What is IndexedDB?
Turkish: IndexedDB
IndexedDB is a browser database for storing large structured data persistently with indexes and asynchronous access.
What is IndexedDB?
IndexedDB is a local browser database API for storing larger and more structured data. Compared with Web Storage, which stores simple key-value strings, IndexedDB provides object stores, indexes, and transaction behavior.
Data is stored under the same origin and accessed through an asynchronous API. That matters because larger reads and writes should not block the user interface.
How It Works
IndexedDB uses databases, object stores, and indexes. An application can keep product records, form drafts, message history, file metadata, or offline queues in stores. Indexes make it possible to query efficiently by specific fields.
When used with a Service Worker, it becomes a strong foundation for offline experiences and background synchronization. That is why it appears often in PWA applications.
Business Use and Security
IndexedDB is used in field service apps, offline catalogs, draft-saving forms, large preference data, and client-side caches. It does not replace a server database.
Sensitive data needs encryption decisions, timed cleanup, deletion on logout, and XSS protection.
