Understanding GraphQL fundamentals in NestJS
In this chapter, we’ll embark on a journey to understand GraphQL, a revolutionary query language that has redefined the way we think about APIs. Unlike traditional REST APIs, GraphQL offers a more flexible and efficient approach to handling data requests and responses. Let’s unravel the core concepts of GraphQL and explore how NestJS enhances these features, guiding you to build more flexible and efficient APIs.

With GraphQL, clients can specify the exact shape and structure of the data they require from the server, reducing over-fetching and under-fetching issues, something that’s common in RESTful architectures.
