TypeORM is an object-relational mapper for TypeScript and JavaScript that bridges the gap between object-oriented application code and relational database tables. It provides a comprehensive data persistence layer that allows developers to define database entities using class decorators or configuration objects, enabling seamless interaction with data through object-oriented patterns. The project distinguishes itself through a flexible architecture that supports both the data mapper and repository patterns, alongside a fluent query builder that translates high-level method calls into platform
Stores tree structures using nested sets to achieve high read efficiency for hierarchies.
Expensify App is a cross-platform collaborative expense management platform that combines receipt capture, expense tracking, and shared bill splitting for groups and teams. Designed as an offline-first application, it applies user actions optimistically to local state and queues them for server synchronization, with automatic rollback if the server rejects an operation. The application is built on a reactive client-side key-value store called Onyx that broadcasts changes to subscribed components and persists data to disk for offline access. Its cross-platform TypeScript and React codebase com
Structures expenses, messages, and metadata under report objects in a nested document hierarchy.
DoctrineExtensions es una colección de extensiones de comportamiento reutilizables para Doctrine ORM diseñadas para automatizar tareas comunes de entidades. Proporciona un sistema para rastrear cambios históricos en entidades de base de datos, implementar flujos de trabajo de eliminación lógica (soft deletion), gestionar estructuras de árbol de conjuntos anidados para datos jerárquicos y almacenar valores de campos traducidos basados en locales de idioma. El proyecto se distingue por proporcionar herramientas especializadas para la auditoría de entidades, que registra valores modificados y marcas de tiempo, y un framework de traducción para la gestión de contenido multilingüe. También incluye un gestor de árboles para organizar entidades en relaciones padre e hijo y un mecanismo para marcar registros como eliminados sin eliminarlos físicamente de la base de datos. Las capacidades adicionales cubren el seguimiento de metadatos automatizado para marcas de tiempo y propiedad del usuario, la generación de slugs de URL amigables para motores de búsqueda y la gestión de secuencias de entidades. El toolkit también maneja el procesamiento de cargas de archivos dentro de campos de datos.
Implements the nested set pattern using left and right integer boundaries to manage hierarchical tree structures.
This library provides a framework for managing hierarchical data structures within relational databases using the nested set model. It integrates directly with the Laravel Eloquent object-relational mapping layer, allowing developers to store, query, and manipulate complex parent-child relationships within standard database tables. The package distinguishes itself by implementing boundary-based indexing to represent tree depth and node containment. This approach enables the retrieval of entire branches or specific ancestors, descendants, and siblings through optimized database queries rather
