A React Native library for creating local database models with an event emitter for global state management.
React Native DB Models is a wrapper library built on top of React Native Store that provides an improved database layer for asynchronous transactions in React Native applications. It fixes issues in the underlying store and offers a more functional, developer-friendly API for managing local data, including an event emitter for write operations to help maintain global storage and enable app re-rendering.
React Native developers building mobile applications that require robust local data management with asynchronous operations and event-driven state updates.
Developers choose this library over alternatives because it provides a more reliable and enhanced abstraction over React Native Store, with built-in event emission on write operations to facilitate global state synchronization and UI re-rendering, simplifying local database management in React Native apps.

The DB emitter triggers on all write operations, allowing developers to maintain global storage and automatically re-render the app, as shown in the usage example with DBEvents.on('all', ...).
It fixes issues in React Native Store and provides dedicated methods like get_id and remove_id for easier ID-based access, improving developer experience over the underlying library.
All CRUD methods are asynchronous with callbacks, aligning with React Native's non-blocking UI philosophy, as explicitly stated in the README for methods like get and add.
The library encourages using a central db.js file for model definitions, simplifying database access across the application, as demonstrated in the setup example.
The event emitter only supports an 'all' event for any write operation, which can lead to inefficient re-renders and lacks fine-grained control for specific data changes.
Reliance on callbacks for all async operations can result in callback hell and complicates error handling compared to modern promise-based or async/await patterns.
The README admits that features like update and replace are 'gonna be added soon,' indicating slow development and missing advanced database capabilities.
As a wrapper over React Native Store, it inherits any limitations or bugs of the base library, and fixes or updates may be delayed or dependent on the underlying project's health.
