Vyuh Cache ​

vyuh_cache on pub.dev

The vyuh_cache package provides a flexible caching solution for Vyuh Framework Apps, offering time-based caching with pluggable storage backends to reduce API calls and boost performance.

Overview ​

Caching is essential for responsive applications. This package provides a general-purpose caching layer that can be used throughout your Vyuh application to cache API responses, computed values, and other data that benefits from local storage.

Key Features ​

  • Time-based expiration -- Configure cache duration for automatic invalidation
  • Pluggable storage backends -- Swap between different storage implementations
  • Key-based caching -- Store and retrieve values using string keys
  • Hashing support -- Built-in cryptographic hashing for cache key generation
  • Pure Dart -- No Flutter dependency, usable in any Dart project

Dependencies ​

  • crypto -- For cache key hashing
  • json_annotation -- For serialization support

Usage ​

dart
import 'package:vyuh_cache/vyuh_cache.dart';

// Create a cache instance with a time-based expiration
final cache = VyuhCache(
  duration: Duration(minutes: 5),
);

// Store a value
await cache.put('my-key', myData);

// Retrieve a value
final data = await cache.get('my-key');

// Check if a value exists and is not expired
final exists = await cache.has('my-key');

Integration with Content Provider ​

The cache is used internally by the Sanity content provider (vyuh_plugin_content_provider_sanity) to cache CMS responses and reduce network calls. You can configure the cache duration when setting up the content provider:

dart
SanityContentProvider.withConfig(
  config: SanityConfig(...),
  cacheDuration: const Duration(seconds: 5),
)
