Building Scalable APIs with GraphQL

Why GraphQL Over REST?

GraphQL addresses many of the limitations of traditional REST APIs by allowing clients to request exactly the data they need. This eliminates over-fetching and under-fetching issues common with REST endpoints.

Key Advantages

• Single Endpoint: One URL handles all data fetching
• Precise Data Fetching: Clients specify exactly what they need
• Strong Typing: Schema provides clear contracts between client and server
• Real-time Updates: Subscriptions enable live data

Getting Started with GraphQL

Building a GraphQL API involves defining a schema, creating resolvers, and setting up your GraphQL server. Popular implementations include Apollo Server, GraphQL Yoga, and Graphene for Python.

GraphQL represents the future of API design, offering flexibility and efficiency that traditional REST APIs can't match.
