TikTok Live Connector
Node.js library to receive live stream events
TikTok Live Connector is a Node.js library for receiving real-time TikTok LIVE events from TikTok’s internal Webcast push service. It can connect to a live stream by username and listen for events such as comments, gifts, member joins, follows, shares, questions, likes, subscriptions, viewer updates, and battles. The library does not require user credentials for basic live chat connection, which makes it useful for overlays, chat readers, bots, dashboards, alerts, and livestream interaction tools. It is a reverse-engineering project rather than an official TikTok production API, so developers should expect platform changes and occasional breakage. Recent development has focused on a more modular TypeScript architecture and expanded event schema support. It is best used for experiments, prototypes, creator tools, and non-critical realtime TikTok LIVE integrations. -

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. -

This library is provided as UMD (Universal Module Definition) and ES6 module. When you modify width or height of a canvas, it will be automatically cleared by the browser. SignaturePad doesn't know about it by itself, so you can call signaturePad.clear() to make sure that signaturePad.isEmpty() returns correct value in this case. -

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. -

carbon-components-svelte
Svelte implementation of the Carbon Design System
Carbon Components Svelte is a Svelte-native implementation of IBM’s Carbon Design System, built to bring the structure, consistency, and scalability of a mature enterprise design system into Svelte applications. Rather than being a small collection of ad hoc widgets, it functions as a comprehensive component library intended to support design reuse, predictable development, and long-term extensibility across products. Because it is tied to Carbon, the project is especially valuable for teams that want a well-established visual language and interaction model instead of inventing one from scratch. The library also sits within a broader Carbon Svelte ecosystem that includes icon components, pictograms, charts, and preprocessors, which makes it possible to assemble full product interfaces with a unified design vocabulary. Its styling model supports multiple official themes. -

ts-blank-space
A small, fast, pure JavaScript type-stripper
ts-blank-space is a fast type-stripping compiler that converts TypeScript to JavaScript. It supports a modern subset of TypeScript by erasing the types and replacing them with whitespace. That's it. It is not a type checker and does not perform any other code transformations. The underlying technique can improve build performance and simplify development. The implementation is pure TypeScript. It is simple enough to read and understand in a few minutes because it is only 700 lines of code and reuses the original TypeScript parser. The core idea is to use spaces as a substitute for type annotations. You can think of ts-blank-space as a reference implementation of this type-stripping technique. Much like other compiler techniques seen in the JavaScript ecosystem, such as tree-shaking, it is a reusable idea that any TypeScript compiler could implement. -

Driver.js
A lightweight, dependency-free JavaScript library
Driver.js is a lightweight, framework-agnostic JavaScript library for building guided tours, feature spotlights, and product walkthroughs. It programmatically highlights elements on a page, dims the background, and attaches callouts so users learn new flows without leaving the UI. The API lets you define steps, order, and behavior, while handling positioning, scrolling, and viewport collisions gracefully. It strives to be unobtrusive: tours can be triggered contextually, resumed, or dismissed without hijacking the app. Accessibility and keyboard interaction are considered so tours remain usable beyond simple mouse clicks. Because it has no hard dependency on a specific framework, it integrates into vanilla JS apps or modern stacks alike.
