Questions & Answers

Q: What is GraphQL?

GraphQL is a query language that allows front-end applications to communicate with back-end applications by requesting data in a consistent and efficient manner, regardless of the underlying programming language or data source.

Q: How does GraphQL handle data fetching?

GraphQL functions as a runtime that executes queries. The server defines types for the available data and resolvers to fetch the data from databases or other sources. It returns only the requested fields in the JSON payload.

Q: How does GraphQL differ from REST APIs?

GraphQL replaces the need for multiple URL endpoints in REST APIs with a single entry point. Instead of making multiple requests for each piece of data, GraphQL allows the front-end to request all the required data in a single query. It simplifies and optimizes the data fetching process.

Q: What are the advantages and disadvantages of using GraphQL?

The advantages of GraphQL include its flexibility, efficient data fetching, and strong typing, which allows for excellent tooling. However, it can be more complex to set up compared to REST APIs, and the benefits may not be significant for small or simple projects.

Summary & Key Takeaways

• GraphQL is a query language that enables front-end applications to communicate with back-end applications by requesting data in a consistent way.

• The GraphQL server defines types for the available data and resolvers to fetch the data from various sources.

• GraphQL simplifies the process of fetching data by providing a single entry point for the API and returning only the requested fields.
