    Fabric

    Fabric

    Fabric is an open-source framework for augmenting humans using AI

    Fabric is a command-line framework that turns a curated library of prompt “patterns” into reusable, automatable workflows for large language models. Instead of repeatedly crafting ad-hoc prompts, you pick a pattern (for research, summarization, brainstorming, code review, and more) and feed it inputs or files. The tool standardizes execution with configuration files and environment variables, enabling reproducible runs across different models and providers. Patterns can be customized with variables, chained into pipelines, and applied to entire directories, which helps scale editorial or analytical tasks. A growing catalog of community patterns serves as a knowledge base for effective prompt engineering in practical contexts. In short, Fabric makes LLM work predictable and scriptable, so teams can share methods rather than one-off prompts.

    GSD Core

    GSD Core

    Meta-prompting, context engineering, spec-driven development system

    GSD Core is the core framework behind Open GSD, a workflow system for AI-assisted software engineering. It is designed to keep agent-driven development organized by turning vague goals into structured research, plans, tasks, implementation phases, verification steps, and handoffs. The project focuses on cleaner context, verified work, and more honest project history when working with coding agents. It supports installation across several AI coding runtimes and offers profiles for different levels of workflow surface area. The system is especially useful for developers who use AI agents heavily and need more discipline around planning, execution, and review. It acts less like a single app and more like an execution layer for shipping software with agents.

    Gloria

    Gloria

    Gloria is a static website generator, based on NodeJS

    V2 is deprecating lots of old functions, make sure to read the migrating docs. We're also slowly moving into typescript, and while I think it should work very well for your projects, legally I need to remind you that this is a satire of other projects. It currently supports having a content management system using MD files and tailwind CSS, with some bugs, but the main functionality and philosophy have been accomplished. This project aims to be a substitute for Jekyll, to help you create static websites without depending on Ruby. Because of its ease of use, extensibility, and support for md files, is also great for creating websites out of documentation that lives in a source code.

    GraphQL.js

    GraphQL.js

    A reference implementation of GraphQL for JavaScript

    The JavaScript reference implementation for GraphQL, a query language for APIs created by Facebook. GraphQL.js is a general-purpose library and can be used both in a Node server and in the browser. As an example, the GraphiQL tool is built with GraphQL.js! Building a project using GraphQL.js with webpack or rollup should just work and only include the portions of the library you use. This works because GraphQL.js is distributed with both CommonJS (require()) and ESModule (import) files. Ensure that any custom build configurations look for .mjs files! For practical applications, you'll probably want to run GraphQL queries from an API server, rather than executing GraphQL with a command line tool. GraphQL.js provides two important capabilities: building a type schema and serving queries against that type schema.

    HTM

    HTM

    JSX alternative using standard tagged templates, with compiler support

    htm is JSX-like syntax in plain JavaScript, no transpiler necessary. Develop with React/Preact directly in the browser, then compile htm away for production. It uses standard JavaScript Tagged Templates and works in all modern browsers. The syntax you write when using HTM is as close as possible to JSX. htm actually takes the JSX-style syntax a couple steps further! No transpiler necessary. HTML's optional quotes: <div class=foo>. Component end-tags: <${Footer}>footer content<//>. Syntax highlighting and language support via the lit-html VSCode extension and vim-jsx-pretty plugin. Multiple root element (fragments): <div /><div />. Support for HTML-style comments: <div><!-- comment --></div>. htm is published to npm, and accessible via the unpkg.com CDN. If you're using Preact or React, we've included off-the-shelf bindings to make your life easier. They also have the added benefit of sharing a template cache across all modules.

It's meant to be served by an HTTP server, it will not work if you open the index.html directly over file:// protocol. Title, icons, links, colors, and services can be configured in the config.yml file (located in /assets directory once built, or in the public/assets directory in development mode), using yaml format. null value or missing keys will be ignored and value from the config.yml will be used if available. Empty values (either in config.yml or the endpoint data) will hide the element.

