@epam/uui-db

UUI DB package

This package is a part of EPAM UUI library.

@epam/uui-db is an experimental state-management solution. It maintains immutable relational database on client, provides means to load data from server, update it both from client, and save it to server asynchronously with UI operations.

Features

• relation data model for state, providing a normalized storage for UI state
• data loading from server, with automatic GraphQL response normalization into tables
• synchronous and transactional updates of state from UI
• asynchronous bi-directional state synchronization between UI and server. UI changes in terms of 'patches' are batched and sent to server. Server can also push updates to UI state
• GIT-like branch-rebase approach to handle state concurrency
• tables can be indexed to speed-up queries
• Views to build arbitrary state projections
• subscriptions to subscribe parts of UI to changes in Views
