SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The skill provides a reliable, client-side persistence layer for user notifications by storing them in localStorage with a fixed retention policy. It ensures notifications survive page reloads, support read/unread states, and are automatically cleaned up when related tasks are deleted.

Core Features & Use Cases

  • Save new notifications with id, timestamp, taskId, message, read state, and priority; the service auto-assigns missing values.
  • Retrieve all notifications or only unread ones, enabling UI badges and analytics.
  • Mark individual or all notifications as read, and delete as needed.
  • Cleanup notifications when a task is deleted to maintain data integrity.
  • Enforce a 50-notification retention limit to manage storage and performance.
  • Use Case: On app startup, load existing notifications and display unread counts.

Quick Start

Call save with a taskId and message to persist a notification in localStorage and have it auto-assigned an id and timestamp.

Frequently Asked Questions about notification-persistence

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

FAQPage Schema
How do I persist notifications in localStorage so they survive page reloads?▼

To persist notifications in localStorage, save new entries with a taskId and message so the service auto-assigns an id and timestamp. This maintains a durable, client-side notification history that survives page reloads.

How does localStorage state management work for tracking unread notification counts?▼

LocalStorage state management for unread counts works by using getUnread to retrieve only unread notifications, enabling UI badges. You can then use markAsRead or markAllAsRead to update the state as users view them.

What is the best way to clean up notifications when a related task is deleted?▼

The best way to clean up notifications when a related task is deleted is using the cleanupTask method. This removes associated entries from localStorage to maintain data integrity and prevent orphaned notification records.

Can I use this localStorage persistence approach for large-scale frontend notification history?▼

You can use this localStorage persistence for frontend notification history, but it enforces a 50-item retention limit to manage storage and performance. This makes it suitable for small to medium-scale client-side state management rather than large datasets.

What are the limitations of storing notification state in browser localStorage?▼

Limitations of storing notification state in browser localStorage include a strict 50-notification retention limit and browser storage constraints. It is a client-side only solution, meaning data is not synced across devices or servers.
