Browsers have several types of data storage:
-
Cookies — small pieces of data sent to the server with each request. Used for sessions, authentication. Limited in size (~4KB), have an expiration date.
-
LocalStorage — key-value storage, stores data without an expiration date, accessible only on the client side. Usually around 5-10 MB in size. Data persists between sessions.
-
SessionStorage — similar to LocalStorage, but data only lives within a single session (while the browser tab/window is open).
-
IndexedDB — a more powerful storage, a database in the browser, supports storing large amounts of structured data, transactions, indexes. Used for offline applications.
-
Cache Storage — used by service workers to cache resources (HTML, JS, CSS) for offline access.
The choice depends on the task: for simple settings — LocalStorage, for sessions — SessionStorage or Cookies, for large and complex data — IndexedDB.
