Urql

urql is a GraphQL client and data management tool used to execute GraphQL operations and synchronize data from remote servers within a software application. It functions as a mechanism for fetching, caching, and managing GraphQL data to maintain state across application views.

The project features a pluggable middleware architecture and a normalized GraphQL cache. This allows for the insertion of custom logic into the request and response lifecycle to modify client behavior and the organization of responses by unique identifiers to ensure data consistency.

The client provides capabilities for GraphQL data fetching, including the execution of queries and mutations. It also supports result caching and normalized cache management to reduce redundant network requests.

Features

GraphQL Normalized Caches - Provides a normalized cache that stores GraphQL data by unique identifiers to maintain consistency across views.

Client Query Execution - Handles the execution of GraphQL queries and mutations from the client to a remote server.

State Synchronization - Synchronizes the local application state with remote GraphQL endpoints using queries and mutations.

Normalized Data Caching - Implements a normalization strategy to store remote data in flat structures and prevent duplication.

Pluggable Transport Layers - Decouples the API request mechanism from client logic, allowing interchangeable network transport and cache layers.

Middleware-Based Request Pipelines - Implements a pluggable chain of middleware to intercept and modify GraphQL requests and responses.

GraphQL Client Middleware - Offers a system for inserting custom logic into the GraphQL request and response lifecycle to modify client behavior.

Data Fetching - Facilitates the retrieval, caching, and synchronization of data from GraphQL servers.

GraphQL Clients - Provides a highly customizable GraphQL client for defining and executing queries against remote endpoints.

GraphQL Data Management Libraries - Provides a versatile interface for fetching, caching, and synchronizing GraphQL data from remote servers.

Request Pipelines - Allows developers to insert custom logic into the request-response lifecycle via interchangeable middleware pipelines.

GraphQL Result Caches - Maps specific GraphQL documents and variables to their responses to avoid redundant network requests.

Live Update Subscriptions - Uses an observable-driven subscription model to notify the UI of real-time changes in the cached state.

Client Exchange Plugins - Provides a pluggable architecture to add custom behaviors and specialized features to the GraphQL client.

Exchange Layers - Builds complex client behavior by nesting specialized exchange layers within a recursive execution chain.

State Management - GraphQL client for Preact.

Frontend Framework Integrations - A simple caching GraphQL client for React.
