootstrap

    Bootstrap components written in pure AngularJS by the AngularUI Team

    Bootstrap components written in pure AngularJS by the AngularUI Team. UI Bootstrap provides a set of native AngularJS directives based on Bootstrap's markup and CSS. As a result no dependency on jQuery or Bootstrap's JavaScript is required. Build files for all directives are distributed in several flavours: minified for production usage, un-minified for development, with or without templates. It should be noted that the -tpls files contain the templates bundled in JavaScript, while the regular version does not contain the bundled templates. Alternativelly, if you are only interested in a subset of directives, you can create your own build. Whichever method you choose the good news that the overall size of a download is fairly small: 122K minified for all directives with templates and 98K without (~31kB with gzip compression, with templates, and 28K gzipped without).

    UpUp

    UpUp

    Easily create sites that work offline as well as online

    UpUp is a tiny JavaScript library that makes sure your users can always access your site's content, even when they're on a plane, in an elevator, or 20,000 leagues under the sea. Your users are no longer sitting at their desktops, with a wire connecting them to the internet. They are visiting your site from a phone in an elevator, from their tablet on the subway, or on their laptop while they sit cramped into seat 25 E. This is why modern browsers support service workers, a new technology which lets you serve your content to your users, even when they are offline. UpUp is a free, open-source project which makes using this modern magic as simple as calling one command. While easy to pick up, UpUp is powerful enough to support anything from showing simple messages, to making fully functional single-page applications available offline, with data customized for each of your users.

    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.

    clsx

    clsx

    A tiny utility for constructing `className` strings conditionally

    clsx is a tiny JavaScript utility (roughly a few hundred bytes) for constructing className strings conditionally, commonly used in React and other component frameworks. It is intended as a faster and smaller drop-in replacement for the popular classnames package, but with a minimalistic API and implementation. The function accepts any number of arguments in a variety of forms: strings, numbers, arrays, and objects where truthy values indicate which classes to include. It then returns a deduplicated, space-separated class string that can be applied directly to HTML or JSX className attributes. The library is distributed in multiple formats (ESM, CommonJS, and UMD) so it works well in bundlers, Node environments, and direct tags. Because it has zero dependencies and a stable API, it is widely used in both small projects and large production codebases where bundle size is a concern.

    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.
