FraiseQL Client Implementation Guides

Status: ✅ Production Ready Audience: Frontend developers, mobile developers Last Updated: 2026-02-05

Complete guides for querying FraiseQL servers from different client frameworks and platforms.

Client Frameworks

FraiseQL is a GraphQL backend, so any GraphQL-compatible client library can query it. This section provides language-specific guides and best practices.

Web Clients

React with Apollo Client — Web applications using React

  • Apollo Client setup and configuration
  • Query and mutation patterns with hooks
  • Cache management strategies
  • Real-time subscriptions with WebSockets
  • Error handling and retries
  • Performance optimization

Vue 3 with Apollo Client — Vue 3 Composition API integration

  • Apollo Client for Vue setup
  • Composition API query hooks
  • Reactive state management
  • Subscription handling in Vue components
  • TypeScript support
  • Server-side rendering (Nuxt)

Mobile Clients

Flutter with GraphQL Client — Flutter mobile applications

  • GraphQL package installation and configuration
  • Query and mutation patterns
  • Local caching with HiveDB
  • Real-time subscriptions
  • Error handling for mobile networks
  • State management (Provider, Riverpod)
  • iOS and Android deployment

React Native with Apollo Client — React Native mobile applications

  • Apollo Client setup for React Native
  • Query and mutation patterns
  • AsyncStorage for persistence
  • WebSocket subscriptions
  • Android and iOS specific considerations
  • Offline support strategies

Backend & CLI Clients

Node.js Runtime Client — Backend server-to-server queries

  • FraiseQL Node.js client library
  • Query execution from backend services
  • Batch query processing
  • Server-side authentication
  • Error handling and retries
  • Performance tuning

Common Patterns

State Management

  • React: Context API vs Redux vs Zustand + Apollo caching
  • Vue: Pinia + Apollo Client composables
  • Flutter: Provider, Riverpod, GetX
  • React Native: Redux with Apollo Client

Error Handling

All clients should implement:

  • Authentication errors (401)
  • Authorization errors (403)
  • Validation errors (422)
  • Network errors (timeout, offline)
  • Server errors (500)
  • GraphQL errors in response

Caching Strategies

  • InMemoryCache (Apollo) vs server-side caching
  • Cache invalidation on mutations
  • Partial query caching
  • Refetch policies

Subscriptions

  • WebSocket upgrade requirements
  • Connection lifecycle management
  • Error recovery
  • Memory cleanup on unsubscribe

Performance Optimization

Client-Side

  • Query memoization and deduplication
  • Lazy loading with @lazy directive
  • Pagination for large result sets
  • Prefetching for anticipated queries
  • Connection pooling (backend clients)

Network

  • Persisted queries to reduce payload size
  • gzip compression
  • HTTP/2 multiplexing (when available)
  • Query batching for multiple operations

Caching

  • Cache-first strategies for static data
  • Cache-and-network for semi-static data
  • Network-only for frequently changing data

Testing Client Code

Each guide includes testing patterns for:

Unit Tests

  • Query building and validation
  • Error handling
  • Cache state management

Integration Tests

  • Mock FraiseQL server responses
  • Subscription lifecycle
  • Error scenarios

E2E Tests

  • Full user workflows
  • Real backend connectivity
  • Performance under load
