• Use Cases:

  SQLite is suitable for small to medium-sized databases in mobile applications, such as storing user preferences, settings, or caching data.

• Code Examples:

  Integration with SQLite in React Native typically involves using libraries like react-native-sqlite-storage. Developers can create tables, perform CRUD operations, and handle transactions using SQL queries.

• Performance Considerations:

  SQLite is known for its speed and efficiency, making it a preferred choice for apps requiring fast data access.
  

2. Realm

• Features:

  Realm is an object-oriented, cross-platform database that offers real-time synchronization. It’s known for its speed and efficiency, thanks to its C++ core.

• Use Cases:

  Realm is suitable for applications requiring real-time data updates, such as chat apps, collaborative tools, or applications with frequent data changes.

• Code Examples:

  Realm provides a straightforward API for managing data as objects. Developers can define data models and relationships directly in code.

• Performance Considerations:

  Realm’s architecture and real-time synchronization make it a powerful choice for apps where data consistency and performance are crucial.
  

3. AsyncStorage

• Features:

  AsyncStorage is a simple key-value pair storage system included with React Native. It’s synchronous and can store data in a serialized format.

• Use Cases:

  AsyncStorage is ideal for storing small amounts of data like authentication tokens, user settings, or app configuration.

• Code Examples:

  While AsyncStorage is straightforward to use with React Native, developers can set, get, and remove key-value pairs using asynchronous methods.

• Performance Considerations:

  While AsyncStorage is easy to use, it may not be suitable for complex data structures or larger datasets due to its synchronous nature.
  

4. WatermelonDB

• Features:

  WatermelonDB is an offline-first database for React Native that combines the ease of a JSON-based data store with the power of a relational database.

• Use Cases:

  WatermelonDB is excellent for applications requiring offline support and complex data relationships, such as task management or note-taking apps.

• Code Examples:

  Developers can define data models and relationships, perform CRUD operations, and work with data in a more intuitive way compared to traditional SQL databases.

• Performance Considerations:

  WatermelonDB is optimized for offline use, making it a strong choice for apps that need to work seamlessly both online and offline.
  

5. PouchDB

• Features:

  PouchDB is a NoSQL database that stores data in JSON format and is designed to work well with CouchDB. It offers seamless replication and offline support.

• Use Cases:

  PouchDB is suitable for apps that need to synchronize data between devices or with a central server, making it ideal for collaborative or distributed applications.

• Code Examples:

  PouchDB provides an easy-to-use JavaScript API for CRUD operations and synchronization.

• Performance Considerations:

  PouchDB’s performance shines when handling synchronization between devices or servers, making it a strong choice for multi-device applications.
  

6. LokiJS

• Features:

  LokiJS is an in-memory database with a simple API that stores data as objects. It’s suitable for applications that require in-memory data manipulation.

• Use Cases:

  LokiJS is often used for client-side caching or data transformations, such as filtering and sorting in memory before rendering.

• Code Examples:

  Developers can create collections, insert and query data, and perform in-memory operations with ease.

• Performance Considerations:

  LokiJS is lightning-fast for in-memory operations but may not be suitable for apps with large datasets or complex querying requirements.
  

7. Firebase Realtime Database

• Features:

  Firebase Realtime Database is a cloud-hosted NoSQL database that offers real-time synchronization. It’s suitable for building collaborative and real-time applications.
