Installation

Open a workspace and click the workflow actions dropdown
Select GraphQL Query Generator: Settings to manage headers for the schema query and default headers for GraphQL operations

Headers are entered in JSON format eg. {"headerName": "headerValue", "anotherHeaderName": "anotherHeaderValue"} Insomnia environment variables can be used in the default headers, e.g. {"headerName": "{{_.envVarName}}"}
Select GraphQL Query Generator: From URL to import GraphQL operations via URL
- In the Import URL field, you must supply the full URL of the GraphQL api you are trying to import from e.g. http://mygraphqlserver.net/graphql
- In the Folder Name field, supply the base folder name that will be used (will be appended with '_queries', '_mutations' etc.)
- In the Generated Request Base URL field, supply the base URL for generated operations
  
  Environment variables can be used here, e.g. {{_.myBaseUrl}}

GraphQL generation largely borrowed and modified from James Gatz's graphql codegen plugin github
