HLS.js
HLS.js is a JavaScript library that plays HLS in browsers
HLS.js is a JavaScript library that implements an HTTP Live Streaming client. It relies on HTML5 video and MediaSource Extensions for playback. It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a Web Worker when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016. HLS.js works directly on top of a standard HTML<video> element. HLS.js is written in ECMAScript6 (*.js) and TypeScript (*.ts) (strongly typed superset of ES6), and transpiled in ECMAScript5 using Babel and the TypeScript compiler. Webpack is used to build the distro bundle and serve the local development environment. -

SurveyJS
JavaScript Survey and Form Library
SurveyJS Form Library is distributed as npm packages and as scripts and style sheets that you can reference on your page. You can use it in any React, Angular, Vue, Knockout, or jQuery application. React, Angular, Knockout, and Vue3 are supported natively. To communicate with the server, the libraries use JSON objects that represent form schemas (content and layout of a form) and form results (answers). You have the option to build dynamic JSON-driven forms using our free full-featured form builder demo available on the website. Alternatively, you can integrate the form builder library and create forms using a drag-and-drop UI directly within your own application. With years of development and support behind us, we've assisted hundreds of companies across various industries. With Survey, you can create nearly anything that popular cloud services offer. Furthermore, our library is fully extensible, allowing you to modify its behavior to suit your specific needs. -

visx
Visualization components
visx a collection of expressive, low-level visualization primitives for React. At Airbnb, we made it a goal to unify our visualization stack across the company and in the process, we created a new project that brings together the power of D3 with the joy of React. visx is split into multiple packages. Start small and use only what you need. Bring your own state management, animation library, or CSS-in-JS solution. Odds are good your React app already has an opinion on how animation, theming, or styling is done. visx is careful not to add another one and integrates with all of them. As you start using visualization primitives, you’ll end up building your own charting library that’s optimized for your use case. You’re in control. And most importantly, it’s just React. If you know React, you can make visualizations. It’s all the same standard APIs and familiar patterns. visx should feel at home in any React codebase. -

SWR
React Hooks library for remote data fetching
The name “SWR” is derived from stale-while-revalidate, a HTTP cache invalidation strategy popularized by HTTP RFC 5861. SWR is a strategy to first return the data from cache (stale), then send the fetch request (revalidate), and finally come with the up-to-date data. With SWR, components will get a stream of data updates constantly and automatically. And the UI will be always fast and reactive. With just one single line of code, you can simplify the logic of data fetching in your project, and also have all many amazing features out-of-the-box. SWR has you covered in all aspects of speed, correctness, and stability to help you build better experiences. Fast page navigation, polling on interval, data dependency, revalidation on focus, revalidation on network recovery, local mutation (Optimistic UI), smart error retry, pagination and scroll position recovery, React Suspense, and more. -

Countries, Languages & Continents data
Countries, Languages & Continents data (capital and currency)
Continents & countries (with languages, capital and currency, native name, calling codes).

Also, contains separate JSON files with additional country Emoji flags data. This version changes a lot in the data structures and placement of the files. So, if your projects depend on the old structure — specify previous versions, <2.0.0. Country item languages field is an Array in JSON files to easily count and match items with a Language item. But currency and phone calling codes may be a comma-separated String. Languages list only contains languages used in Countries data. Full list of known languages is exported as languagesAll from ./dist/languages.all.json. -

Formik
Build forms in React
Formik is the world's most popular open-source form library for React and React Native. Formik takes care of the repetitive and annoying stuff, keeping track of values/errors/visited fields, orchestrating validation, and handling submission, so you don't have to. This means you spend less time wiring up state and change handlers and more time focusing on your business logic. No fancy subscriptions or observables under the hood, just plain React state and props. By staying within the core React framework and away from magic, Formik makes debugging, testing, and reasoning about your forms a breeze. If you know React, and you know a bit about forms, you know Formik! Since form state is inherently local and ephemeral, Formik does not use external state management libraries like Redux or MobX. This also makes Formik easy to adopt incrementally and keeps bundle size to a minimum. -

Google APIs Node.js Client
Google's supported Node.js client library
Google's supported Node.js client library for accessing Google APIs. Support for authorization and authentication with OAuth 2.0, API Keys and JWT (Service Tokens) is included. The full list of supported APIs can be found on the Google APIs Explorer. The API endpoints are automatically generated, so if the API is not in the list, it is currently not supported by this API client library. These client libraries are supported by Google. However, these libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features. For Google Cloud Platform APIs, we recommend using google-cloud-node which is under active development. This library supports the maintenance LTS, active LTS, and current release of node.js. -

Got
Human-friendly and powerful HTTP request library for Node.js
Got implements RFC 7234 compliant HTTP caching which works out of the box in-memory and is easily pluggable with a wide range of storage adapters. Got uses Keyv internally to support a wide range of storage adapters. For something more scalable you could use an official Keyv storage adapter. Hooks allow modifications during the request lifecycle. Hook functions may be async and are run serially. Got will make no further changes to the request before it is sent. This is especially useful in conjunction with got.extend() when you want to create an API client that, for example, uses HMAC-signing. You can override the request function by returning a ClientRequest-like instance or a IncomingMessage-like instance. This is very useful when creating a custom cache mechanism. The response object will typically be a Node.js HTTP response stream, however, if returned from the cache it will be a response-like object which behaves in the same way. -

Iconoir
An open source icons library with 1K+ icons
Iconoir is an open-source library with 1000+ unique SVG icons, designed on a 24x24 pixels grid. No premium icons, no email sign-up, no newsletters. A React library is available to install under the name iconoir-react. A Flutter library is available to install under the name iconoir_flutter. Iconoir is happily part of Framer now. To start using the icons, on the top menu, Insert > Graphics > Iconoir. You can switch between icons from the right sidebar in the editor. The class must always be "iconoir-" and then the name of the icon. The icons are display: inline-block and default to the current font size. You can control this by adjusting the ::before styles of the element. -
