Single endpoint architecture in GraphQL - Cheat Sheet & Quick Revision

Recall & Review

What is Single Endpoint Architecture in GraphQL?

It means using one URL endpoint to handle all client requests instead of multiple URLs. This single endpoint processes queries and returns exactly the data requested.

beginner

Why does GraphQL use a single endpoint instead of multiple endpoints like REST?

Because GraphQL lets clients specify exactly what data they want in one request, so one endpoint can handle many types of queries and mutations efficiently.

How does a single endpoint improve client-server communication?

It reduces the number of requests clients make, avoids over-fetching or under-fetching data, and simplifies API management by centralizing data access.

What role does the GraphQL schema play in single endpoint architecture?

The schema defines all possible queries and mutations the single endpoint can handle, guiding how data is fetched and shaped for clients.

advanced

Can a single endpoint architecture handle complex data requirements? How?

Yes, by allowing clients to request nested and related data in one query, the single endpoint can return complex, tailored responses efficiently.

What does the single endpoint in GraphQL typically represent?

A One URL that handles all queries and mutations

B Multiple URLs for different data types

C A database connection string

D A client-side library

GraphQL uses one URL endpoint to process all client requests, unlike REST which uses multiple URLs.

Which of the following is a benefit of single endpoint architecture?

A It requires multiple endpoints to manage

B Clients must make multiple requests for different data

C It increases over-fetching of data

D Clients can request only the data they need

Single endpoint lets clients specify exactly what data they want, reducing unnecessary data transfer.

In GraphQL, what defines the structure of data available through the single endpoint?

A Client-side code

B REST API documentation

C GraphQL schema

D Database tables

The GraphQL schema defines all queries and mutations the endpoint can handle.

How does single endpoint architecture affect API versioning?

A It requires a new endpoint for each version

B It simplifies versioning by evolving the schema without changing the endpoint URL

C It prevents any changes to the API

D It duplicates endpoints for backward compatibility

GraphQL allows schema evolution at the single endpoint, avoiding multiple versioned URLs.

Which statement about single endpoint architecture is FALSE?

A It requires clients to know multiple URLs

B It can handle nested and related data in one request

C It reduces the number of network requests

D It centralizes data fetching logic

Clients only need to know one URL in single endpoint architecture, not multiple.

Explain how single endpoint architecture works in GraphQL and why it is beneficial compared to multiple endpoints.

Think about how clients ask for data and how the server responds.

Describe the role of the GraphQL schema in supporting single endpoint architecture.

Consider what tells the server what data can be requested.
