SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

HR-IMS frontend often needs durable, typed, client-side storage to preserve user preferences and transient session data across reloads and tabs. This Skill provides type-safe hooks and utilities to manage localStorage and sessionStorage with JSON serialization, expiration, and safe fallbacks.

Core Features & Use Cases

  • Type-safe localStorage and sessionStorage hooks with JSON serialization
  • Expiration support and cross-tab synchronization
  • Storage utilities and migrations to evolve storage schemas safely
  • Use cases include persisting user preferences (theme, language), form drafts, and lightweight session data across the app

Quick Start

Install and start using the hooks in your React components to persist user preferences and session data.

Frequently Asked Questions about local-storage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I persist user preferences in localStorage with TypeScript?

Persist user preferences in localStorage using type-safe hooks that handle JSON serialization automatically. These hooks provide typed client-side storage, ensuring preference data survives page reloads while maintaining strict TypeScript type checking.

Can I synchronize localStorage changes across multiple browser tabs?

Yes, localStorage changes can be synchronized across multiple browser tabs. The hooks support cross-tab updates, ensuring that data mutations in one tab automatically propagate to other open tabs sharing the same storage keys.

How do I set expiration times for sessionStorage entries?

Set expiration times for sessionStorage entries using built-in expiration helpers. These utilities automatically manage time-to-live values, ensuring transient session data and lightweight form drafts are purged when their lifespan expires.

What is the best way to handle storage schema migrations in a frontend app?

Handle storage schema migrations using dedicated migration utilities that evolve stored JSON schemas safely. These tools ensure forward compatibility, allowing your application to update storage structures without losing previously persisted user data.

Why does my localStorage hook return null on first render?

A localStorage hook returns null on first render because the browser's storage is accessed client-side after initial mount. The hook includes safe fallbacks, initializing with default values before reading and deserializing the persisted JSON data.

Do I need React to use these local-storage and session-storage hooks?

Yes, React is required to use the useLocalStorage and useSessionStorage hooks. These hooks are designed for React components to provide a compact API surface for managing typed, client-side persistence with JSON serialization.
