ember-service-worker-asset-cache

ember-service-worker-asset-cache is a plugin for Ember Service Worker that automatically caches an Ember application's asset files, enabling offline functionality and improved performance. It provides developers with fine-grained control over which assets are cached and how they are managed.

Key Features

• Asset Caching — Caches files from the assets folder by default for offline access
• Flexible Configuration — Allows inclusion and exclusion of specific files using glob patterns
• CDN Support — Configurable CDN URL for assets hosted on external domains
• Manual Asset Inclusion — Supports adding external assets via URLs to the cache
• Cache Versioning — Version-based cache busting to ensure asset updates
• Request Mode Control — Configurable fetch request mode (cors/no-cors) for cross-origin resources
• Lenient Error Handling — Option to prevent single file errors from blocking cache updates

Philosophy

The plugin follows a pragmatic approach to service worker asset caching, providing sensible defaults while offering extensive configuration options to handle diverse deployment scenarios and asset management needs.
