IndexedDB vs RxDB: What are the differences?
IndexedDB vs RxDB
IndexedDB and RxDB are both database technologies that can be used in web applications. However, they have several key differences that set them apart.
-
Data Querying and Manipulation: IndexedDB is a low-level API that allows developers to directly query and manipulate data stored in the database. It provides powerful features like indexes and cursors for efficient data access. On the other hand, RxDB is built on top of IndexedDB and provides a reactive interface for data querying and manipulation. It leverages the power of Observables to provide a more convenient and efficient way of working with data.
-
Synchronization and Offline Support: IndexedDB does not natively support synchronization or offline support. Developers need to implement their own mechanisms for syncing data between clients or providing offline functionality. RxDB, on the other hand, includes built-in support for data synchronization and offline capabilities. It provides conflict resolution mechanisms and automatic syncing between clients, making it more suitable for applications that require offline functionality.
-
Event Handling: IndexedDB uses events and callbacks for handling database operations and changes in data. Developers need to manually handle these events to update their application's UI or perform other actions. RxDB, on the other hand, provides a more declarative approach to event handling. It allows developers to use Observables to easily react to changes in data or database operations, simplifying the handling of events.
-
Schema Management: IndexedDB does not enforce any schema for data stored in the database. This means that the structure and format of the data can vary between different records. RxDB, on the other hand, provides schema management capabilities. Developers can define schemas for their data, specifying the structure and validation rules. RxDB enforces these schemas, ensuring data consistency and allowing for easier data handling.
-
Language Support: IndexedDB is a web standard API and is supported by most modern browsers. It can be used with JavaScript or any other web programming language. RxDB, on the other hand, is a library built specifically for JavaScript and is not supported natively by all browsers. Developers need to include the RxDB library in their application to use its features.
-
Community and Ecosystem: IndexedDB has been around for a longer time and has a larger community and ecosystem. There are various tools, libraries, and resources available for working with IndexedDB, making it easier to find support and solutions to common problems. RxDB, on the other hand, is a relatively newer technology and has a smaller community and ecosystem. While it is growing in popularity, the availability of resources and community support may be more limited compared to IndexedDB.
In summary, IndexedDB is a low-level API for data storage and manipulation, while RxDB provides a higher-level and more convenient interface for working with data. RxDB includes built-in support for synchronization and offline capabilities, as well as schema management and declarative event handling. However, it is a JavaScript-specific library and has a smaller community and ecosystem compared to IndexedDB.
