IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files and blobs. It allows you to create web applications with rich query abilities regardless of network availability, meaning your applications can work both online and offline. IndexedDB is a NoSQL database, which is integrated into the browser, and it supports transactions for reliability and maintains high performance through asynchronous APIs that do not block the user interface[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].
IndexedDB operates on a same-origin policy, which restricts the data to the domain that created it, enhancing security. It is more powerful than simple storage solutions like localStorage, as it provides considerable storage capacity without the limitations typically associated with web storage. IndexedDB supports storing a variety of data types, from simple strings and numbers to complex objects and files, and it uses indexes to enable high-performance searches of this data[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].
This API is particularly useful for applications that require large amounts of data to be stored on the client side, for applications that ...
