Pagy is a high-performance, agnostic pagination library for Ruby web applications (Rails, Sinatra, Rack) and any Ruby collection. It provides multiple pagination techniques: offset, keyset (cursor-based), countless (no total count), countish (cached count), calendar (time-based), and search backend integrations (Elasticsearch, Meilisearch, Searchkick, Typesense). The gem includes a rich set of view helpers for pagination navigation (series, input, limit, info) with Bootstrap, Bulma, and Tailwind CSS support, plus client-side JavaScript for responsive and interactive navs. Its architecture is modular: paginators and helpers are loaded on demand via a deferred loading pattern, and abilities (shiftable, rangeable, countable, linkable) are composed into paginator classes. The codebase is thoroughly tested (100% line/branch coverage, unit, API, and E2E tests) and highly optimized for speed and memory. It also provides a CLI, dev tools (PagyWand for CSS customization, Pagy AI assistant), and extensive documentation. The library is not a data research project; it is a production-ready software component.
Buefy is a Vue 3 UI component library providing approximately 40+ Bulma-based components (buttons, inputs, tables, modals, datepickers, carousels, trees, etc.) that can be consumed individually or as a full bundle. It includes programmatic APIs for overlay components (dialog, toast, notification, snackbar, loading) and a global configuration system for icon packs, locale, and default behaviors. The library is published as the `buefy` npm package and is designed for tree-shaking via individual component registration. The architecture is a monorepo with two packages: `packages/buefy` (the library) and `packages/docs` (a Vite-based documentation site). Components are built using Vue 3 Options API with `defineComponent`, mixins for cross-cutting concerns (form validation, tabbed containers, notice behavior, compat fallthrough), and a consistent prop/event/slot pattern. SCSS styles are organized per component and leverage Bulma's CSS variable system for runtime theming. The library does not handle external data; it only manages UI state and provides a structured way to build Bulma-themed Vue 3 interfaces. Key entry points include `packages/buefy/src/index.ts` (main library export), `packages/buefy/src/utils/config.ts` (global configuration), and per-component index files that register each component as a Vue plugin. Data flows are limited to parent-child communication via provide/inject (e.g., Tabs, Steps, Table) and form element integration with a `BField` parent for validation. External dependencies include Vue 3 (>=3.4), Bulma CSS framework, and optional icon packs (Font Awesome, Material Design Icons). Build tooling uses Rollup, esbuild, Babel, and Vitest for testing.
