 project serves as a boilerplate to jumpstart GraphQL-based applications with authentication features in NestJS. Upon downloading, it is essential to install all dependencies to ensure the project's underlying services and modules are operational.

Best practices for managing such a project include keeping dependencies up to date and auditing them regularly for security vulnerabilities. Regular updates can prevent potential compatibility issues and leverage improvements in performance and security patches. Additional tips include utilizing scripts in the 

 to streamline the setup and update processes, thus ensuring a consistent development environment.

In the context of a NestJS application, the code defines a GraphQL mutation, which is an operation that allows clients to modify backend data. It specifies a

Incorporating non-nullable types in GraphQL schema design is a robust practice to ensure the API consumer always receives expected data structures, which simplifies front-end development. It is also recommended to strictly type inputs and outputs to leverage TypeScript's compile-time checks, reducing the likelihood of runtime errors and enhancing overall code quality.

### Step 1: Setup the Project

The `graphql-auth-starter` project serves as a boilerplate to jumpstart GraphQL-based applications with authentication features in NestJS. Upon downloading, it is essential to install all dependencies to ensure the project's underlying services and modules are operational.

Best practices for managing such a project include keeping dependencies up to date and auditing them regularly for security vulnerabilities. Regular updates can prevent potential compatibility issues and leverage improvements in performance and security patches. Additional tips include utilizing scripts in the `package.json` to streamline the setup and update processes, thus ensuring a consistent development environment.

### Step 2: Define Schema

```ts
type User {
  id: ID!
  firstName: String!
  lastName: String!
  email: String!
  password: String!
}
```

```ts
type Query {
  login(loginInput: LoginInput!): LoginResponse!
}
```

In the context of a NestJS application, the code defines a GraphQL mutation, which is an operation that allows clients to modify backend data. It specifies a `signup` mutation with an input of type `SignupInput`, which must be provided, and it guarantees a non-nullable `SignupResponse` upon completion.

Incorporating non-nullable types in GraphQL schema design is a robust practice to ensure the API consumer always receives expected data structures, which simplifies front-end development. It is also recommended to strictly type inputs and outputs to leverage TypeScript's compile-time checks, reducing the likelihood of runtime errors and enhancing overall code quality.
