PouchDB supports multiple storage backends, allowing developers to choose the most suitable storage option based on the target platform and browser compatibility requirements. The supported storage backends in PouchDB include :
IndexedDB :
* IndexedDB is a low-level API for storing large amounts of structured data in the web browser. It is supported by most modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.
* IndexedDB provides a scalable and efficient storage mechanism for PouchDB, allowing applications to store data locally on the user's device.
WebSQL :
* WebSQL is a deprecated database API that provides a SQL-based interface for storing data in the web browser. It was supported by some older versions of web browsers, including Google Chrome, Safari, and Opera, but has been deprecated in favor of IndexedDB.
* PouchDB includes a WebSQL adapter for compatibility with older browsers, but it is not recommended for new applications due to its deprecated status.
LevelDB :
* LevelDB is a fast, lightweight key-value storage library developed by Google. It is used as the default storage backend for Node.js environments and is also supported by some PouchDB adapters for desktop and mobile applications.
* LevelDB provides efficient storage and retrieval of data, making it suitable for applications that require high performance and scalability.
Memory :
* PouchDB includes a memory adapter that allows developers to store data in memory temporarily. This storage backend is useful for testing and development purposes but is not suitable for production environments as data is not persisted between sessions.
Custom Adapters :
* PouchDB also supports custom adapters, allowing developers to create their own storage backends or integrate with third-party storage solutions. Custom adapters can be implemented to support specific use cases or environments that are not covered by the built-in storage backends.
