version-and-minimize-localstorage-data

What problem does it solve?

This Skill helps prevent schema conflicts and accidental storage of sensitive data in localStorage by adding version prefixes to keys and storing only necessary fields.

Core Features & Use Cases

• Versioning: Automatically adds a version prefix (e.g., userConfig:v2) to localStorage keys, enabling smooth schema evolution and migration.
• Data Minimization: Allows storing only essential fields from larger objects (like server responses), reducing storage footprint and enhancing security by excluding sensitive information.
• Error Handling: Provides robust try-catch blocks for localStorage operations, gracefully handling scenarios like incognito mode, quota limits, or disabled storage.
• Use Case: When updating user preferences, ensure that only the theme and language are saved, not the entire user object which might contain PII.

Quick Start

Use the version-and-minimize-localstorage-data skill to save a user's theme and language preferences to localStorage with versioning.
