Design Microservices Architecture with Patterns and Principles - REST Versus GraphQL APIs

The video discusses the differences between GraphQL and REST APIs. REST is a popular and scalable API design but suffers from inflexibility and issues like overfetching and underfetching. GraphQL offers more flexibility and efficiency, solving some of REST's shortcomings, but it is more complex and has its own challenges, such as error reporting and caching. The video compares both API styles, highlighting their strengths and weaknesses.

What is one of the main reasons GraphQL was developed?

• To make APIs more complex

• To reduce the popularity of REST

• To provide a more flexible and efficient API solution

• To replace REST entirely

Which of the following is an advantage of REST APIs?

• Complex error reporting

• Protocol agnostic

• Solves underfetching problems

• Built-in caching

What is a major drawback of GraphQL?

• Lack of scalability

• Overfetching issues

• Inflexibility

• Complexity and caching problems

How does GraphQL address the issue of overfetching and underfetching?

• By using a flexible schema and type system

• By being more popular

• By simplifying error reporting

• By increasing the number of API calls

What is a key difference in how GraphQL and REST handle data transfer?

• REST solves underfetching problems

• GraphQL uses HTTP while REST does not

• GraphQL can fetch hierarchical data at once

• REST is protocol agnostic
