Building and optimizing a GraphQL API with NestJS

As we venture deeper into the world of GraphQL, we arrive at a pivotal moment in our journey: building and optimizing a GraphQL API using NestJS. This chapter is where theory meets practice, and we’ll apply our newfound knowledge of GraphQL to construct a real-world application. Our focus will be on developing the same user management system we built in Chapter 5 with REST APIs, but this time, we’ll harness the power of GraphQL to enhance its capabilities and efficiency.

Contextualizing our application

First, we’ll rebuild our user management system, a cornerstone project that includes basic features such as creating, retrieving, updating, and deleting user information. However, with GraphQL, we’ll approach these tasks with more finesse and flexibility. The goal is to demonstrate how GraphQL can transform the way we handle data operations, offering a more streamlined, client-centric approach compared...
