Features

• Application State Management - Provides a reactive system for managing and synchronizing application-wide state using relational tables or key-value pairs.
• Local-First Storage Engines - Provides a local-first sync engine that ensures deterministic data convergence using CRDTs and logical clocks.
• Local-First Synchronization - Implements a local-first architecture that prioritizes offline data access with conflict-free remote synchronization.
• Data Change Listeners - Registers callbacks that trigger automatically when specific values, tables, or cells are modified.
• Local-First Data Persistence - Uses Conflict-free Replicated Data Types to ensure local-first reconciliation and persistence.
• Client-Side Persistence - Manages data storage directly on user devices and within browser environments to maintain state across sessions.
• Tabular Row Storage - Organizes data into structured rows and columns using primary keys for tabular storage.
• Deterministic State Merging - Ensures deterministic data convergence across instances using CRDT logic and hybrid logical clocks.
• In-Memory Databases - Functions as a lightweight in-memory database supporting relational structures, querying, and indexing for low-latency performance.
• Key-Value Stores - Provides a lightweight key-value storage system for persisting application state.
• Relational Data Modeling - Organizes data into a hierarchy of tables and rows using foreign keys to model complex entity relationships.
• Mutable State Tracking - Tracks changes to data and triggers listeners on specific entities to update the UI.
• Reactive Data Stores - Initializes a central reactive state container to manage and synchronize application data.
• Deterministic State Convergence - Uses hybrid logical clocks and last-write-wins logic to ensure deterministic state convergence across distributed data stores.
• CRDT State Synchronization Engines - Provides a synchronization engine using conflict-free replicated data types to maintain consistency across distributed clients.
• Sync Conflict Resolution - Implements processes for detecting and resolving version mismatches and conflicts between synchronized datasets.
• Fine-Grained Reactivity - Tracks data dependencies at the cell, row, and table level to trigger high-performance, fine-grained UI updates.
• Client-Side State Management - Provides a comprehensive mechanism for managing application state within the browser and persisting it to local or remote storage.
• Reactive State Management - Uses a reactive store to automatically update the user interface when the underlying application state changes.
• Automerge Synchronizations - Provides synchronization between the local data store and Automerge documents to maintain consistent state across clients.
• Client-Server State Synchronization - Synchronizes local client state with a remote PartyKit server to maintain coherence across distributed environments.
• Atomic Transaction Execution - Groups multiple data changes into atomic transactions to ensure consistent application of state mutations.
• Data Persistence - Automatically synchronizes the in-memory data store with a persistence layer by listening for state changes.
• Data Schema Definitions - Provides declarative systems for defining tabular data structures and enforcing value types.
• Database Indexing - Creates indexes that allow rapid retrieval of matching row objects within large data tables.
• SQL-like Queries - Performs fast lookups via indexes and executes SQL-like operations including joins and filters.
• General State Persistence - Saves data to a storage medium so that state is maintained across sessions and page reloads.
• Durable Object Persistence - Saves a data store to Cloudflare Durable Objects using JSON serialization or fragmented SQL rows.
• Relational Join Engines - Combines information from multiple tables by linking related records through foreign keys.
• Relationship Management - Defines and tracks relationships between different entities within the data store.
• Schema Validation Libraries - Provides a schema validation library that converts Zod, Yup, and TypeBox definitions into type-safe store structures.
• SQLite or PostgreSQL Storage - Persists application state to SQLite or PostgreSQL databases using JSON blobs or tabular mapping.
• Pluggable State Backends - Offers a pluggable architecture to switch between different storage backends like IndexedDB, SQLite, or cloud objects.
• Browser Storage Persistence - Saves and loads application data using browser-native storage like session storage, local storage, or OPFS.
• Third-Party Sync Integrations - Integrates the local store with external synchronization platforms and CRDT libraries to leverage cloud infrastructure.
• Store API Type Safety - Infers API types from defined schemas to provide type constraints for store methods and listeners.
• State Storage Implementations - Allows definition of custom logic to fetch, write, and monitor changes in external storage backends.
• Multi-Transport Real-time Layers - Uses multi-transport layers including WebSockets and BroadcastChannels to exchange real-time state updates.
• Atomic Transaction Grouping - Bundles multiple state mutations into a single atomic operation to prevent intermediate listeners from firing.
• Operation Interceptors - Provides operation interceptors that run before data writes to validate, modify, or block mutations.
• Server-Side Sources of Truth - Establishes a server-side store as the authoritative source of truth that persists data and synchronizes with clients.
• Schema-Driven Type Inference - Automatically derives static TypeScript type definitions from internal runtime store schemas for type-safe operations.
• Schema Type Inference - Generates TypeScript type definitions based on active data schemas for improved type safety.
• Write Interception Middleware - Registers hooks that run before data is written to intercept, modify, or block updates based on validation rules.
• Bidirectional Data-Binding - Synchronizes interface components with the data store by automatically updating views and writing user input back.
• SolidJS Bindings - Connects the reactive data store to SolidJS components using fine-grained accessors for automatic updates.
• Declarative UI Components - Provides pre-built declarative components to display specific parts of the data store.
• Svelte Bindings - Creates reactive objects that automatically update Svelte user interface elements when the store changes.
• Real-Time Collaborative Editing - Synchronizes data changes across multiple users instantly for simultaneous editing of shared interfaces.
• Update Batching - Groups multiple store modifications into a single transaction to prevent redundant listener triggers.
• Undo-Redo History - Tracks state changes over time to allow users to revert to previous versions or re-apply changes.
• React State Bindings - Provides specialized bindings that connect the reactive data store to React UI components.
• Yjs Document Synchronizations - Persists application state to Yjs documents to enable real-time collaborative synchronization and shared data.
• Miscellaneous Tools - Reactive data store for local-first applications.

TinyBase 是一个响应式数据存储和内存关系数据库，专为客户端状态持久化而设计。它作为一个本地优先（local-first）的同步引擎，使用无冲突复制数据类型（CRDT）和逻辑时钟合并分布式状态，以确保确定性的数据收敛。