    Inquirer.js

    Inquirer.js

    A collection of common interactive command line user interfaces

    Inquirer.js strives to be an easily embeddable and beautiful command line interface for Node.js (and perhaps the "CLI Xanadu"). Inquirer.js should ease the process of providing error feedback, asking questions, parsing input, validating answers, and managing hierarchical prompts. Inquirer.js provides the user interface and the inquiry session flow. If you're searching for a full blown command line program utility, then check out commander, vorpal or args. Create a self contained inquirer module. If you don't want to affect other libraries that also rely on inquirer when you overwrite or add new prompt types. Internally, Inquirer uses the JS reactive extension to handle events and async flows. This mean you can take advantage of this feature to provide more advanced flows. For example, you can dynamically add questions to be asked.

    Isotope

    Isotope

    Filter and sort layouts

    Include the Isotope .js file in your site. Isotope works on a container element with a group of similar child items. All sizing of items is handled by your CSS. You can use Isotope as a jQuery plugin. You can use Isotope with vanilla JS. You can initialize Isotope in HTML, without writing any JavaScript. All options are optional, but itemSelector is recommended. Layout modes have their own separate options. We recommend always setting itemSelector. itemSelector is useful to exclude sizing elements or other elements that are not part of the layout. If you want to use Isotope to develop commercial sites, themes, projects, and applications, the Commercial license is the appropriate license. With this option, your source code is kept proprietary. If you are creating an open source application under a license compatible with the GNU GPL license v3, you may use Isotope under the terms of the GPLv3.

    Jest Puppeteer

    Jest Puppeteer

    Run your tests using Jest & Puppeteer

    Most continuous integration platforms limit the number of threads one can use. If you have more than one test suite running puppeteer chances are that your test will timeout. This is because jest will try to run puppeteer in parallel and the CI platform won't be able to handle all the parallel jobs in time. A fix to this is to run your test serially when in a CI environment. Users have discovered that running test serially in such environments can render up to 50% of performance gains. Writing integration test can be done using Puppeteer API but it can be complicated and hard because API is not designed for testing. Debugging tests can be hard sometimes and it is very useful to be able to pause tests in order to inspect the browser. Jest Puppeteer exposes a method jestPuppeteer.debug() that suspends test execution and gives you the opportunity to see what's going on in the browser.

    Lebab

    Lebab

    Turn your ES5 code into readable ES6

    Turn your ES5 code into readable ES6. Lebab does the opposite of what Babel does. Lebab transpiles your ES5 code to ES6/ES7. It does exactly the opposite of what Babel does. Convert your old-fashioned code using the lebab cli tool, enabling a specific transformation. The recommended way of using Lebab is to apply one transform at a time, read what exactly the transform does and what are its limitations, apply it to your code and inspect the diff carefully. Transforms can be applied with relatively high confidence. They use pretty straightforward and strict rules for changing the code. The resulting code should be almost 100% equivalent to the original code. Transforms should be applied with caution. They either use heuristics that can't guarantee that the resulting code is equivalent of the original code, or they have significant bugs which can result in breaking your code.

    LemonadeJS

    LemonadeJS is a 7KB reactive JavaScript micro-library

    LemonadeJS is an ultra-lightweight, reactive JavaScript micro-library that makes building dynamic user interfaces simple and intuitive by providing two-way data binding and component reactivity without any external dependencies or build steps. At roughly 5–7 KB, it works directly in the browser or with bundlers like webpack, enabling developers to create reusable, reactive UI components using pure JavaScript, JSX, or TypeScript while avoiding heavy frameworks. Its core reactivity system tracks changes to component state and efficiently updates only the affected parts of the DOM, which improves performance for both small widgets and larger applications. The library also offers powerful template syntax and lifecycle hooks so you can manage state, effects, loops, and events in a clear and expressive way while keeping your code close to native JavaScript.
