Design Microservices Architecture with Patterns and Principles - Graph: QLA Query Language for APIs

GraphQL is a query language for APIs developed by Facebook, released in 2015. It allows clients to specify the data structure they need, providing predictable results and reducing network calls. GraphQL supports API evolution without versioning, enabling continuous access to new features. It uses HTTP POST for data creation, similar to REST APIs but more efficient in handling multiple resources in a single request.

What is the primary function of GraphQL?

• To replace all existing databases

• To create static web pages

• To serve as a query and manipulation language for APIs

• To provide a new programming language

What does GraphQL provide to clients regarding data structure?

• A complex data structure

• A random data structure

• A flexible syntax to describe data requirements

• A fixed data structure

How does GraphQL help in reducing network calls?

• By compressing data before sending

• By using a faster internet connection

• By caching all data on the client side

• By allowing access to many resources in a single request

Which method does GraphQL use for creating data?

• HTTP PUT

• HTTP GET

• HTTP DELETE

• HTTP POST

What is a key advantage of using GraphQL over REST APIs?

• GraphQL is easier to learn

• GraphQL can evolve without requiring versions

• GraphQL is more secure

• GraphQL requires less coding
