SamHatoum/pojo-observer

This system is a React-based file browser application that demonstrates a custom reactive state management library. It utilizes a minimalist object observer, implemented via JavaScript Proxies, to automatically trigger component re-renders when observed data changes. The codebase includes both the application logic for the file browser and the underlying 'pojo-observer' package, which provides the core observation utilities and React hooks for state synchronization.

The example directory now contains a complete, runnable file browser application. This includes React components (FileTree, FileContent, FileDetails, Workspace) that render a file list, content view, and details panel. The domain layer introduces domain classes (File, FileTree, FileContent, FileDetails) and event-based communication (FileSelectedEvent, FileUnselectedEvent) via a SimpleEventEmitter. A MemoryFileRepository provides mock data for demonstration purposes. The entry point (index.tsx) initializes the workspace service and renders the UI.

example · high confidence

Added a new \useObserver\ React hook and a \pureObserver\ utility that enable components to automatically re-render when observed JavaScript objects change. The implementation uses JavaScript Proxies to detect property and array mutations, supporting nested objects and arrays. A helper function \generateId\ is also introduced to manage internal state tracking. Comprehensive test suites verify the observer's behavior with single objects, multiple objects, and nested structures.

src · high confidence

A new step-definition file was added to support BDD-style testing of the file tree feature. The file defines Gherkin steps for loading files into the tree, selecting files, and verifying file content and details, enabling automated verification of these user flows.

The project introduces a new npm package named 'pojo-observer', described as a minimalist object observer for React hooks. The package includes TypeScript definitions, Babel configuration for building the library, and a suite of development dependencies including Jest, ESLint, and testing libraries. It establishes the foundational structure for the library, including peer dependencies on React (\>= 16.8.0) and various tooling for linting, testing, and semantic release.
