signpdf
Simple signing of PDFs in node
Formerly known as node-signpdf @signpdf is a family of packages trying to make signing of PDFs simple in Node.js. The main purpose of this package is to demonstrate the way signing can be achieved in a piece of readable code as it can take a lot of hours to figure out. When this repo was started we really wanted people to understand the signing flow. -

telegraf.js
Modern Telegram Bot Framework for Node.js
Bots are special Telegram accounts designed to handle messages automatically. Users can interact with bots by sending them command messages in private or group chats. These accounts serve as an interface for code running somewhere on your server. Telegraf is a library that makes it simple for you to develop your own Telegram bots using JavaScript or TypeScript. You can see in every example is a Context instance. Telegraf creates one for each incoming update and passes it to your middleware. It contains the update, botInfo, and telegram for making arbitrary Bot API requests, as well as shorthand methods and getters. Telegraf is written in TypeScript and therefore ships with declaration files for the entire library. Moreover, it includes types for the complete Telegram API via the typegram package. While most types of Telegraf's API surface are self-explanatory, there's some notable things to keep in mind. -

torrent-stream
The low level streaming torrent engine that peerflix uses
Torrent-stream is a core library that underpins peerflix (and similar tools), providing low-level torrent downloading and streaming capabilities in Node.js. It handles connecting to the BitTorrent swarm, negotiating peer connections, fetching torrent pieces, and exposing individual files inside a torrent as streams. This enables developers to build custom torrent-based applications — not just streaming video, but also file downloaders, partial-download managers, or peer-to-peer file distribution tools. The library supports selecting which files to download (useful in multi-file torrents), serves requested pieces on demand, and allows streaming large files without fully writing them to disk upfront — ideal for memory-efficient or on-the-fly consumption contexts. Because torrent-stream is a plain Node.js module, you can embed it in any JavaScript-based backend or tool, integrate it with HTTP servers to serve torrent content, or combine it with other processing pipelines. -

v8n
JavaScript fluent validation library
v8n aims to be the most fluent and simple validation library for use in any context. The API is beautifully readable and allows for easy creation of complex validations in any part of your app. Even though there are many useful default validation methods, it's a breeze to add your own fluent rules to v8n and use them anywhere in your app. The name v8n is actually derived from the structure of the word "validation". If you look closely you will find that between the v and the n, there are precisely 8 letters (a l i d a t i o). So we get from the sort of boring word validation to the very nice-looking acronym v8n. -

wavesurfer.js
Navigable waveform built on Web Audio and Canvas
wavesurfer.js is a customizable audio waveform visualization, built on top of Web Audio API and HTML5 Canvas. With wavesurfer.js you can create anything from an HTML5 audio player to a sophisticated DJ application. wavesurfer.js works only in modern browsers supporting Web Audio. It will fallback to Audio Element without graphics in other browsers (IE 11 and lower). You can also try wavesurfer.swf which is a Flash-based fallback. The audio will start playing as you press play. A thin line will be displayed until the whole audio file is downloaded and decoded to draw the waveform. Web Audio needs the whole file to decode it in the browser. You can however load pre-decoded waveform data to draw the waveform immediately. wavesurfer.js runs on modern browsers supporting Web Audio, including Firefox, Chrome, Safari (desktop and mobile) and Opera. -

web3.js Ethereum JavaScript API
Ethereum JavaScript API
Web3.js 4.x has been released. Checkout 4.x API documentation and migration guide for testing, early feedback and contributions. This is the Ethereum JavaScript API which connects to the Generic JSON-RPC spec. You need to run a local or remote Ethereum node to use this library. Additionally you can set a provider using web3.setProvider() (e.g. WebsocketProvider). We support types within the repo itself. Please open an issue here if you find any wrong types. If you are using create-react-app version >=5 you may run into issues building. This is because NodeJS polyfills are not included in the latest version of create-react-app. -

webpack DevServer
Serves a webpack app and updates the browser on changes
webpack-dev-server can be used to quickly develop an application. Options that are compatible with webpack-dev-middleware have a key icon next to them. This set of options is picked up by webpack-dev-server and can be used to change its behavior in various ways. When the server is started, there will be a message prior to the list of resolved modules. If you're using dev-server through the Node.js API, the options in devServer will be ignored. Pass the options as a second parameter instead: new WebpackDevServer(compiler, {...}). Be aware that when exporting multiple configurations only the devServer options for the first configuration will be taken into account and used for all the configurations in the array. HTML template is required to serve the bundle, usually it is an index.html file. Make sure that script references are added into HTML, webpack-dev-server doesn't inject them automatically. -

zeroshot CLI
Your autonomous engineering team in a CLI. Point Zeroshot at an issue
zeroshot CLI is an autonomous engineering agent orchestration CLI that lets developers point it at a software task or issue and have it plan, implement, validate, and iterate on code changes without direct manual intervention. It orchestrates a multi-agent workflow where separate roles such as planner, implementer, and independent validators collaborate in isolated environments, looping until the code meets acceptance criteria or produces reproducible failures. The tool supports multiple underlying AI providers like Claude Code, Codex, OpenCode, and Gemini, as well as integration with issue backends like GitHub, GitLab, Jira, and Azure DevOps, enabling flexible input sources and automation in diverse environments. Zeroshot manages isolation via git worktrees or Docker containers, which helps ensure that each agent’s work is reproducible and shielded from unwanted interference, and it persists crash-safe state so tasks can resume if interrupted. -
