Jsondiffpatch
jsondiffpatch es una librería de diff y patch para JSON diseñada para calcular las diferencias entre dos objetos JSON y aplicar esos cambios para sincronizar estados. Funciona como una herramienta de sincronización para calcular deltas y aplicar parches para actualizar o revertir objetos complejos de JavaScript anidados.
El proyecto proporciona una implementación compatible con el estándar RFC 6902 JSON Patch para actualizaciones atómicas y un renderizador de diferencias visuales que convierte los deltas de datos en vistas HTML legibles por humanos. Incluye una herramienta de diff de texto especializada para realizar análisis detallados a nivel de carácter en cadenas largas dentro de valores de datos JSON.
La librería cubre una amplia gama de capacidades, incluyendo la generación recursiva de deltas y el cálculo de diferencias de arrays utilizando algoritmos de subsecuencia común más larga (LCS). Admite el diffing lógico de arrays para detectar movimientos de elementos mediante hashing personalizado y ofrece opciones de salida multiformato, como formato de consola codificado por colores y un componente de React dedicado para comparaciones visuales.
Features
- JSON Diff Tools - Calculates differences between two JSON structures to identify specific changes in content and hierarchy.
- JSON Difference Computation - Calculates the delta between two JSON objects to identify the specific changes needed to transform one into the other.
- JSON Patching - Provides a standard-compliant implementation of RFC 6902 JSON Patch for atomic updates.
- JSON State Synchronizers - Computes deltas and applies patches to synchronize, update, or revert complex nested JavaScript objects.
- Recursive Delta Generation - Traverses nested JSON structures to produce a hierarchical tree of modifications representing deep differences.
- Data Difference Renderers - Converts data deltas into human-readable HTML views with highlighted additions and deletions.
- Data Diff Viewers - Renders visual HTML or text representations of differences between two complex JSON datasets for human review.
- JSON State Synchronization - Updates target JSON objects by applying calculated deltas to synchronize states.
- LCS-Based Sequence Diffing - Implements the Longest Common Subsequence algorithm to identify additions and deletions within JSON arrays.
- Array Sequence Diffing - Uses the Longest Common Subsequence algorithm to identify added, removed, or modified items within arrays.
- State-to-HTML Rendering - Converts internal delta states directly into HTML structures for browser display.
- Complex Array Diffing - Identifies moved, added, or deleted items within JSON arrays using custom hashing instead of simple index matching.
- Logical Array Diffing - Matches objects within arrays using custom hash functions to detect moves and deletions instead of relying on position.
- Multi-Format Serializers - Transforms internal diff structures into multiple representations, including RFC 6902 JSON Patch and annotated HTML.
- Undo-Redo State History - Provides a mechanism to track state transitions for reversing and reapplying changes to JSON objects.
- Character-Level Text Diffing - Includes a specialized tool for performing fine-grained, character-level analysis on long strings within JSON values.
- Text Differencing - Performs fine-grained character-level analysis on long strings within JSON data values.
- Change Reversions - Provides utilities to undo the effects of a delta or generate reverse deltas to restore previous states.
- Array Item Move Detection - Identifies when an element has changed position within an array and records the destination index in the delta.
- Character-Level Diffing - Uses differencing algorithms that treat each Unicode code point as an individual token for precise string analysis.
- Two-Way Patching - Implements both forward and reverse delta logic to synchronize objects or restore previous states.
- Custom Equality Definitions - Allows defining custom hashing functions to match objects within arrays by value instead of reference.
- Hashing-Based Matching - Uses custom hashing functions to match array elements and detect moves regardless of index position.
- JSON and Data Schema Tools - Diffs JSON objects and generates patch information.
