📱 TypeScript Client SDK with React Hooks

[VAIBHAVSING]

Overview

Generate type-safe TypeScript client SDK from OpenAPI specs and gRPC protos, with React hooks for seamless frontend integration.

🎯 Goals

• Type Safety: Full TypeScript support from API specs
• React Integration: Custom hooks for data fetching and state management
• Auto-Generation: Automated client generation from specs
• Developer Experience: IntelliSense and error checking
• Real-time: WebSocket/gRPC streaming support

📋 Implementation Tasks

Code Generation Setup

• OpenAPI Client Generation

  • Configure openapi-generator for TypeScript
  • Generate REST API client with fetch support
  • Custom templates for better TypeScript support
  • Error handling and response typing

• gRPC Client Generation

  • Generate TypeScript gRPC clients from proto files
  • gRPC-Web support for browser compatibility
  • Streaming support for real-time features
  • Interceptors for authentication and logging

React Hooks Package

// packages/api-client/src/hooks/useEnvironments.ts
export function useEnvironments() {
  const [environments, setEnvironments] = useState<Environment[]>([])
  const [loading, setLoading] = useState(true)
  const [error, setError] = useState<Error | null>(null)
  
  const { data, error: fetchError, mutate } = useSWR(
    '/api/v1/environments',
    apiClient.environments.listEnvironments
  )
  
  const createEnvironment = useCallback(async (request: CreateEnvironmentRequest) => {
    try {
      const environment = await apiClient.environments.createEnvironment(request)
      mutate() // Revalidate cache
      return environment
    } catch (err) {
      throw new APIError(err)
    }
  }, [mutate])
  
  return {
    environments: data?.environments || [],
    error: fetchError,
    createEnvironment,
    refreshEnvironments: mutate
  }
}

Real-time Integration

• Environment Status Streaming

  • gRPC streaming for real-time status updates
  • React hooks for WebSocket connections
  • Automatic reconnection handling
  • State synchronization with server

• Event-driven Updates

  • Server-sent events integration
  • Optimistic updates for better UX
  • Conflict resolution strategies
  • Offline support with retry logic
