prettier-eslint
Formats your JavaScript using prettier followed by eslint --fix
The fix feature of eslint is pretty great and can auto-format/fix much of your code according to your ESLint config. prettier is a more powerful automatic formatter. One of the nice things about prettier is how opinionated it is. Unfortunately, it's not opinionated enough and/or some opinions differ from my own. So after prettier formats the code, I start getting linting errors. This formats your code via prettier, and then passes the result of that to eslint --fix. This way you can get the benefits of prettier's superior formatting capabilities, but also benefit from the configuration capabilities of eslint. The path of the file being formatted can be used to override eslintConfig (eslint will be used to find the relevant config for the file). -

pretty-quick
Get Pretty Quick
Runs Prettier on your changed files. Pre-commit mode. Under this flag only staged files will be formatted, and they will be re-staged after formatting. Partially staged files will not be re-staged after formatting and pretty-quick will exit with a non-zero exit code. The intent is to abort the git commit and allow the user to amend their selective staging to include formatting fixes. When not in staged pre-commit mode, use this flag to compare changes with the specified branch. Defaults to master (git) / default (hg) branch. Do not resolve prettier config when determining which files to format, just use standard set of supported file types & extensions prettier supports. This may be useful if you do not need any customization and see performance issues. Check that files are correctly formatted, but don't format them. This is useful on CI to verify that all changed files in the current branch were correctly formatted. -

pseudocode.js
Beautiful pseudocode for the Web
pseudocode.js is a JavaScript library that typesets pseudocode beautifully to HTML. Pseudocode.js takes a LaTeX-style input that supports the algorithmic constructs from LaTeX's algorithm packages. With or without LaTeX experience, a user should find the grammar fairly intuitive. The HTML output produced by pseudocode.js is (almost) identical to the pretty algorithms printed on publications that are typeset by LaTeX. Inserting math formulas in pseudocode.js is as easy as LaTeX. Just enclose the math expression in $...$ or \(...\). -

rep+
Burp-style HTTP Repeater for Chrome DevTools with built‑in AI
rep+ is a lightweight browser extension for Chrome DevTools that brings a Burp Suite-style HTTP repeater directly into the developer console, enhanced with built-in AI to help explain requests and suggest tests. It captures HTTP traffic from the inspected page without needing a proxy, allowing users to replay, modify, and analyze individual requests with fine-grained control over headers, bodies, and methods. The tool offers hierarchical grouping, tagging, and filtering of captured requests so that developers and security testers can manage complex traffic flows efficiently. It includes AI-assisted insights, where contextual explanations and attack vector suggestions help interpret request outcomes or propose modifications. Additional productivity features like exporting/importing requests, various representation modes (pretty/raw/hex), and bulk replay mechanisms make it suitable for debugging, performance checking, or security probing. -

super-agent-party
All-in-one AI companion! Desktop girlfriend + virtual streamer
Super Agent Party is an open-source experimental framework designed to demonstrate collaborative multi-agent AI systems interacting within a shared environment. The project explores how multiple specialized AI agents can coordinate to solve complex tasks by communicating with each other and sharing information. Instead of relying on a single monolithic model, the framework organizes agents with different roles or capabilities that cooperate to achieve goals. Each agent may handle different responsibilities such as planning, execution, reasoning, or knowledge retrieval, allowing the system to tackle more complex problems than a single agent might handle alone. The platform is primarily intended as a research and demonstration environment for experimenting with agent collaboration strategies. Developers can use it to study coordination patterns, communication protocols, and task decomposition in multi-agent systems. -

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. -

undici
An HTTP/1.1 client, written from scratch for Node.js
An HTTP/1.1 client, written from scratch for Node.js. This section documents our most commonly used API methods. Additional APIs are documented in their own files within the docs folder and are accessible via the navigation list on the left side of the docs site. Garbage collection in Node is less aggressive and deterministic (due to the lack of clear idle periods that browsers have through the rendering refresh rate) which means that leaving the release of connection resources to the garbage collector can lead to excessive connection usage, reduced performance (due to less connection re-use), and even stalls or deadlocks when running out of connections. -

validatorjs
A data validation library in JavaScript for the browser and Node.js
The validatorjs library makes data validation in JavaScript very easy in both the browser and Node.js. This library was inspired by the Laravel framework's Validator. -

vis-network
Display dynamic, automatically organised, customizable network views
Network is a visualization to display networks and networks consisting of nodes and edges. The visualization is easy to use and supports custom shapes, styles, colors, sizes, images, and more. The network visualization works smooth on any modern browser for up to a few thousand nodes and edges. To handle a larger amount of nodes, Network has clustering support. Network uses HTML canvas for rendering. As of 4.0, the network consists of individual modules which handle specific parts of the network. These modules have their own docs, options, methods and events which you can access by clicking on the modules. -

vue-chartjs
Vue.js wrapper for Chart.js
vue-chartjs is a wrapper for Chart.js in vue. You can easily create reusable chart components. You can use vue-chartjs directly in the browser without any build setup. Like in this codepen. For this case, please use the vue-chartjs.min.js which is the minified version. You also need to add the Chart.js CDN script. Chart.js does not update or re-render the chart if new data is passed. However, you can simply implement this on your own or use one of the two mixins which are included. The mixins automatically create chartData as a prop or data. And add a watcher. If data has changed, the chart will update. However, keep in mind the limitations of vue and javascript for mutations on arrays and objects. It is important that you pass your options in a local variable named options! You can create your components in Vues single file components. -

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. -

why-is-node-running
For when Node is running but you don't know why
why-is-node-running is a diagnostic tool for Node.js developers that helps answer the question: “why is my Node.js process still alive?” In complex asynchronous code — with timers, open handles, network sockets, file watchers, or unfulfilled promises — it can be tricky to figure out what is preventing the event loop from exiting. This utility inspects the active handles and resources in the runtime, prints a breakdown of open callbacks, sockets, timers, and other tasks, and explains what’s keeping Node running, helping you track down leaks or unintended resource retention. It’s particularly useful during testing, when you expect Node to exit after tests finish, or in long-running servers when you're debugging resource leaks or shutdown logic. By providing clear human-readable output that lists current handles and their origins, the tool dramatically reduces the time you would otherwise spend manually instrumenting your code. -

xmpp.js
XMPP for JavaScript
xmpp.js is a JavaScript library for the Extensible Messaging and Presence Protocol (XMPP), facilitating real-time communication features like instant messaging and presence information. -
24
zx
A tool for writing better scripts
Bash is great, but when it comes to writing scripts, people usually choose a more convenient programming language. JavaScript is a perfect choice, but the standard Node.js library requires additional hassle before use. The zx package provides useful wrappers around child_process, escapes arguments, and gives sensible defaults. Write your scripts in a file with .mjs extension in order to be able to use await on top level. If you prefer the .js extension, wrap your scripts in something like void async function. -
