An Ember Data adapter that enables offline data storage using Mozilla's localForage library.
Ember Data Localforage Adapter is an Ember.js addon that provides offline data persistence for Ember Data models by integrating Mozilla's localForage as a storage backend. It replaces traditional localStorage adapters with a more robust solution that uses asynchronous storage via IndexedDB or WebSQL where available, while maintaining a simple API. This enables Ember.js applications to work without an internet connection by storing data locally in the browser.
Ember.js developers building web applications that require offline functionality or local data persistence, such as progressive web apps (PWAs) or applications needing to cache data for performance. It is specifically useful for those already using Ember Data who need a cross-browser compatible storage adapter.
Developers choose this adapter over alternatives because it leverages localForage for asynchronous, cross-browser storage with automatic fallbacks (IndexedDB, WebSQL, localStorage), ensuring broader compatibility and better performance than localStorage alone. It also offers configurable caching and namespace support, integrating seamlessly with Ember Data's features like embedded records.
Offline usage for Ember Data, based on localstorage adapter, but now uses Mozilla's localforage as data source

Uses localForage to automatically leverage IndexedDB, WebSQL, or localStorage as fallbacks, ensuring support across all major browsers including older versions like IE 8+ and mobile Safari.
Offers caching options ('model', 'all', 'none') to reduce localForage getItem calls, optimizing read performance by balancing memory usage and access speed.
Allows data isolation through configurable namespaces, enabling multiple independent data stores within a single Ember application for modular design.
Supports Ember Data's embedded records mixin, facilitating the handling of complex object graphs and nested relationships without manual serialization.
Focuses solely on local storage; synchronizing data with a backend server requires additional custom logic, which isn't provided out of the box, limiting its use for online-offline hybrid apps.
Dependent on browser storage APIs like IndexedDB, which have per-origin quotas that may not suffice for data-intensive applications, risking performance degradation or errors.
Tightly coupled with Ember Data versions via semantic versioning alignment, meaning updates or breaking changes in Ember Data might necessitate adapter modifications or cause compatibility issues.
