## Get Started

The below file is a standard `.graphQL` file, with a few additions such as `@server` and `@http` directives. So, basically, we specify the GraphQL schema and how to resolve that GraphQL schema in the same file, without having to write any code!

```graphql
schema @server(port: 8000, hostname: "0.0.0.0") @upstream(httpCache: 42) {
  query: Query
}

type Query {
  posts: [Post] @http(url: "http://jsonplaceholder.typicode.com/posts")
  user(id: Int!): User @http(url: "http://jsonplaceholder.typicode.com/users/{{.args.id}}")
}

type User {
  id: Int!
  name: String!
  username: String!
  email: String!
  phone: String
  website: String
}

type Post {
  id: Int!
  userId: Int!
  title: String!
  body: String!
  user: User @http(url: "http://jsonplaceholder.typicode.com/users/{{.value.userId}}")
}
```

Now, run the following command to start the server with the full path to the jsonplaceholder.graphql file that you created above.

```bash
tailcall start ./jsonplaceholder.graphql
```

    body
    user {
      name
    }
  }
}
```
