AlaSQL
JavaScript SQL database for browser and Node.js for relational tables
AlaSQL.js - JavaScript SQL database for browser and Node.js. Handles both traditional relational tables and nested JSON data (NoSQL). Export, store, and import data from localStorage, IndexedDB, or Excel. We focus on speed by taking advantage of the dynamic nature of JavaScript when building up queries. Real-world solutions demand flexibility regarding where data comes from and where it is to be stored. We focus on flexibility by making sure you can import/export and query directly on data stored in Excel (both .xls and .xlsx), CSV, JSON, TAB, IndexedDB, LocalStorage, and SQLite files. The library adds the comfort of a full database engine to your JavaScript app. No, really - it's working towards a full database engine complying with most of the SQL-99 language, spiced up with additional syntax for NoSQL (schema-less) data and graph networks. -

Alpine.js
A rugged, minimal framework for composing JavaScript behavior
Alpine.js is a lightweight JavaScript framework designed to bring declarative, reactive behavior directly into HTML markup, functioning similarly in spirit to Vue but with a much smaller footprint. It’s often described as “jQuery for the modern web,” enabling you to sprinkle interactivity onto static HTML without needing a full SPA framework. You use directives like x-data, x-bind, x-on, x-if, and others to attach reactive state, event listeners, and conditional rendering straight in the DOM. Because Alpine is so minimal, it avoids virtual DOM overhead and focuses on being incremental and composable; you can use it for small interactive components inside traditional server-rendered pages. The project has grown a robust ecosystem (plugins, devtools, helper libraries) as people adopt it for micro-frontend patterns, admin panels, interactive widgets, and anything that benefits from having bits of reactivity without a heavy JavaScript framework. -

Calibre-Web Automated
Calibre-Web but Automated and with tons of New Features
Calibre-Web-Automated (CWA) is an all-in-one, self-hosted solution for managing an ebook library that combines the modern, lightweight web UI style of Calibre-Web with the deeper tooling and conversion capabilities associated with Calibre. The goal is to reduce the common “two-service” setup where users run Calibre-Web for browsing and Calibre separately for conversions, metadata fixes, and automation, by packaging those workflows together in a single system. CWA keeps the familiar strengths of Calibre-Web, like a responsive interface, OPDS feeds for e-readers, and strong user/permission management, while layering in extensive automation features that handle ingest, conversion, metadata enforcement, and library organization with less manual effort. It also expands authentication options (including modern OAuth/OIDC flows) and adds quality-of-life improvements such as enhanced search/filtering, multi-language UI support, and better device-centric workflows for sending to e-readers. -

Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -

CodeCopy
A browser extension that adds copy to clipboard buttons
CodeCopy is a browser extension that automatically adds “copy to clipboard” buttons to code blocks on popular documentation and Q&A sites. Its goal is to save developers time and frustration by making it a single click to copy example snippets, rather than manually selecting text and dealing with formatting issues. The extension detects code snippets on pages like GitHub, MDN, Gist, Stack Overflow, StackExchange, npm, Medium, and others, then overlays a small copy icon or button in the corner of each block. When a user clicks the button, codecopy uses the Clipboard API (or fallbacks) to copy the snippet to the clipboard with minimal visual noise or disruption. The repository provides the extension source, manifest, and build pipeline so that developers can contribute new site matchers or customize behavior. It is distributed under an MIT license and is available for multiple browsers, including Chrome, Firefox, and Opera. -

Consola
Elegant Console Logger for Node.js and Browser
Fancy output with fallback for minimal environments. Consistent command-line interface (CLI) experience. Spam prevention by throttling logs. console uses std in the underlying so calling wrapStd redirects console too. The benefit of this function is that things like console.info will be correctly redirected to the corresponding type. Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without the need for extra effort. Choose between one of the built-in reporters or bring in your own one. By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs. A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look at the linked implementations. -

Email Templates
Create, preview, and send custom email templates for Node.js
Create, preview, and send custom email templates for Node.js. Highly configurable and supports automatic inline CSS, stylesheets, embedded images and fonts, and much more! Made for sending beautiful emails with Lad. We've added preview email by default to this package! If you run into any issues with configuration, files, templates, locals, etc, then you can use the DEBUG environment flag. You can swap the transport option with a Nodemailer transport configuration object or transport instance. We highly recommend using Postmark for your transport (it's the default in Lad). Out of the box, templates are cached as they are compiled (e.g. as emails are sent, the template they're using is cached). However these templates are not cached in advance, so the first emails sent of each template will be slower to send. We strongly suggest to pre-cache your templates with cache-pug-templates (if you're using the default Pug template engine). -

Gitrob
Scans GitHub repositories for potentially sensitive files
Gitrob is an open source reconnaissance tool designed to identify potentially sensitive files that have been committed to public GitHub repositories. It helps security professionals, researchers, and organizations detect accidental data exposure by scanning repositories associated with specific GitHub users or organizations. The tool works by cloning repositories and analyzing their commit history to search for files that match predefined signatures of sensitive data. These signatures are used to flag items such as credentials, private keys, configuration files, and other materials that may expose confidential information. By automatically inspecting repository histories, Gitrob simplifies the process of identifying security risks that might otherwise remain unnoticed in publicly accessible codebases. The results of the scan are presented through a built-in web interface that allows users to browse findings, review flagged files, and analyze potential leaks more efficiently. -

IPLD Explorer Components
React components for ipfs-webui
React components for ipfs-webui. This module was extracted from explore.ipld.io so it could be reused from the IPFS Web UI. This module is not intended to be re-used in it's current form by other projects. There is more work to do to make this a nice set of generic components. The ES5-friendly version of the src dir is generated to the dist dir and the page components are all provided as named exports so you can import them. There are peer dependencies so that the parent app can pick the versions of common deps. You'll need to add relevant deps to your project. These components use redux-bundler and your app will need to use a redux-bundler provider in order to propagate the properties and selectors. You can find a basic example of this in ./dev/devPage.jsx. -

Layui UI
An open source Web UI component library
layui is a set of open-source Web UI component library, which adopts its own classic modularization specifications and follows the development method of native HTML/CSS/JS. It is very easy to use and ready to use. Its style is simple and light, while its components are elegant and rich. Every detail from source code to usage method has been carefully crafted, which is very suitable for the rapid development of web interface. Layui is different from those front-end frameworks based on the bottom layer of MVVM, but it does not go against the road, but believes in returning to the basics. To be precise, it is more for back-end developers. You don’t need to get involved in various front-end tools. You only need to face the browser itself, and let all the elements and interactions you need come from here at your fingertips.
