cache-storage-api-calls

What problem does it solve?

This Skill addresses the performance bottleneck of synchronous, repeated access to browser storage APIs like localStorage, sessionStorage, and document.cookie by implementing in-memory caching.

Core Features & Use Cases

• In-memory caching: Utilizes a Map to store frequently accessed storage values, reducing direct DOM/storage reads.
• Synchronized updates: Ensures the cache is updated when storage is modified.
• Cache invalidation: Implements strategies to clear the cache based on browser events like storage and visibilitychange for external changes.
• Use Case: Improve the responsiveness of web applications by caching theme settings or user preferences retrieved from localStorage.

Quick Start

Implement in-memory caching for localStorage reads and writes to optimize performance.
