Usage

npx wgc federated-graph fetch-schema <name>

Description

The npx wgc federated-graph fetch-schema command allows you to fetch the latest valid Schema Definition Language (SDL) of a federated graph from the Cosmo platform’s control plane. You can use this command to retrieve the SDL and, if needed, pipe the output to a file.

By default, the output schema is set to the Router Schema. To use the Client Schema instead, specify the -c or --client-schema flag to the command.

Parameters

  • <name>: The name of the federated graph you want to fetch. Replace <name> with the name of the federated graph you wish to retrieve the SDL for.

Options

  • -n, --namespace : The namespace of the federated graph (Default: “default”).
  • -o, --out : Destination file for the SDL. Prints to standard output if not provided.
  • -c, --client-schema: Output the Client Schema instead of the default Router Schema.

Examples

npx wgc federated-graph fetch-schema production

Fetch the latest valid SDL of the federated graph named “production.”

npx wgc federated-graph fetch-schema production -o production-schema.graphql

Fetch the latest valid SDL of the federated graph named “production” and save it to a file named “production-schema.graphql.”

npx wgc federated-graph fetch-schema production --client-schema

Fetch the latest valid client SDL of the federated graph named “production”.

Notes

  • The npx wgc federated-graph fetch-schema command interacts with the Cosmo platform’s control plane to fetch the latest valid SDL of the specified federated graph. Ensure that you have the necessary permissions to perform this operation.
