typeorm/typeorm
36,540在 GitHub 上查看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

Expensify/App
4,725在 GitHub 上查看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

TypeScript - doctrine-extensions/doctrineextensions
doctrine-extensions/DoctrineExtensions
4,143在 GitHub 上查看DoctrineExtensions 是一套为 Doctrine ORM 设计的可重用行为扩展，旨在自动化常见的实体任务。它提供了一个系统，用于跟踪数据库实体的历史变更、实现软删除工作流、管理层级数据的嵌套集树结构，以及根据语言区域存储翻译后的字段值。 该项目提供专门的实体审计工具（记录修改后的值和时间戳）以及用于多语言内容管理的翻译框架。它还包含一个用于将实体组织为父子关系的树管理器，以及一种在不物理删除记录的情况下将其标记为已删除的机制。 其他功能涵盖了时间戳和所有权自动元数据跟踪、搜索引擎友好的 URL 别名生成，以及实体序列管理。该工具包还处理数据字段内的文件上传处理。

lazychaser/laravel-nestedset
3,801在 GitHub 上查看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
