ObjectBox vs Realm React Native: What are the differences?

Introduction

In this article, we will explore the key differences between ObjectBox and Realm React Native. Both ObjectBox and Realm React Native are database solutions that are utilized in React Native applications. While they serve a similar purpose, there are distinct differences that set them apart from each other. Now, let's delve into the key differences between ObjectBox and Realm React Native.

1. Performance: ObjectBox is known for its exceptional performance as it utilizes a highly optimized native database engine. It boasts efficient data storage and retrieval mechanisms, resulting in faster read and write operations. On the other hand, Realm React Native also offers good performance, but it doesn't match the level of optimization and speed provided by ObjectBox.

2. Data Synchronization: ObjectBox primarily focuses on providing local database functionalities and doesn't natively support data synchronization across devices or platforms. It is ideal for scenarios where data synchronization is not a requirement. Meanwhile, Realm React Native offers built-in support for data synchronization and provides real-time data updates across devices, making it suitable for applications requiring real-time collaboration or multi-device synchronization.

3. Cross-Platform Support: ObjectBox supports multiple platforms, including Android, iOS, macOS, Linux, WebAssembly, and more. It provides a consistent API across various platforms, allowing developers to seamlessly integrate ObjectBox into their projects. On the other hand, Realm React Native primarily focuses on supporting React Native applications and offers limited support for other platforms. It is designed to provide an easy-to-use interface specifically for React Native developers.

4. Schema Evolution: ObjectBox provides robust schema evolution capabilities, allowing smooth database schema updates without the need for manual migrations. Developers can easily modify their object schema and handle changes transparently. In contrast, Realm React Native also offers schema evolution, but it requires manual migrations for handling schema changes, which can be more tedious and error-prone in comparison.

5. Query Capabilities: ObjectBox leverages a Query Language (ObjectBox Query) that offers a wide range of querying capabilities, including powerful filtering, sorting, and aggregation functionalities. It allows developers to write complex queries with ease and efficiency. On the other hand, Realm React Native utilizes a declarative query language and provides a simplified querying API that might be more suitable for simpler query scenarios.

6. Community and Ecosystem: ObjectBox has a smaller but growing community and ecosystem compared to Realm React Native, which has a larger and more established community. Realm React Native benefits from a more extensive community support, a broader range of available resources, and a larger developer base. This can be particularly advantageous for developers seeking community-driven solutions, documentation, and third-party integrations.

In summary, ObjectBox provides exceptional performance, supports multiple platforms, and offers robust schema evolution and flexible querying capabilities. It is an ideal choice for applications where performance and cross-platform compatibility are crucial but without data synchronization requirements. On the other hand, Realm React Native focuses on providing seamless data synchronization across devices and platforms, making it suitable for real-time collaboration scenarios or applications requiring multi-device synchronization.
