This is the marmelab/react-admin monorepo, a highly mature and widely-used frontend framework for building single-page admin panels in React and TypeScript. The repository is organized as a Lerna monorepo with core packages: `ra-core` (headless hooks, controllers, data provider abstraction, auth, i18n, store), `ra-ui-materialui` (all Material-UI based components for fields, inputs, lists, layouts, and buttons), and `react-admin` (umbrella entry point). It also includes scaffolding via `create-react-admin`, a no-code builder (`ra-no-code`), multiple data provider adapters (`ra-data-simple-rest`, `ra-data-graphql`, etc.), i18n packages (`ra-i18n-polyglot`, `ra-i18n-i18next`), and full-featured example applications (CRM, e-commerce demo, simple blog) that demonstrate real-world usage with authentication, filtering, theming, and offline support. Architecturally, the framework follows a clean separation of concerns: the core layer manages data fetching, authorization, navigation, and form state using React contexts and hooks, while the UI layer provides a comprehensive set of composable components. The data provider pattern abstracts any backend (REST, GraphQL, local storage) behind a uniform CRUD interface. The auth and i18n providers are similarly pluggable. The store abstraction (memory or localStorage) persists user preferences, selection, and saved queries. The routing is abstracted via a `RouterProvider` interface that supports React Router and TanStack Router. Over 26,000 GitHub stars and 5,400 forks attest to its community trust. The codebase exhibits strong engineering craftsmanship: extensive unit and integration tests (Jest, Cypress, Storybook), consistent use of TypeScript with generics, codemods for breaking changes, and a mature release process. The framework is actively maintained (dependabot, frequent releases, security patches) and remains well-aligned with its ecosystem (React 18, MUI v5, react-query v5, react-hook-form). Some deprecations and dual component implementations (Datagrid vs. DataTable) introduce minor friction, but overall this codebase is a gold standard for building enterprise admin UIs.

json-graphql-server is a TypeScript library and CLI that generates a fully functional GraphQL API from a plain JavaScript/JSON data object. At runtime it introspects the supplied data to infer GraphQL object types, filter input types, relationship fields, list queries, and mutations, then serves an executable schema through an Express middleware, a standalone CLI, or a browser-side XHR mock. The primary use case is fast prototyping and testing: developers provide an array of records per entity, and the tool immediately exposes queries like Post(id:), allPosts(page, perPage, sortField, sortOrder, filter), and _allPostsMeta, plus create/update/remove/delete mutations that mutate the in-memory data arrays. It is essentially json-server, but for GraphQL, and is designed to be used as a mock API or development fixture rather than a production data layer.

This repository provides a comprehensive component library for building admin dashboards and CRUD applications in React. It wraps react-admin's headless core (`ra-core`) with a shadcn/ui aesthetic, delivering over 80 reusable components including data table, forms, inputs, fields, buttons, layout elements, and a rich text editor. The architecture follows a provider pattern for data, authentication, and internationalization, making it backend-agnostic. It includes a demo e-commerce application, a Storybook for visual testing, a marketing website, and a shadcn registry for easy installation via the `shadcn add` command. The codebase is well-structured with extensive unit tests and documentation, though it depends on pre-release Base UI and several react-admin enterprise features that require a paid subscription.

This is a deprecated AngularJS 1.x demo application showcasing the ng-admin library for creating admin interfaces. It simulates an e-commerce poster shop ('Posters Galore') with mock data generated by Node.js scripts. The application uses FakeRest to create a mock REST API in the browser, allowing full CRUD operations on customers, products, orders, reviews, and settings without a real backend. The admin interface includes dashboards, custom directives for shopping cart calculations, currency formatting, and image zoom functionality. The repository is marked as archived in the README with a warning that it's no longer maintained.

ra-supabase is a TypeScript library that integrates react-admin with Supabase. It provides a dataProvider, an authProvider, and OpenAPI-schema-driven UI guessers, allowing developers to generate a complete admin interface from a Supabase project with minimal configuration. The dataProvider translates react-admin CRUD operations into Supabase REST queries, supporting pagination, sorting, filtering, and embedded relationships through a custom `@` syntax. The authProvider wraps Supabase Auth, handling email/password login, OAuth callbacks, password reset, and session management. The guessers fetch the Supabase OpenAPI schema and generate List, Show, Edit, and Create pages, or a full `<AdminGuesser>` scaffold.
