useSessionStorage Hook Keeps React Form State Alive Across Reloads Without Tab Bleed
A common problem in React checkout flows is that useState resets completely on page reload or third-party redirects, causing users to lose filled form data mid-flow. While localStorage is a popular fix, it persists data across all tabs and beyond the current session, creating unintended state sharing. sessionStorage solves this by scoping data to a single browser tab, surviving reloads and redirects but clearing when the tab is closed. The useSessionStorage hook from @reactuses/core offers a drop-in useState-style API that reads from and writes to sessionStorage automatically. Developers should note edge cases such as window.open copying sessionStorage as a one-time snapshot, and browsers that restore closed tabs also restoring their sessionStorage.
