Clearing all sessionStorage data is crucial for logout functionality, session resets, and complete cleanup of temporary browser storage.
As the creator of CoreUI with extensive JavaScript experience since 2000, I’ve implemented sessionStorage clearing in countless production applications for user logout and session management.
The most effective approach uses the clear() method to remove all stored items at once.
This method provides comprehensive cleanup while being more efficient than removing items individually.
Use sessionStorage.clear() to remove all items from session storage instantly.
sessionStorage.clear()
This code removes all key-value pairs stored in sessionStorage for the current origin, effectively resetting the session storage to an empty state. Unlike removeItem() which targets specific keys, clear() wipes everything stored in sessionStorage. This is particularly useful for logout functions, session timeouts, or when you need to completely reset temporary application state.
Best Practice Note:
This is the session cleanup method we use in CoreUI authentication workflows for complete session data reset.
Use clear() for logout scenarios and removeItem() for selective cleanup to maintain optimal storage management practices.
