GraphQL Playground

The @server directive's showcase option allows for hands-on experimentation with server configurations in a controlled environment. This feature simplifies the process of exploring and testing different settings. This enables experimenting with random configurations hosted, without the need to restart the server or affect existing setups.

Example Usage

schema @server(showcase: true) {
query: Query
}

type User {
notId: Int
notName: String
}

type Query {
notUser: User
@http(
url: "http://jsonplaceholder.typicode.com/users/1"
)
}

To test it out, append /showcase/graphql?config=YOUR_CONFIG_URL to your GraphQL base URL when querying the data.

Showcase

The above example shows loading a schema file from Tailcall's Github repository examples and querying it.

Performance and Security

  • Performance Impact: The showcase feature prioritizes flexibility and ease of testing over speed, leading to slower response times due to the overhead of dynamically applied configurations.
  • Security Risk: There's a potential security risk as it may allow unauthorized access to files and environment variables.

Due to these concerns, this mode is not recommended for production environments.
