Why Store?

Quickstart

Overview

Store foundations

The core component of the Store library, managing data flow between network, memory cache, and local storage in your app.

Store

Designed to handle not only data retrieval but also data mutations. Manages the complexities associated with data synchronization between local and remote sources, conflict resolution, and offline support.

Mutable Store

Single authoritative local data source, ensuring data consistency and enabling offline support.

Source of Truth

Responsible for retrieving data from remote sources, such as web services or APIs. It defines how fresh data is fetched when the the Store doesn't have the required information or when the data needs to be refreshed. 

Fetcher

Responsible for synchronizing local data mutations with remote data sources.

Updater

Designed to track local data changes that haven't been successfully synchronized with the remote data source. It plays a crucial role in conflict resolution, especially in applications that support offline operations or have intermittent network connectivity.

Bookkeeper

Allows you to define custom logic to determine whether your local data is still valid or if it needs to be refreshed from the remote source using the Fetcher.

Validator

Handles the transformation of data between network, local storage, and domain models.
