    HLS.js

    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.

It’s useful for privacy newcomers planning a gradual migration as well as experts building a hardened toolchain. The project also surfaces learning resources and practical guidance so you can understand the broader privacy landscape, not just pick tools in isolation.

    Groq TypeScript / Node.s

    Groq TypeScript / Node.s

    The official Node.js / Typescript library for the Groq API

    Groq TypeScript / Node.s (also often referred to as “groq-sdk” on npm) is the official Node.js / TypeScript client library for Groq’s REST API, enabling JavaScript/TypeScript developers to integrate LLM and AI-powered services into web backends, serverless functions, or frontend apps. It exports strongly-typed interfaces for models, chat completions, file uploads (e.g. for audio transcription), and other endpoints, allowing for better type safety and developer experience when using Groq from TypeScript. The library also supports passing different input types (file streams, blobs, fetch responses) for media-related endpoints, making it flexible for diverse environments (backend, browser, serverless). With this SDK, developers can call Groq’s models, transcribe audio, perform file uploads — all with minimal boilerplate — which streamlines creation of AI-enabled applications in the JavaScript/TypeScript ecosystem.

Ionicons was made for Ionic Framework, a cross-platform hybrid and Progressive Web App framework. The Ionicons Web Component is an easy and performant way to use Ionicons in your app. The component will dynamically load an SVG for each icon, so your app is only requesting the icons that you need. Also note that only visible icons are loaded, and icons which are "below the fold" and hidden from the user's view do not make fetch requests for the svg resource. If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary.
