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 ``` Head out to [docs] to learn about other powerful tailcall features.
