npm i -g @tailcallhq/tailcall

yarn global add @tailcallhq/tailcall

brew tap tailcallhq/tailcall
brew install tailcall

curl -sSL https://raw.githubusercontent.com/tailcallhq/tailcall/master/install.sh | bash

docker pull ghcr.io/tailcallhq/tailcall/tc-server
docker run -p 8080:8080 -p 8081:8081 ghcr.io/tailcallhq/tailcall/tc-server

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!

schema
  @server(port: 8000, hostname: "0.0.0.0")
  @upstream(baseURL: "http://jsonplaceholder.typicode.com", httpCache: true) {
  query: Query
}

type Query {
  posts: [Post] @http(path: "/posts")
  user(id: Int!): User @http(path: "/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(path: "/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.

tailcall start ./jsonplaceholder.graphql
