NestJS GraphQL Setup

Hello! In this lesson, you'll learn how to integrate GraphQL into your NestJS application. We'll cover the essential setup steps and explore two primary approaches:

• Schema-First: Defining your API using GraphQL Schema Definition Language (SDL).
• Code-First: Building your schema directly from TypeScript classes and decorators.

By the end, you'll be able to choose the best approach for your project and have a basic GraphQL server running!

Before we write any code, we need to install the necessary packages. NestJS uses @nestjs/graphql along with an underlying GraphQL library like Apollo.

Open your terminal and run the following command to add the required packages:

graphql is the core GraphQL library, and @nestjs/apollo provides the Apollo server integration.
