GridStack.js is a production-grade TypeScript library for building responsive, drag-and-drop dashboard layouts. The core GridStack class manages widget lifecycle, DOM placement, responsive column switching, nested grids, serialization, and eventing, while GridStackEngine performs collision and positioning math without touching the DOM. The library ships its own drag-and-drop subsystem rather than depending on HTML5 drag-and-drop or jQuery, and it has zero runtime dependencies. Architecturally, the repository is a multi-package collection: a framework-agnostic core, a SCSS styling layer, and official Angular, React, and Vue wrappers. The wrappers integrate through callback hooks such as addRemoveCB, saveCB, and updateCB, plus DOM-stamped host APIs, allowing each framework to dynamically create and destroy widgets while keeping item content mounted during cross-grid drags. Demo applications under demo/, angular/projects/demo, react/src, and vue/src exercise the public API and serve as integration references. The project is actively maintained with a comprehensive Vitest and Playwright test suite, issue-numbered regression tests, and frequent releases. Its main technical debt is the large monolithic gridstack.ts (roughly 3100 lines) and the need to keep three framework wrappers synchronized with core API changes. The Angular wrapper is intentionally pinned to an older Angular major and some legacy build artifacts remain, but the core engine/UI separation, clean utility layer, and callback-based framework integration make many parts genuinely reusable.
Pure is a minimal, responsive CSS library that provides a set of small, modular styles for base HTML elements, grids, buttons, forms, menus, and tables. It builds on Normalize.css for cross-browser consistency and follows SMACSS conventions for easy customization. The repository contains the source CSS files, a Grunt-based build system that generates minified and prefixed bundles, and a Docusaurus documentation site. The library is production-ready, extremely lightweight (3.7KB gzipped), and designed to be a starting point for any web project without imposing a specific look.
