react-window
React components for rendering large lists and tabular data
React window works by only rendering part of a large data set (just enough to fill the viewport). This helps address some common performance bottlenecks. It reduces the amount of work (and time) required to render the initial view and to process updates. It reduces the memory footprint by avoiding over-allocation of DOM nodes. react-window is a complete rewrite of react-virtualized. If react-window provides the functionality your project needs, it is strongly recommend that you use it instead of react-virtualized. However if you need features that only react-virtualized provides, you have two options. Use react-virtualized. (It's still widely used by a lot of successful projects!). Or, create a component that decorates one of the react-window primitives and adds the functionality you need. You may even want to release this component to NPM (as its own, standalone package)! -

Chokidar
Minimal and efficient cross-platform file watching library
Chokidar is a solution for all the users of Node.js fs.watch who are tired of it not reporting filenames on MacOS and events at all when using editors like Sublime on MacOS. Node.js fs.watch often reports events twice, emits most changes as rename, and it does not provide an easy way to recursively watch file trees nor supports recursive watching on Linux. Same as with Node.js fs.watchFile. Therefore, Chokidar resolves these problems. Initially made for Brunch (an ultra-swift web app build tool), it is now used in Microsoft's Visual Studio Code, gulp, karma, PM2, browserify, webpack, BrowserSync, and many others. It has proven itself in production environments. Chokidar does still rely on the Node.js core fs module, but when using fs.watch and fs.watchFile for watching, it normalizes the events it receives, often checking for truth by getting file stats and/or dir contents. -

Flow Typed
A central repository for Flow library definitions
High-quality library definitions for Flow. flow-typed is a repository of third-party library interface definitions for use with Flow. When you start a project with Flow, you likely want to use some third-party libraries that were not written with Flow. By default, Flow will just ignore these libraries leaving them untyped. As a result, Flow can't give errors if you accidentally misuse the library (nor will it be able to auto-complete the library). To address this, Flow supports library definitions which allow you to describe the interface of a module or library separate from the implementation of that module/library. The flow-typed repo is a collection of high-quality library definitions, tests to ensure that definitions remain high quality, and tools to make it as easy as possible to import them into your project. All you have to do when you add one or more new dependencies to your project is run flow-typed install. -

React-WeUI
WeUI Components build with React
React-WeUI is a React component library that brings WeUI, the interface system associated with WeChat-style mobile design, into the React development workflow. Its purpose is to let developers build mobile-oriented interfaces with React while preserving the visual language and component behavior expected from WeUI. The project combines React components with the underlying WeUI styling, which means teams can work in a modern component architecture instead of manually stitching together markup and CSS for each screen. The repository includes documentation with live examples, installation options for both package managers and browser-based usage, and example code that shows how quickly a page can be assembled from imported components. Because of its heritage, React-WeUI is especially relevant for mobile web experiences, lightweight app-like pages, and products targeting users familiar with WeChat-inspired interaction patterns. -

Riot
Simple and elegant component-based UI library
Why do we need a new UI library? The frontend space is indeed crowded, but we honestly feel the solution is still “out there”. We believe Riot.js offers the right balance for solving the great puzzle. Riot.js brings custom elements to all modern browsers without the use of any polyfill! A custom element glues relevant HTML and JavaScript together forming a reusable component. It is designed to offer you everything you wished native the web components API looked like. HTML syntax is the de facto language of the web and it’s designed for building user interfaces. The syntax is explicit, nesting is inherent to the language, and attributes offer a clean way to provide options for custom tags. Minimalism sets Riot.js apart from others. One of the design goals was to introduce a powerful tag syntax with as little boilerplate as possible. Riot.js has between 10 and 100 times fewer API methods than other UI libraries. -

SQLite compiled to JavaScript
A javascript library to run SQLite on the web
sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database. -

date-fns
Modern JavaScript date utility library
date-fns is a modern JavaScript date utility library that offers the most comprehensive toolset for manipulating JavaScript dates in a browser and Node.js. It’s complete and yet simple, because the API is unambiguous, with just one approach to a problem. It’s highly reliable and consistent, always respecting timezones and DST. And it’s also modular, so you don’t have to bloat your project with unnecessary functionality. date-fns supports TypeScript and Flow, and is supported by an amazing community with dozens of locales. -
22
json-forms
JSON Schema to HTML form generator, supporting dynamic subschemas
JSON Schema to HTML form generator, supporting dynamic subschemas (on-the-fly resolution). Extensible and customizable library with zero dependencies. Bootstrap add-ons provided. This library supports dynamic schemas, that is, subschemas that can change depending on the value of other parts of the data. This allows the creation of dynamic forms that vary their shape depending on the values entered by the user. This is extremely useful for big autogenerated schemas, that aggregate lots of subschemas and have functional bindings, given that it allows to show the user a simpler, non-error-prone form, also avoiding asking for unneeded data. -

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. -

sharp
High performance Node.js image processing module
The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, AVIF and WebP images of varying dimensions. Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips. Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available. Most modern macOS, Windows and Linux systems running Node.js v10+ do not require any additional install or runtime dependencies. This module supports reading JPEG, PNG, WebP, AVIF, TIFF, GIF and SVG images. Output images can be in JPEG, PNG, WebP, AVIF and TIFF formats as well as uncompressed raw pixel data. Streams, Buffer objects and the filesystem can be used for input and output.
