GraphQL & Advanced Protocols Deep Dive

Overview

GraphQL vs REST trade-offs + gRPC alternatives.

Core Concepts

REST: - Resource-oriented - Fixed response shapes - Over/under-fetching common GraphQL: - Query language - Client specifies fields - Reduces bandwidth - Learning curve gRPC: - Binary protocol (faster) - Protocol Buffers schemas - Streaming support - Less browser-friendly

Code Examples

// Apollo Kotlin for GraphQL
val apolloClient = ApolloClient.Builder()
    .serverUrl("https://api.example.com/graphql")
    .build()
// Query
val query = GetUserQuery(id = "123")
val response = apolloClient.query(query).execute()

Senior-Level Insights

• GraphQL best for complex queries
• gRPC for services/microservices
• REST for simple CRUD
